2022-07-01  Alex Tutubalin <lexa@lexa.ru>

LibRaw 0.21-Beta1

== Camera format support ==
 * Phase One/Leaf IIQ-S v2 support
 * Canon CR3 filmrolls
 * Canon CRM (movie) files
 * Tiled bit-packed (and 16-bit unpacked) DNGs
 * (non-standard) Deflate-compressed integer DNG files are allowed

== Camera support ==

* Canon EOS R3, R7 and R10
 * Fujifilm X-H2S, X-T30 II
 * OM System OM-1
 * Leica M11
 * Sony A7-IV (ILCE-7M4)
 * DJI Mavic 3
 * Nikon Z9: standard compression formats only

== Multiple (resolution) thumbnails support ==
 
 * New imgdata.thumbs_list data item with data fields:

int thumbcount: thumbnail count  
   libraw_thumbnail_item_t thumblist[LIBRAW_THUMBNAIL_MAXCOUNT]: list  of thumbnails

libraw_thumbnail_item_t fields:

enum LibRaw_internal_thumbnail_formats tformat: internal thumbnail format
        (this is not PPM/JPEG, but internal type related to thumbnail reading/unpacking method)

ushort twidth, theight: thumbnail image size.

ushort tflip: image rotation (see notes below)
    
     unsigned tlength: on-disk data size (not uncompressed for compressed formats)
     
     unsigned tmisc: bit depth and channel count:  (color << 5) | bitsperpixel
 
     INT64 toffset: Thumbnail data offset in file

Notes:
    -  Only TIFF-based and CR3 files are parsed for thumbnail list, other formats will have
       thumbcount = 1 (or 0 if no thumbnail found in file).

-  Thumbnail image size may be unknown (not recorded in metadata), in this case twidth and theight are zero.
       Usually small(er) thumbnails will always have twidth/theight filled, while largest one may have these fields set to zero.

-  Thumbnail rotation (tflip) is filled only for TIFF-based RAWs (if Orientation tag is not present in IFD, default zero value is used)
       For non-tiff images, tflip is initialized to 0xffff (not known...)

- There is no code to select thumbnail based on some criteria (e.g. minimal resolution), it is left to user to implement such a criteria, if needed
      (see unpack_thumb_ex() call below)

- If you want to get largest possible thumbnail: just use old unpack_thumb() call to get it.

* new API call:  LibRaw::unpack_thumb_ex(int i):
    Unpacks i-th thumbnail if it exists into imgdata.thumbnail structure
    i should be non-zero and less then imgdata.thumbs_list.thumbcount.  
     
  * samples/simple_dcraw.cpp: new -E command line switch to extract all thumbnails from input file(s)

== (Experimental) RawSpeed "version 3" (develop branch) support. ==

Build with -DUSE_RAWSPEED3, see details in RawSpeed3/README.md

LibRaw::capabilities will set bit LIBRAW_CAPS_RAWSPEED3 if compiled w/
   RawSpeed-v3 support

If file was processed (or tried to process) via RawSpeed-v3, these bits
   are raised in imgdata.process_warnings:
    LIBRAW_WARN_RAWSPEED3_PROCESSED - processed via RawSpeed v3
    LIBRAW_WARN_RAWSPEED3_PROBLEM - not processed (due to exception in RawSpeed library)
    LIBRAW_WARN_RAWSPEED3_UNSUPPORTED - unsupported file
    LIBRAW_WARN_RAWSPEED3_NOTLISTED - file not listed in cameras.xml data

RawSpeed-v3 support is controlled via libraw_decoder_info.t->flags 
  (LIBRAW_DECODER_TRYRAWSPEED3 bit).
  The bit is set for:
    - lossless jpeg decoder
    - Canon sRAW decoder
    - lossless compressed and packed-compressed DNG decoders
    - Pentax decoder
    - Nikon (compressed) decoder
    - Phase One Compressed and Hasselblad/Compressed decoders
    - bitpacked decoder
    - Panasonic (old 12-bit compression) decoder
    - Olympus decoder
    - Sony ARW (v1 and v2) decoders
    - Samsung (version 1) decoder

* (Experimental) Fine control of RawSpeed version selection/use.
   To enable, build LibRaw with -DUSE_RAWSPEED_BITS
   LibRaw::capabilities will set bit LIBRAW_CAPS_RAWSPEED_BITS if compiled
   with this flag.
   If enabled: 
     imgdata.rawparams.use_rawspeed becomes bit-field (instead of 0/1 off/on) 
     with bits:
        LIBRAW_RAWSPEEDV1_USE - use RawSpeed Version 1 (if compiled  with)
        LIBRAW_RAWSPEEDV1_FAILONUNKNOWN - do not process unknown files 
             (not listed in RawSpeed v1 camera definitions file)
        LIBRAW_RAWSPEEDV1_IGNOREERRORS - ignore mirror decoding errors (out of range data,etc)

LIBRAW_RAWSPEEDV3_USE - Use RawSpeed Version 3 (if compiled with)
        LIBRAW_RAWSPEEDV3_FAILONUNKNOWN - do not process unknown files
        LIBRAW_RAWSPEEDV3_IGNOREERRORS - ignore minor decoding errors
 
 == Misc changes/improvements ==
 * New compile time define LIBRAW_OWN_SWAB
   to use on platforms without swab() in C/C++ runtime

* New imgdata.rawparams.options bit: LIBRAW_RAWOPTIONS_CANON_IGNORE_MAKERNOTES_ROTATION
   If set: image orientation is set based on TIFF/IFD0:Orientation tag,
   makernotes orientation data is ignored

* Nikon makernotes: read NEFCompression tag for HE/HE* files

* Nikon orientation tag: more fixed offsets for known cameras

* Adobe DNG SDK 1.6 support (meaning, just an additional patch for GPR SDK)

* removed LibRaw::memerr(),  memory allocation failures are already handled
   in LibRaw_memmgr::*alloc w/ exception thrown

* removed memory error callback, out-of-memory error should be handled via
   returned error code check, all related parameters (e.g. LibRaw constructor
   option to not set such callback) is also removed

* imgdata.params.adjust_maximum_thr is settable via C-API libraw_set_adjust_maximum_thr(..)

* New rawoptions/processing flags for DNG processing if compiled 
   with Adobe DNG SDK:
   LIBRAW_RAWOPTIONS_DNG_STAGE2_IFPRESENT,LIBRAW_RAWOPTIONS_DNG_STAGE3_IFPRESENT
   If these flag(s) are set: Stage2/Stage3 processing will be performed
   only if OpcodeList2/OpcodeList3 tags are present in the input DNG file
   Old (hard) flags (LIBRAW_RAWOPTIONS_DNG_STAGE2 and 
   LIBRAW_RAWOPTIONS_DNG_STAGE3) are not removed and will force Stage2/3
   processing if set (regardless of input file tags)

* New imgdata.rawparams.options bit: LIBRAW_RAWOPTIONS_DNG_ADD_MASKS
   If set: DNG Transparency Masks will be extracted (if selected via shot_select)

* New decoder flag: LIBRAW_DECODER_UNSUPPORTED_FORMAT

== Bugs fixed ==

* Fixed possible out-of-buffer read in Nikon orientation tag parser

* Windows datastream: fixed logic errors (not showing up in real life)

* Out-of-range read-only array access in postprocessing if output_color is set to 0 (raw color)

* Minolta Z2 was not recognized correctly on 32-bit systems
 
 * Fixed possible buffer overflow in Kodak C330 decoder

* dcraw_process(): check for buffer allocation results to avoid NULL deref

 * Camera support:
   Apple iPhone 13 Pro
   GoPro HERO10 (if compiled w/ USE_GPR_SDK)
   Ricoh GR III
   Sony Xperia 1 III

* Fuji RAF files: XMP block extraction

* Fixed a typo in LIBRAW_OPTIONS_* flag names
   (was LIBRAW_OPIONS, old flags names not removed due to compatibility)

* samples/raw-identify.cpp:  -v flag documented in usage print.

2021-09-14  Alex Tutubalin <lexa@lexa.ru>
 * Camera support:
   Fujifilm GFX 50S II
   Nikon Z fc
   Sony A7R-IIIA (ILCE-7RM3A), A7R-IVA (ILCE-7RM4A)

* API/datastruct Changes:
  - imgdata.params.shot_select moved to imgdata.rawparams.shot_select
   (because this is decode-time option, not postprocessing option)

- libraw_open_bayer(...) added to C-API

- imgdata.makernotes.canon: separate SensorLeftBorder,SensorTopBorder....
    (and many other datafields) are united in libraw_area_t (rectangle)
    groups for crop areas and optical black areas.

* src/libraw_cxx.cpp completely removed from source tree to not confuse users.
   (also all mentions are removed from Makefiles)

* Better Olympus makernotes parsing: LiveND mode, Panorama mode tags.

* clang-cl compatibility:
  - defines _MSC_VER, but _forceinline is not supported
  - warnings eliminated in Windows buffered datastream

* Canon/12-bit files: adjust color.linear_max and makernotes.canon values
   to match data range.

2021-08-04  Alex Tutubalin <lexa@lexa.ru>
 * Camera support:
   Sony ZV-E10
 * DNG/Floating point: additional metadata check to refuse ambiguous/corrupted files.
 * DNG/Floating point: correct handling of striped files (never seen in wild)
 * Rawspeed support: disallow Nikon D6/Compressed processing
 * Bug fixed: raw_inset_crops[] ctop/cheight was not adjusted right if vendor-specified 
   ctop equals to 1.

    LIBRAW_MAX_DNG_RAW_FILE_SIZE - max DNG file size limit (4GB-1 if compiled w/ DNG SDK, 2GB-1 otherwise)
 
 * ACES output: color conversion changed to provide D65 white point

* Fix for Canon 5D Mark II/sRAW1 incorrect camera provided crop

     use_camera_matrix.
   - full-size thumbnail/preview support for JPEG+RAW files (raspistill -r)
 * Fuji GFX100/GFX100S: PixelShift metadata extraction.
 * RawSpeed (master): fixed bug in old Samsung/compressed decoder,
   apply this patch to RawSpeed: RawSpeed/rawspeed.samsung-decoder.patch

2021-02-18  Alex Tutubalin <lexa@lexa.ru>
 * Improved Phase One Compressed defects masking, thanks to Alexey Danilchenko
 * Sony ILCE-1/Lossless compressed support
 
2021-02-16  Alex Tutubalin <lexa@lexa.ru>
 * Additional fields in libraw_internal_data.unpacker_data:
   - INT64: exif_offset: base offset of 1st EXIF IFD in file
   - INT64: ifd0_offset: base offset of 1st TIFF IFD (IFD0) in file
   - unsigned cr3_exif_length, cr3_ifd0_lenght : CR3-specific length of
     exif and ifd0 sections.

2021-02-08  Alex Tutubalin <lexa@lexa.ru>
 * CRX (CR3) decoder: fixed typo in constant; this does not affect any
   known still photo (CR3) sample(s), but allows to use the decoder with 
   some video (CRM) files.

* Imported user-contributed improvements to OpenMP postprocessing
   (AHD and X-Trans demosaic)

* Bugfix: overwrite (wrong) TIFF/Orientation tag value with Metadata/Camera Orientation
   value for EOS 40D only.

2021-02-04  Alex Tutubalin <lexa@lexa.ru>
 * imgdata.sizes.raw_inset_crop rearranged:
   now it is imgdata.sizes.raw_inset_crops[2]:
    - item at [0] is the same as imgdatra.sizes.raw_inset_crop in previous 
      versions
    - item at [1] is 'user crop', in particular:
       -- set by DNG  DefaultUserCrop tag
       -- or set via raw aspect ratio tags (e.g. 16:9 aspect on Fujifilm cameras)
          raw_inset_crops[1] is filled only if aspect ratio tags provides different
          aspect ratio compared to raw_inset_crops[0].

There are no flags to check if raw_inset_crops[Nth] is filled; to see if it is filled check 
   the values of:
     ctop/cleft < 0xffff (0xffff => standard values if not initialized)
     ctop+cheight <= sizes.raw_height
     cleft+cwidth <= sizes.raw_width

Note: raw_inset_crops may be fooled by metadata (makernotes), use some correctness check before use.

* LIBRAW_RAWOPTIONS_USE_DNG_DEFAULT_CROP processing flag removed,
   DNG DefaultCrop* tags are parsed into raw_inset_crops[0]

* new LibRaw call LibRaw::adjust_to_raw_inset_crop(unsigned mask, float maxcrop = 0.55f)
   Promotes imgdata.sizes.raw_inset_crops[] values to
   imgdata.sizes.*margin and imgdata.sizes.width/height fields

mask: if bit 1 is set: prefer raw_inset_crops[1] 
         if bit 0 is set: prefer raw_inset_crops[0]

maxcrop: limits crop to not less than (original width/height)*maxcrop; if raw_inset_crops[i]
   data results in tighter crop, than this item is ignored.

return value: index in raw_inset_crops[] used increased by one, so
    0: no changes made
    1: [0]th data used
    2: [1]th data used
   
  Note: this call SHOULD be used after LibRaw::unpack(), otherwise black level
  calculation from masked area may be fooled resulting in wrong black levels.

== LibRaw snapshot 202101 ==

= Camera format support: =
   Lossy compressed CR3 files
   Lossy compressed RAF files
   Uncompressed floating point DNG files (16-24-32 bit)
   Deflate compressed striped DNG files
   XMP and HEIF-preview extraction from CR3 files

=  Camera support =
   Apple iPhone 12 Max, iPhone 12 Max Pro
   Canon EOS R5, EOS R6, EOS 850D, EOS-1D X Mark III (lossy compressed files)
   FujiFilm X-S10
   Hasselblad CFV II 50C",
   Leica M10-R, Q2 Monochrom, S3, SL2-S
   Nikon Z 5, Z 6 II, Z 7 II
   Olympus E-M10 Mark IV
   Panasonic DC-G100 / G110, DC-S5
   Sony ILCE-7C (A7C), ILCE-7SM3 (A7S III)
   Zeiss ZX1
   Plus multiple DNG-recording cameraphones/drones/etc.

= Almost dropped camera support: =
   Old/partially supported video/cinema cameras support is available only if
   LibRaw is compiled with USE_OLD_VIDEOCAMS defined (this #define is
   converted internally to LIBRAW_OLD_VIDEO_SUPPORT defined).
   This affects:
     Arri cameras
     Canon C500
     RED Cine cameras
   We plan to keep the support in LibRaw 0.21 (if compiled with define 
   mentioned above) and completely drop the support after 0.21.
   If you're using LibRaw to decode RED Cine files, see LibRaw*datastreams
   section below (in short: you'll need to use old fstream-based datastream 
   under Windows).
   Cinema DNG files are not affected by this.

= API/ABI changes =

* Decoding parameters
    imgdata.params is split into
      imgdata.rawparams: parameters used for metadata/raw data decoding
      imgdata.params:  parameters used at postprocessing stage

imgdata.params.raw_processing options are split into two sub-options sets
      imgdata.rawparams.options: raw processing flags, useful for normal 
      operations
      imgdata.rawparams.specials: special modes (e.g decoding only delta 
      pixels from Sony ARW)

Old LIBRAW_PROCESSING_* flags are renamed to LIBRAW_RAWOPTIONS_* and 
    LIBRAW_RAWSPECIAL*
   LIBRAW_PROCESSING_DP2Q_INTERPOLATE... flags are renamed to 
   LIBRAW_RAWSPECIAL_NODP2Q_INTERPOLATE with inverted meaning (with the 
   goal to have zero imgdata.rawparams.specials in normal use).

* New processing flag LIBRAW_RAWOPTIONS_PROVIDE_NONSTANDARD_WB
   If set (default is not), and when applicable, color.cam_mul[] and
   color.WB_Coeffs/WBCT_Coeffs will contain WB settings for a
   non-standard workflow.
   Right now only Sony DSC-F828 is affected: camera-recorded white balance
   can't be directly applied to raw data because WB is for RGB, while raw
   data is RGBE.

* New processing flag: LIBRAW_RAWOPTIONS_CAMERAWB_FALLBACK_TO_DAYLIGHT
   If set (default is not), LibRaw::dcraw_process() will fallback to
   daylight WB (excluding some very specific cases like Canon D30).
   This is how LibRaw 0.19 (and older) works.
   If not set: LibRaw::dcraw_process() will fallback to calculated auto WB if
   camera WB is requested, but appropriate white balance was not found in
   metadata.

* Removed LIBRAW_PROCESSING_SKIP_MAKERNOTES processing flag: with new
    Windows(-handle) datastreams metadata parsing performance is enough
    to not skip makernotes parsing.

* new output parameter: imgdata.params.output_flags and new
    enum LibRaw_output_flags
    Right now the only flag is implemented: LIBRAW_OUTPUT_FLAGS_PPMMETA
    setting it will result into metadata written to PPM/PGM output file

* LibRaw_*datastreams change and corresponding open_file() parameters change
   LibRaw_file_datastream (based on iostreams) is moved under
      #ifdef LIBRAW_USE_DEPRECATED_IOSTREAMS_DATASTREAM
    Standard datastreams are:
     LibRaw_bigfile_datastream (FILE* based) for POSIX systems
     LibRaw_bigfile_buffered_datastream - for use with Win32 syscalls
    API changes:
    if LIBRAW_USE_DEPRECATED_IOSTREAMS_DATASTREAM is NOT defined, than 
    LibRaw::open_file() and similar calls drops the last INT64 max_buffered_sz 
    parameter which defines automatic selection between iostreams and 
    FILE* based datasteams.

Note: LibRaw_bigfile_buffered_datastream does NOT implements 
    make_jas_stream() call, so RED Cine file decoding is not possible with 
    this datastream. Use deprecaded iostreams implementation instead.

We plan to keep LIBRAW_USE_DEPRECATED_IOSTREAMS_DATASTREAM up to 
    LibRaw 0.21 and drop in 0.22.

* Fuji decoder:
    fuji_decode_loop/fuji_decode_strip parameters has changed; look into source
    code for details if you're implementing your own fuji_decode_loop() 
    call in subclass to provide parallel fuji decoding.

* Canon CR3 H265 (HEIF) preview limited support:
    - new format value: LIBRAW_THUMBNAIL_H265
    - this thumbnail is NOT extracted by LibRaw::make_mem_thumb() yet;

* LibRaw::capabilities
    Two bits added:
      LIBRAW_CAPS_ZLIB if compiled with USE_ZLIB
      LIBRAW_CAPS_JPEG if compiled with USE_JPEG

* Windows datastreams: CreateFile2 is used if compiled for UWP.

* API-datastruct: clarified behavior with use_camera_wb=1 setting.

* identify(): restored the differentiation between fsize and flen.

* New compile-time LIBRAW_FORCE_OPENMP to skip compiler version check
   (if LibRaw user is absolutely sure that OpenMP is supported by compiler)

2020-10-14 Alex Tutubalin <lexa@lexa.ru>

* LibRaw 0.20.2
 Reverted 0.20.1 change:
   - const buffer for open_buffer() and open_bayer() calls
 Because of 0.20.0 ABI break

2020-10-14 Alex Tutubalin <lexa@lexa.ru>

* LibRaw 0.20.1
 * Improvements:
   - exif callback is called on EXIF GPS and EXIF Interop IFDs
   - open_bayer call documented
   - Canon (ColorDatsSubver==32): parse Specular White instead of hardcoded value
 * Fixes for normal files processing:
   - Olympus XZ-1: do not provide linear_max (it is wrong in metadata)
   - Nikon Z cameras: added space in camera list
   - raw-identify: fixed wb-preset print
   - Pentax Optio 33WR: maker index was incorrect
   - dcraw_emu: corrected help line for -6 option.
   - raw-identify: corrected range check for color matrices print
   - use_camera_matrix option: fixed a bug introduced when making
     compiler more happy.

* Fixes for damaged/special crafted files processing:
   - Fix for truncated CR3 files parsing
   - DNG metadata merger: all color loops are limited to MIN(4,colors)
   - Check for marings: should be less than raw image size
   - Check for xmpdata present in Samsung Lens ID assignment
   - Check for column range in leaf_hdr decoder
   - Additional checks in Hasselblad model parser
   - Fuji rotate: better limits check
   - DNG files: limit tiff_samples

* Not fixes, but makes ASAN/compilers/etc happy:
   - corrected GPS EXIF output
   - const buffer for open_buffer() and open_bayer() calls

  Sony A7R IV, A9 II, ILCE-6100, ILCE-6600, RX0 II, RX100 VII
  Zenit M

also multiple smartphones (the tested ones are listed in LibRaw::cameraList)

== Source code re-arranged ==
 * dcraw.c is not used in the generation and build processes
 * dcraw_common.cpp and libraw_cxx.cpp are split into multiple code chunks
   placed in separate subfolders (decoders/ for raw data decoders,
   metadata/ for metadata parsers, etc)
 * dcraw_common.cpp and libraw_cxx.cpp remain to preserve existing
   build environments (these files are now just a bunch of #include directives).
 * It is possible to build LibRaw
    a)without postprocessing functions (dcraw_process() and  called function)
    b)without postprocessing and LibRaw::raw2image() call (and called function).
   It may be useful to reduce library memory/code footprint.
   See Makefile.devel.nopp and Makefile.devel.noppr2i for the list of source
   files needed to build reduced/stripped library.

== Normalized make/model ==

There is a huge number of identical cameras sold under different names,
depending on the market (e.g. multiple Panasonic or Canon models)
and even some identical cameras sold under different brands
(Panasonic -> Leica, Sony -> Hasselblad).

To reduce clutter, a normalization mechanism has been implemented in LibRaw:

In imgdata.idata:
    char normalized_make[64]; - primary vendor name (e.g. Panasonic for
    Leica re-branded cameras)
    char normalized_model[64]; - primary camera model name
    unsigned maker_index; - primary vendor name in indexed form (enum
       LibRaw_cameramaker_index, LIBRAW_CAMERAMAKER_* constant).
These fields are always filled upon LibRaw::open_file()/open_buffer() calls.

const char* LibRaw::cameramakeridx2maker(int index): converts maker_index
to normalized_make.

We recommend that you use these normalized names in a variety of data tables
(color profiles, etc.) to reduce the number of duplicate entries.

New vendor index values will be added strictly to the end of the
LibRaw_cameramaker_index table, ensuring that the numbers assigned to
vendors that are already known to LibRaw will not change.

== DNG frame selection  ==

DNG frames selection code re-worked:
  - by default all frames w/ the NewSubfileType tag equal to 0
  (high-res image) are added to the list of available images (selection
  performed via imgdata.params.shot_select field, as usual)
  - the special case for Fuju SuperCCD (SamplesPerPixel == 2) works as
  before: shot_select=1 will extract second sub-image.
  - Additional flags to imgdata.params.raw_processing_options:
     LIBRAW_PROCESSING_DNG_ADD_ENHANCED - will add Enhanced DNG frame
     (NewSubfileType == 16) to the list of available frames
     LIBRAW_PROCESSING_DNG_ADD_PREVIEWS - will add previews
     (NewSubfileType == 1) to the list.

- By default, DNG frames are not reordered and are available in same order
  as in DNG (LibRaw traverses IFD/Sub-IFD trees in deep-first order).
  To prioritize the largest image, set LIBRAW_PROCESSING_DNG_PREFER_LARGEST_IMAGE
  bit in imgdata.params.raw_processing_options.

- DNG Stage2/Stage3 processing via DNG SDK (request via flags in
 raw_processing_options)

== Imported code policy disclaimer ==

We've changed the policy regarding 3rd party code imported into LibRaw.

We (like other authors of open-source RAW parsers) gladly import support
  code for various RAW formats from other projects (if the license allows it).
  This is done to expand camera support.
  Unfortunately, not all imported code can tolerate truncated or otherwise
  damaged raw files, as well as arbitrary conditions or arbitrary data;
  not all authors handle rejecting unexpected input well.

LibRaw is now widely used in various projects, including ImageMagick, which,
  in turn, is often used on web sites to process any input images, including
  arbitrary data from unknown users.
  This opens up wide possibilities for exploiting the various vulnerabilities
  present in the code borrowed from other projects into LibRaw. In order to
  avoid such security risks, - the borrowed code will no longer compile
  by default.
  We are not able to support it in general case, and the authors refuse
  to add code to reject unexpected input.

Thus, if you use some kind of camera for which the support is disabled
  by default, you need to recompile LibRaw for your specific case.

Formats currently affected:
   X3F (Foveon) file format.
    Code is imported from Kalpanika X3F tools: https://github.com/Kalpanika/x3f
    To turn the support on, define USE_X3FTOOLS

Rapsberry Pi RAW+JPEG format.
     Code is imported from https://github.com/6by9/dcraw/,
     To turn the support on, define USE_6BY9RPI
  Format support is indicated via LibRaw::capabilities() call with flags:
    LIBRAW_CAPS_X3FTOOLS - Foveon support
    LIBRAW_CAPS_RPI6BY9 - RPi RAW+JPEG support

== GoPro .gpr format support ==
 GoPro  format supported via open-source GPR SDK
 See README.GoPro.txt for details.

== Windows support/Windows unicode (wchar_t*) filenames support ==

* (old) LibRaw's WIN32 external define split into 3 defines to fine tune
  compiler/api compatibility:
  LIBRAW_WIN32_DLLDEFS - use to compile DLLs (__dllimport/__dllexport attributes)
  LIBRAW_WIN32_UNICODEPATHS - indicates that runtime has calls/datatypes for wchar_t filenames
  LIBRAW_WIN32_CALLS - use Win32 calls where appropriative (binary mode for files, LibRaw_windows_datastream, _snprintf instead of snprintf, etc).

If the (old) WIN32 macro is defined at compile time, all three new defines are defined in libraw.h
  If not, these defines are defined based on compiler version/libc++ defines

* LibRaw::open_file(wchar_t*) is always compiled in under Windows, but
  if LIBRAW_WIN32_UNICODEPATHS (see above) is not defined, this call will
  return LIBRAW_NOT_IMPLEMENTED.
  Use (LibRaw::capabilities() & LIBRAW_CAPS_UNICODEPATHS) on runtime
  to check that this call was really implemented (or check for #ifdef LIBRAW_WIN32_UNICODEPATHS after #include <libraw.h>)

== LibRaw*datastream simplified ==

* tempbuffer_open, subfile_open are not used, so removed from
  LibRaw_abstract_datastream and derived classes.

* jpeg_src() call implemented using ->read() call and own buffering
  (16k buffer).
  * buffering_off() call added. It should be used in derived classes
    to switch from buffered reads to unbuffered.

== minor/unsorted changes ==
   * new flag LIBRAW_WARN_DNGSDK_PROCESSED to indicate decoder used
   *  LibRaw::open() call, max_buf_size special meaning:
       == 1 => open using bigfile_datastream
       == 2 => open using file_datastream
   * Add support for zlib during configure
   * Fixed multiple problems found by OSS-Fuzz
   * Lots of changes in imgdata.makernotes (hope someone will document it)
   * DNG SDK could be used (if enabled) to unpack multi-image DNG files.
   * DNG whitelevel calculated via BitsPerSample if not set via tags.
   * DNG: support for LinearDNG w/ BlackLevelRepeat.. pattern
   * Generic Arri camera format replaced w/ list of specific camera models in supported cameras list.
   * new samples/rawtextdump sample: allows one to dump (small selection) of RAW data in text format.
   * samples/raw-identify:
     * +M/-M params (same as in dcraw_emu)
     * -L <file-w-filelist> parameter to get file list from a file
     * -m paramerer to use mmap'ed IO.
     * -t parameter for timing
   * samples/dcraw_emu: fixed +M handling
   * better support for Nikon Coolscan 16-bit NEF files.
   * Visual Studio project files: re-generated to .vcxproj (Visual Studio 2019), different
     intermediate folders for different sub-projects to allow 1-step rebuild.
   * imgdata.makernotes...cameraspecific: removed the vendor name prefix from variables.
   * Bayer images: ensure that even margins have the same COLOR() for both the active sensor area and the full sensor area.
   * raw processing flag bit LIBRAW_PROCESSING_CHECK_DNG_ILLUMINANT inverted and renamed to
     LIBRAW_PROCESSING_DONT_CHECK_DNG_ILLUMINANT. If not set, DNG illuminant will be checked.
   * New libraw_decoder_t flags:
      LIBRAW_DECODER_FLATDATA - in-file data could be used as is (if byte order matches), e.g. via mmap()
      LIBRAW_DECODER_FLAT_BG2_SWAPPED - special flag for Sony ARQ: indicates R-G-G2-B channel
                                        order in 4-color data
   * Camera-recorded image crop data is parsed into imgdata.sizes.raw_inset_crop structure:
	ctop,cleft,cwidth,cheight - crop size.
	aspect - LibRawImageAspects enum (3to2, 4to3, etc)
   * New define LIBRAW_NO_WINSOCK2 to not include winsock2.h on compile

* New processing flag LIBRAW_PROCESSING_PROVIDE_NONSTANDARD_WB
   If set (default is not), and when applicable, color.cam_mul[] and
   color.WB_Coeffs/WBCT_Coeffs will contain WB settings for a non-standard
   workflow.
   Right now only Sony DSC-F828 is affected: camera-recorded white balance
   can't be directly applied to raw data because WB is for RGB, while raw
   data is RGBE.

* New processing flag: LIBRAW_PROCESSING_CAMERAWB_FALLBACK_TO_DAYLIGHT
   If set (default is not), LibRaw::dcraw_process() will fallback to
   daylight WB (excluding some very specific cases like Canon D30).
   This is how LibRaw 0.19 (and older) works.
   If not set: LibRaw::dcraw_process() will fallback to calculated auto WB if
   camera WB is requested, but appropriate white balance was not found in
   metadata.

* Google changes cherry-picked (thanks to Jamie Pinheiro)
  * speedup: ppg interpolate: const loop invariant

* Bugs fixed
   -Fixed several UBs found by OSS Fuzz
   -Fixed several problems found by other fuzzers.
   - Thumbnail size range check (CVE-2020-15503)
    Thanks to Jennifer Gehrke of Recurity Labs GmbH for problem report.
   - fixed possible overflows in canon and sigma makernotes parsers
   - fixed possible buffer overrun in crx (cr3) decoder
   - fixed memory leak in crx decoder (if compiled with LIBRAW_NO_CR3_MEMPOOL)
   - fixed possible overrun in Sony SRF and SR2 metadata parsers

* Fixed typo in longitude (member of parsed GPS structure), update required for code that uses it.

2019-03-05 Alex Tutubalin <lexa@lexa.ru>
 * Camera support
   Canon A560 (CHDK hack)
   FujiFilm X-T30
   Nikon Coolpix A1000
   Olympus E-M1X
   Sony ILCE-6400
   Several dng files from phones and drones was tested
   and added to built-in camera list too.

* Multiple names for same Panasonic cameras are processed via
   aliaces mechanics, no multiple duplicate fields in adobe_coeffs() table

* Better makernotes parsing for many cameras

* Better parsing of makernotes embedded into DNG files created by
   Adobe DNG Converter

* New imgdata.params.raw_processing_options value: LIBRAW_PROCESSING_ZEROFILTERS_FOR_MONOCHROMETIFFS
    - If this bit is set
    - and TIFF file contains SamplesPerPixel == 1
    - and filters value was not guessed from metadata parsing
   LibRaw will assume the file is monochrome, not bayer.
 This option is needed for monochrome scan processing (Imacon X1 etc).
 This option may broke old TIF-like RAW files processing (Kodak 760,etc)
 use with care (it is better to let user choose).

2018-12-12 Alex Tutubalin <lexa@lexa.ru>
 * Camera support:
     Canon: PowerShot A480 (CHDK hack), EOS 2000D, EOS 4000D

  * Better parsing for NEF files modified (damaged) by NikonTransfer
  * Better parsing for floating point DNG black levels (into color.dnglevels.fblack and dng_fcblack[], similar
    to color.black and color.cblack[] for other formats).
  * More flexible limit for RAW decoding memory usage:
      imgdata.params.max_raw_memory_mb (default is LIBRAW_MAX_ALLOC_MB_DEFAULT)

* New flags for imgdata.params.raw_processing_options:
    LIBRAW_PROCESSING_CHECK_DNG_ILLUMINANT - will check DNG illuminant field when selecting color matrix
      (note: incompatibility with previous versions, so default is not set).
    LIBRAW_PROCESSING_DNGSDK_ZEROCOPY - will not copy data from Adobe DNG SDK decoded buffer, but use it as is

* Switched from auto_ptr to unique_ptr, to get back define LIBRAW_USE_AUTOPTR

* dcraw_emu: it is now possible to create output filename in a more flexible manner, via -Z switch:
     -Z - will output to stdout
     -Z ext will output into inputfilename.ext
     -Z .ext will output into inputfilename.inputext.ext

2018-11-22  Alex Tutubalin <lexa@lexa.ru>

Note(*): for mobile phones with DNG format recording, only really tested cameras
  are added to supported camera list. Really LibRaw should support any correct DNG.

* No more built-in support for LibRaw demosaic packs (GPL2/GPL3).
   We're unable to support this (very old code), so we'll be happy to transfer this
   code to some maintainer who wish to work with it.

In LibRaw 0.19 we provide extension API: user-settable callbacks to be called in
   code points where demosaic pack code was called.

-  int callbacks.pre_identify_cb(void *) => to be called in LibRaw::open_datastream
       before call to (standard) identify() function. If this call returns 1, this means
       that RAW file is identified and all metadata fields are set, so no need to run
       standard identify code.
   - void callbacks.post_identify_cb(void*) => called just after identify(), but before
       any cleanup code;
   - dcraw_process() callbacks are called before dcraw_process phases (name speaks for itself):
       	pre_subtractblack_cb, pre_scalecolors_cb, pre_preinterpolate_cb, pre_interpolate_cb,
	interpolate_bayer_cb, interpolate_xtrans_cb, post_interpolate_cb, pre_converttorgb_cb,
	post_converttorgb_cb

All these new callbacks are called with (this) as the only arg.
   To continue LibRaw-demosaic-pack-GPLx support one need to subclass LibRaw, set needed
   callbacks in (e.g.) constructor code, than these callbacks to be called

* Better DNG parser:
    - support for DefaultCrop Origin/Size tags (add LIBRAW_PROCESSING_USE_DNG_DEFAULT_CROP to raw_processing_options to enable)
    - better parsing for nested DNG tags (use tag from RAW IFD, fallback to IFD0 if no tag in current IFD)
    - DNG PreviewColorspace extracted into dng_levels.preview_colorspace

* Metadata extraction:
  - Better extraction of camera measured balance (LIBRAW_WBI_Auto and WBI_Measured),
    this not the same as 'as shot' if some preset/manual tune is used.
  - Extraction of camera custom balances (LIBRAW_WBI_CustomN)
  - Nikon data compression tag extracted into  makernotes.nikon.NEFCompression
  - Hasselblad BaseISO and Gain extracted into makernotes.hasselblad
  - Canon multishot params extracted into makernotes.canon.multishot
  - lot of other vendor-specific makernotes data (see data structures definitions for details).

* New LibRaw::open_bayer call allows to pass sensor dump w/o metadata directly to LibRaw:
     virtual int open_bayer(unsigned char *data, unsigned datalen,
	  ushort _raw_width, ushort _raw_height, ushort _left_margin, ushort _top_margin,
	  ushort _right_margin, ushort _bottom_margin,
	  unsigned char procflags, unsigned char bayer_pattern, unsigned unused_bits, unsigned otherflags,
	  unsigned black_level);
    Parameters:
     data, datalen - buffer passed
     width/height/margins - speaks for itself
     procflags:
     for 10-bit format:
      1: "4 pixels in 5 bytes" packing is used
      0: "6 pixels in 8 bytes" packing is used
     for 16-bit format:
      1: Big-endian data
    bayer_pattern: one of LIBRAW_OPENBAYER_RGGB,LIBRAW_OPENBAYER_BGGR,
                          LIBRAW_OPENBAYER_GRBG,LIBRAW_OPENBAYER_GBRG
    unused_bits: count of upper zero bits
    otherflags:
      Bit 1 - filter (average neighbors) for pixels with values of zero
      Bits 2-4 - the orientation of the image (0=do not rotate, 3=180, 5=90CCW, 6=90CW)
    black_level: file black level (it also may be specified via imgdata.params)

see samples/openbayer_sample.cpp for usage sample (note, this sample is 'sample only', suited for
    Kodak KAI-0340 sensor, you'll need change open_bayer() params for your data).

* Color data added/updated/fixed for many cameras

* Correct data maximum for Fuji X-* cameras

* Thumbnail processing:
   - JPEG thumbnails: if compiled with libjpeg, color count is extracted into imgdata.thumbnail.tcolors
   - PPM (bitmap) thumbnails: color count is set according to thumbnail IFD tag
   - PPM16 thumbnails: if LIBRAW_PROCESSING_USE_PPM16_THUMBS set in raw_processing_options, than thumbnail will be extracted
     as is, not converted to 8 bit. thumbnail.tformat is set to LIBRAW_THUMBNAIL_BITMAP16 in this case.
     Untested, because it is hard to find RAWs with 16-bit bitmaps.

== Compatibility fixes

* struct tiff_tag renamed to libraw_tiff_tag

* Floating point DNG support:
    - new data fields:
      imgdata.rawdata.float_image - bayer float data
      imgdata.rawdata.float3_image - 3-component float data
      imgdata.rawdata.float4_image - 4-component float data
      imgdata.color.fmaximum - float data maximum (calculated from real data,
          rounded to 1.0 if below 1.0)
   - new raw processing flag
      LIBRAW_PROCESSING_CONVERTFLOAT_TO_INT - converts float data to 16-bit
        integer immediately after decoding with default parameters
   - new API Calls:
      int LibRaw::is_floating_point() returns non-zero if RAW file contains
          floating point data
      int LibRaw::have_fpdata() returns non-zero if rawdata.float*_image is not
        null (so FP data has been unpacked but not converted to integrer, see below).
      LibRaw::convertFloatToInt(float dmin=4096.f, float dmax=32767.f, float dtarget = 16383.f)
        converts float/float3/float4_image to raw_image/color3/color4_image with or without scaling:
       - if both real data maximum and metadata maximum are within the range ( >= dmin && <=dmax), float
         data is just converted to integer
       - if data is out of the range given above, values are scaled so real data maximum becomes dtarget
       - if data was rescaled (normalized), scale multiplier is stored in imgdata.color.fnorm

* LibRaw can be built with Adobe DNG SDK support to decode exotic DNG formats (e.g. 8 bit).
   See README.DNGSDK.txt for details

* New API calls
    unsigned LibRaw::capabilities and C-API libraw_capabilities()
    allows developers to determine LibRaw compile flags at runtime.
    Returns ORed bit fields:
    LIBRAW_CAPS_RAWSPEED - LibRaw was compiled with RawSpeed Support
    LIBRAW_CAPS_DNGSDK - LibRaw was compiled with Adobe DNG SDK
    LIBRAW_CAPS_DEMOSAICSGPL2, LIBRAW_CAPS_DEMOSAICSGPL3 - LibRaw was compiled with demosaic packs (GPL2/GPL3)

* More metadata parsed:
    - White balance coefficients stored in the raw file are extracted into:
     int imgdata.color.WBCoeffs[256][4] - array indexed by EXIF lightsource type
        for example, WBCoeffs[21][..] contains coefficients for D65 lightsource
     float imgdata.color.WBCT_Coeffs[64][5] contains white balance data specified
       for given color temperature: WBCT_Coeffs[i][0] contains temperature value,
       and [1]..[4] are WB coefficients.
    - DNG analog balance, per-channel black/white level, and forward matrix
    - vendor specific metadata stored in vendor-specific data structures

* new C-API calls:
    void libraw_set_user_mul(libraw_data_t *lr,int index, float val);
    void libraw_set_ca_correction(libraw_data_t *lr,int ca_correc, float ca_red, float ca_blue);
    void libraw_set_cfalinenoise(libraw_data_t *lr,int cfaline, float linenoise);
    void libraw_set_wf_debanding(libraw_data_t *lr, int wf_debanding, float wfd0, float wfd1, float wfd2, float wfd3);
    void libraw_set_interpolation_passes(libraw_data_t *lr,int passes);

* Existing API changes:
    imgdata.params fields (all very specific purpose): sony_arw2_options, sraw_ycc, and params.x3f_flags
    replaced with single bit-field raw_processing_options
    See  LIBRAW_PROCESSING_* bits in documentation.

* zlib library is optional
   Use -DUSE_ZLIB to compile with zlib (to provide deflate DNG support)
 * libjpeg version: jpeg_mem_src() is mandatory, so use libjpeg-turbo
   or libjpeg 8+
 * Fixes in vng_interpolate to make modern compilers happy
 * Fixed bug in Sony SR2 files black level
 * DNG files with BlackLevel both in vendor makernotes and BlackLevel:
    BlackLevel tag always takes precedence
 * strlen replaced with strnlen in most cases, added local version of strnlen
 * ChannelBlackLevel added to canon makernotes
 * unpack_thumb() data size/offset check against file size

2015-08-15  Alex Tutubalin <lexa@lexa.ru>

* LibRaw 0.17

* More metadata parsing/extraction:
    - XMP packet extracted (if exists)
    - DNG Color information parsed
    - GPS data (partially) parsed
    - EXIF/Makernotes parsed for used optics (for both RAW files and DNG converted by Adobe convertor).

* Exif/Makernotes parser callback (called for each processed tag)

* Sony ARW2.3 decoder:
   - params.sony_arw2_hack removed, decoded data are always in 0...17k range (note the difference with dcraw!)
   - Additional processing options for Sony lossy compression technical analysis.

* Dcraw 9.26 imported (but some changes not approved because Libraw do it better) with some exceptions:
    - no Pentax K3-II frame selection code
    - no built-in JPEG decompressor

* Many improvements in data decoding/processing:
    - Correct decoding of black level values from metadata for many formats, LibRaw do not rely on hardcoded black levels.

* 224 camera models added to supported camera list.
   Some of them are new (released since LibRaw 0.16 come out), some was supported before, but missed from the list.

     Olympus E-M1
  * Corrected image visible area sizes
    Canon G16
    Sigma pre-Merrill cameras: small and medium-sized RAWs

* Sony cameras model name is set by SonyModelID EXIF tag

* Sony ARW2: black level and color matrix extracted from EXIF data

* Samsung: black level and color matrix extracted from EXIF;
    Camera multipliers are now extracted correctly even if black is not 0

* Better source compatibility with Mac OS X compilation

* Better source compatibility with Win32 compilation

* DNG without Compression tag assumed uncompressed

* Better X3F-tools based Foveon support:
    - new Foveon metadata parser based on X3F-tools. So, if LibRaw compiled
      without demosaic-pack-GPL2, then no dcraw Foveon code used.
    - Support for Medium resolution RAWs from DPx Merrill and SD1 cameras.
      RAW data extracted as is (4800x1600 pixels), aspect ratio is set to
      0.5, so these RAWs are processed to full-size 4800x3200 RGB.
    - Support for Foveon thumbnail extraction. Only JPEG and bitmap
      thumbnails extracted, but 'foveon' (RAW) thumbnails are really not used
      in production cameras.
    - New imgdata.params.force_foveon_x3f flag
      Forces use of x3f-tools based code for Foveon processing if LibRaw
      compiled with demosaic-pack-GPL2 (and does nothing if LibRaw compiled
      without this pack).
      New flag -disadcf added to dcraw_emu sample to use this flag.
    - LibRaw do not calls exit() on broken Foveon files.

* API/ABI changed, so all code using LibRaw should be recompiled.

* LibRaw 0.16.0-Alpha3

2013-10-16 Alex Tutubalin <lexa@lexa.ru>
  * Support for new cameras:
    Canon S120 (preliminary color data), G16

* Image dimensions table for Foveon cameras (only if
    non-GPL2 foveon decoder used)

* Fixed memory leak in x3f-tools code (new Foveon decoder)
  * Fixed DHT-demosaic incompatibility with MS VisualStudio in OpenMP directives
  * Additional image size checks.

* Support for Foveon sensor based on X3F code by Roland Karlsson
    BSD-like license, so included in main LibRaw code.
    No 'foveon interpolation', so no way to get good colors from
    old Sigma cameras (SD9, SD14, Polaroid x530). For modern Foveon cameras
    one may try to create ICC profile (not supplied).

TODO: thumbnail extraction, fast cancellation

Old foveon_*_load_raw (from dcraw) code is used if compiled with
    LIBRAW_DEMOSAIC_PACK_GPL2

* Fixed crash in raw decoding if raw_width/raw_height is
          less than resulting image width/height.

* imgdata.sizes.flip is set from user_flip only on
          postprocessing and/or adjust_sizes_info_only()

* Fixed buffer overrun for some LJPEG-compressed files

* Most of LibRaw_datastream function bodies are moved to
          separate source file

* LibRaw_windows_datastream is merged to main sourcetree

* LibRaw 0.14.0-Alpha5

2011-08-11 Alex Tutubalin <lexa@lexa.ru>
        * Imported dcraw 9.10 (1.444), support for new cameras added:
          ARRIRAW format, Canon SX30 IS, Leica D-LUX 5 and V-LUX2,
          Olympus E-P3, Panasonic G3 and GF3, Sony NEX-C3 and SLT-A35

* Support for RedOne digital movie cameras (R3D format).
          To enable this support you should:
           + install libjasper JPEG2000 support library

+ compile LibRaw with -DUSE_JASPER compiler switch (./configure
             will do it for you)

+ If you use own LibRaw_datastream implementation, you should
             implement make_jas_stream() call for your datastream. See
             bottom of src/libraw_cxx.cpp for  implementations in datafile
             and mem-buffer LibRaw streams.

* Bugfix: green matching is turned off if output image is shrinked
          due to wavelet filtering or aberration correction.

* fixed open_file()/adjust_sizes_info_only() code path

* Removed imgdata.sizes.bottom_margin and right_margin data fields
          use imgdata.sizes.raw_width - width - left_margin to get right one,
          the same with bottom_margin.

* minor ./configure cleanup

* Qmake files and Visual Studio Project files are updated.

* New version check macros:
          For use at runtime checks:
           LIBRAW_RUNTIME_CHECK_VERSION_EXACT() - checks  that runtime
            major/minor version numbers are same with compile-time values.

LIBRAW_RUNTIME_CHECK_VERSION_NOTLESS() - checks that runtime
            version is not less that compile-time one.

For use at compile-time in preprocessor directives:
           LIBRAW_COMPILE_CHECK_VERSION_EXACT(major,minor) - Compile-time
            check that LibRaw version is exact major.minor.

LIBRAW_COMPILE_CHECK_VERSION_NOTLESS(major,minor) - Compile-time
            check that version is not less than major.minor.

* all client code should be recompiled due to internals change.

* LibRaw 0.14.0-Alpha4

2011-07-19 Alex Tutubalin <lexa@lexa.ru>
        * New sample samples/postprocessing_benchmark.cpp
          This sample measures postprocessing speed.
          All demosaic methods, averaged white balance, median
          filtering, wavelet filtration, highlight recovery, and
          cropping are supported.

* Removed LibRaw::rotate_fuji_raw() call and corresponding C-API call.

* The LibRaw::adjust_sizes_info_only() call may be called repeated
          and mixed with dcraw_process() call.

* Postprocessing speedup and optimization, especially if cropping set.

* Cropping works for FujiCCD raws. For the technical reasons, the position
          of top-left corner of crop area will be rounded to the nearest
          multiple of 4 (the corner is shifted top-left).

* LibRaw 0.14.0-Alpha3

2011-07-15 Alex Tutubalin <lexa@lexa.ru>
        * imported cropping code from 0.13 branch

2011-07-12 Alex Tutubalin <lexa@lexa.ru>
        * samples/multirender_test - check for different clip settings

2011-07-11 Alex Tutubalin <lexa@lexa.ru>
        * New call LibRaw::free_image(), deallocates imgdata.image buffer.
          Use this call if current postprocessing results are not
          needed, but it is to early to call recycle() because
          dcraw_process() may be called later.

* New C-API calls
          libraw_raw2image() - C API for LibRaw::raw2image()
          libraw_free_image() - C API for LibRaw::free_image()
          libraw_get_decoder_info() - C API for LibRaw::get_decoder_info()

* Bugfix: change of params.user_flip aftee open()/unpack()
          calls should work.

* LibRaw 0.14.0-Alpha2

2011-07-10 Alex Tutubalin <lexa@lexa.ru>
        * Multiple rendering (LibRaw::dcraw_process() calls) allowed
          without re-opening RAW file thrfough the sequence of open()/unpack()
          calls.
          You should be able to change any processing parameters (except
          shot_select parameter) between dcraw_process() calls.

+ New sample in samples/multirender_test.cpp: renders data 4 times:
            in half and full modes with different white balance settings.

+ Unprocessed RAW data is stored in separate data buffer:
            (2 bytes per pixel for all Bayer-pattern images,
            8 bytes per pixel for Foveon, sRAW, and other full-color raw
            formats), so now LibRaw uses 25% more memory for full processing of
            most common Bayer images; while for just unpack memory is reduced
            4 times.

+ New call LibRaw::raw2image() fills imgdata.image array
            with fresh copy of data.
            There is no need to call raw2image() separately if you use
            dcraw_process() or dcraw_document_mode_processing() calls.

+ New call LibRaw::get_decoder_info() to determine raw data
            storage layout. See samples/unprocessed_raw.cpp for an example
            of how to use it.

If your code uses usual open()/unpack()/dcraw_process() call
        sequence, then NOTHING CHANGED: your program should produce same
        results. For interactive programs you may skip open()/unpack()
        calls after adjusting processing parameters, so user should see
        image refreshed much faster.

If your code uses raw data (open+unpack calls), you need to call
        LibRaw::raw2image(), and imgdata.image will contain same bitmap
        as in LibRaw 0.13.x

If you code uses access to masked borders data, you need to
        rewrite it. See samples/unprocessed_raw.cpp as a sample.

Unfortunately, documentation is untouched yet. This problem will be
        fixed in next Alpha release.

Other changes:

* No separate imgdata.masked_pixels buffers, Bayer raw formats are read
          to buffer with borders. So, no ugly add_masked_border_to_bitmap()
          call.

* No filtering_mode parameter. Raw tone curve is applied
          at unpack() stage; zero pixels removed on postprocessing stage.

* unprocessed_raw and 4colors samples are adjusted to use
          new RAW data storage layout.

* all client code should be recompiled due to internals change.

* LibRaw 0.14.0-Alpha1

2011-07-03 Alex Tutubalin <lexa@lexa.ru>
        * Cosmetic cleanup in Libraw_memmgr code

* Permit OpenMP support on MS VS2008

* More general mem_image interface:
          + New call get_mem_image_format returns bitmap size and bit depth
          + New call copy_mem_image can copy bitmap into buffer with
            different color order (RGB/BGR) and line stride
          + dcraw_make_mem_image() uses calls mentioned above
          + see documentation for info on these function parameters.

* libraw/librawwindows.h implements LibRaw_datastream class based
          on Windows memory mapped files.Win32/64-only
          Thanks to Linc Brookes.

* Fixed parallel make errors in configure/Makefile.am

               filters by Paul Lee
          3) GPL3 demosaic pack with AMaZe interpolation  by Emil Martinec

See more details in README.demosaic-packs

* Current implementation of dcraw_emu sample allows only selection
          of demosaic method (via -q) options. All other parameters change
          will be implemented later.

* LibRaw 0.12-alpha1

           * fixed comment style in libraw_datastream.h
           * LibRaw 0.11-Beta6

2010-10-15 Alex Tutubalin <lexa@lexa.ru>

* New changes to I/O layer. Three LibRaw_*datastream clasees are
             exists:
               + LibRaw_buffer_datastream - buffer reaging
               + LibRaw_file_datastream - file reading using iostreams
                 (large files are no supported on some systems)
               + LibRaw_bigfile_datastream - FILE*-based file I/O

*  file/bigfile_datastream is selected automatically by
              LibRaw::open_file based on input file size.
              By default, files larger than 250Mb are opened using
              bigfile interface, you may change this behaviour
              by using second optional parameter of open_file()

* There is no way to use default parameter values in C API,
             so new call libraw_open_file_ex added with two parameters
             (file name and minimal file size for bigfile_datastream use).

* all client code should be recompiled due to internals change.

* All LibRaw_abstract_datastream functions are virtual again. You may
             (again) use your own I/O layer.

* new -d key for dcraw_emu sample: print timings of processing stages

* simple_dcraw sample simplified: no mmap code

* LibRaw 0.11-Beta5

2010-10-08 Alex Tutubalin <lexa@lexa.ru>
           * Fixed bug in exception handling in OpenMP sections in
             AHD interpolation code.

* LibRaw_datastreams are now C++ iostreams based instead of old
             plain FILE* calls.
             LibRaw::open_file() in multithreaded programs are WAY faster
             on many OSes (Linux, Windows, MacOSX) because of no extra locks.

* all client code should be recompiled due to internals change.

* LibRaw 0.11-Beta4

2010-10-01 Alex Tutubalin <lexa@lexa.ru>
           * Fixed bug in LibRaw::dcraw_process() code: for half_size
             processing, params.four_color_rgb was set to 1 internally
             and not returned back after postprocessing.

* Several Visual Studio 2003 compatibility fixes

* AHD interpolation refactored. Now it is about 10% faster than
              dcraw in single-process mode and up to 1.5 times faster on
              4-core and OpenMP (total execution time counted, not AHD itself)
              Thanks to Adam Hooper

* LibRaw 0.11-Beta3

2010-09-07 Alex Tutubalin <lexa@lexa.ru>
           * Phase One files: LibRaw::unpack() sets colordata.black to
             approximately correct value.

* Fixed minor error in setting colordata.maximum value
             for Phase One files.

* LibRaw::subtract_black() sets colordata.black and
             colordata.cblack[] to zero to preserve data integrity.

* LibRaw 0.11-Beta2

2010-09-04 Alex Tutubalin <lexa@lexa.ru>

* It is now possible to crop output image on postprocessing
            stage (dcraw_process). Coordinates and size of the output box
            are set via imgdata.params.cropbox[4] parameter. Look into
            LibRaw documentation for more details.

+ New fatal error code LIBRAW_BAD_CROP

+ New dcraw_emu sample command line switch: -B x y w h
                (sets cropbox)

Thanks to Patrick and Jan.

* Processing pipeline has changed: the black level is subtracted
              from data on postprocessing stage either automatically
              (on dcraw_process() stage) or by special LibRaw API call:

+ New API calls:  LibRaw::subtract_black() (C++ API) and
                 libraw_subtract_black (C API).
                 If you use dcraw_process() or dcraw_document_mode_processing()
                 calls YOU DON'T NEED to call subtract_black() directly.

+ The raw preprocessing mode LIBRAW_FILTERING_NOBLACKS
                 is deprecated and removed from LibRaw.

* New ./configure script.
               Use ./configure -h for usage details.
               Thanks to Siddhesh Poyarekar

* New API cals static LibRaw::dcraw_clear_mem() (C++ API)
               and libraw_dcraw_clear_mem(..) (C API).
               This calls are used to free memory, allocated by
               dcraw_make_mem_image() and dcraw_make_mem_thumb() instead
               of free() call.

In some cases LibRaw and calling process have different
               memory managers, so free() of make_mem_image() data
               results to program crash (especially in Win32/VisualStudio
               environment).

* LibRaw::free() is now private instead of public (again).

* Minor changes and bugfixes:

+ Memory allocation exceptions (std::bad_alloc) are caught,
                 so LibRaw API calls will return reasonable error codes
                 instead of C++ exception (possibly unhandled).
                 This problem is very unlikely to see in wild: if application
                 cannot allocate small data for internal structure, it will
                 always fail on allocation for RAW image data.

+ WIN32/VisualStudio 2008/2010: fopen,fscanf and sscanf calls
                 in Libraw_datastream code are changed to *_s (secure) ones.

+ Debug print removed from fatal error handler.

+ Mmaped I/O for dcraw_emu sample is turned on via -E switch
                 now (because old -B switch is used for setting cropbox).

* New postprocessing parameter params.adjust_maximum_thr
             This parameter replaces LibRaw::adjust_maximum(), but more flexible

New licensing:

* Triple licensing (selected by LibRaw user):

+ LGPL 2.1 (http://www.gnu.org/licenses/lgpl-2.1.html)
              + CDDL 1.0 (http://www.opensource.org/licenses/cddl1.txt)
              + LibRaw Software License (27 March 2010 version)
               (http://www.libraw.org/data/LICENSE.LibRaw.pdf)

* There is no separate LibRaw-Lite and LibRaw-Commercial versions,
             only single LibRaw.
             Current LibRaw-Lite and LibRaw-Commercial users should switch
             to LibRaw without loss of functionality.
             It is possible to change licensig too (e.g. from LGPL to CDDL
             for LibRaw-Lite users and from LibRaw License to LGPL or CDDL
             for LibRaw-Commercial users).

* No Foveon support :(
             It is not possible to get good color from Foveon sensors with
             *any* converter. So, there is no need to support these cameras.
             Dcraw's Foveon-processing code is too strict licensed (GPL),
             so we choose to drop it.

New Features:

* New data field  colordata.channel_maximum[4] - per channel data
            maximum (calculated for most cameras, 0 for others).

* New call LibRaw::adjust_maximum() (and libraw_adjust_maximum() in C API).
             This call changes hardcoded colordata.maximum value to calculated
             at unpack stage. This helps suppress false color in highlights
             (magenta clouds and so).

* New command line parameter -c for dcraw_emu sample. Calls adjust_maximum()
             for each processed file.

* all client code should be recompiled due to structures size
             change

* LibRaw 0.9.0-Beta1

* Samples: dcraw_emu and mem_image samples supports new dcraw
              16bit/gamma semantics:

           * Black level was not calculated for Canon RAWs in
             some filtering modes

* 4channels sample prints calculated black level
             (scaled if autoscaling used).
             Also output file names for this sample now includes

* LibRaw 0.7.0-Beta2

2009-02-09 Alex Tutubalin <lexa@lexa.ru>

           * Fixed bug in external jpeg metadata reading code.

* Cleaned some C++ warnings

* dcraw 8.91/1.418 imported
             + Hasselblad V96C support

* You need to clean and recompile client code which
             uses LibRaw_*_datastream classes.

* LibRaw 0.7.0-Alpha6

2009-01-30  Alex Tutubalin <lexa@lexa.ru>

* New data input framework is created. It is possible now to
             easyly implement your own data input interface for LibRaw
             (e.g. for reading RAW data from network data stream)

* All older programs using previous LibRaw versions are
	     compatible at source code level.

* LibRaw can read RAW data from memory buffer via
             new LibRaw::open_buffer() API call (implemented on top of
             new input framework).
             This call used in sample application dcraw_emu and simple_dcraw
             (with -B command-line switch) to test new API.

* Error handling callback functions now can be called with
             NULL filename passed (if underlying data stream object
             does not know file name).
             So, client error handling callbacks should work with NULL
             filename.

* All client code should be recompiled

* Imported dcraw 8.90/1.417:
              + Support for loading White Balance data from
                Sony ARW files edited with Sony IDC software.

* LibRaw 0.7.0-Alpha5

2009-01-17 Alex Tutubalin <lexa@lexa.ru>
           * Raw filtering mode LIBRAW_FILTERING_NOPOSTPROCESS has renamed
            to LIBRAW_FILTERING_NORAWCURVE for better reflect its purpose.
            This filtering_mode bit turns off tone curve applying on
            RAW data on bayer-pattern cameras with raw tone curve:
              + Adobe DNG (only RAW with bayer pattern)
              + Nikon compressed NEF
              + Some Kodak cameras
              + Sony A700/A900 (tone curve applied to 8-bit raws)

* unprocessed_raw sample: added command-line key -N, this key
             turns on LIBRAW_FILTERING_NORAWCURVE filtering mode.

* New scheme of Fuji RAW processing (introduced in 0.7-Alpha3)
             supports DNG files generated from Fuji RAF.

* Imported dcraw 8.90/1.416:
              + better support for Samsung S85
              + fixed possible integer overflow in wavelet denoising code

* LibRaw 0.7.0-Alpha4

           * Black mask extraction supported for all files with bayer data
            (one component per pixel). Black mask data not available
            for multi-component data (Foveon, Canon sRAW, Sinar 4-shot,
            Kodak YCC/YRGB).

* Black level subtraction can be turned off for all bayer
            cameras (added support for PhaseOne backs).

* Fujifilm camera processing model changed:
              + RAW data is extracted without 45-degree rotation
              + dcraw-compatible rotation is performed on postptocessing stage
              + it is possible to rotate RAW data without postprocessing
                by LibRaw::rotate_fuji_raw() call.

* New filtering mode setting: LIBRAW_FILTERING_NOPOSTPROCESS
             This bits turns off RAW tone curve processing based on tone curve
             readed from RAW metadata.
             This mode supported only for PhaseOne backs now (to be supported
             on all relevant cameras in nearest future releases)

* Black level data (got from RAW data) are stored for PhaseOne backs.

* Black level subtraction bug (derived from dcraw) fixed
             for PhaseOne files.

* Fixed processing of -s parameter for dcraw_emu sample

* Parameter  -s N (select shot number) added to
             unprocessed_raw sample.

* Imported dcraw 8.90/1.414:
              + changes in QuickTake 100 metadata processing
              + changes in external jpeg processing code
              + Samsung S85 support

* All client code should be recompiled

* LibRaw 0.7.0-Alpha3 released

2009-01-10 Alex Tutubalin <lexa@lexa.ru>
           * Fixed bug in add_masked_borders: crash if output dimensions
            is already larger than raw dimensions
            * Fixed out of bounds in samples/unprocessed_raw.cpp for files
            with non-square pixels

* LibRaw 0.7.0-Alpha2 released

2009-01-08 Alex Tutubalin <lexa@lexa.ru>
           * Fixed bug in  0.7.0-a0: black frame size has not reset,
             so in batch processing there is an error in black frame
             size for files without black frame.

* Implemented reading of black/masked pixels data for
             near all cameras with masked pixels, exclding:
              + Canon sRAW, Leaf (MOS), Sinar 4-shot - more than one
                color component in black frame (redesign of black frame
                data structures required).
              + Fuji SuperCCD: need to design right methods of extraction
                (should we rotate and resize black pixels as active ones??)

* Tested for most dSLR data formats with masked pixels: 7 of 9
              untested formats are from old P&S cameras.

* New call LibRaw::unpack_function_name() returns unpack function name
             (useful for testers only)

* New identify sample parameters (useful for test-suite builders
             to check test coverage):
                  -u - print unpack function name
                  -f - print masked frame size
             These parameters works only for identify run without -v parameter

* Imported dcraw 8.89/1.411
             + changes in Panasonic FZ50 files parsing

* LibRaw 0.7.0-Alpha1 released

2009-01-05 Alex Tutubalin <lexa@lexa.ru>
           * It is possible to turn off RAW data filtration (black level
             subtraction,              zero pixels averaging):
                + supported on all cameras except Foveon and Phase One
                + filtraction controlled by new parameter "filtering_mode"
                + it is possible to expand API by filtering procedures
                  built for specific camera model.

* Black border (masked pixels) extraction:
                + API (data structures) for storing black mask.
                + Black mask extraction supported only for limited list of
                  data formats:
                       - Canon .CRW, .CR2 (with exception of sRAW),A600, A5
                       - Adobe DNG (both converted RAW and native DNG)
                       - Nikon NEF (compressed only)
                  this list to be expanded in future LibRaw versions
           * New call add_masked_borders_to_bitmap makes full bitmap
             'masked border' + image
           * Usage sample for functionality listed above:
              samples/unprocessed_raw
           * Imported dcraw 8.89/1.410:
              + fixed bugs in Hasselblad .fff decoding
              + fixes in Imacon metadata decoding
