== LibRaw snapshot 202110 ==
* Camera Format support:
- Sony Lossless compressed support
- Panasonic v6/12 bit
* Camera support:
DJI Mavic Air 2S
Fujifilm GFX 50S II; GFX 100S, X-E4
GoPro HERO9, HERO10 (if compiled w/ USE_GPR_SDK)
Nikon Z fc
Panasonic GH5 Mark II
Pentax K3 Mark III
Olympus E-P7
Ricoh GR IIIx
Sony A1, A7R-IIIA (ILCE-7RM3A), A7R-IVA (ILCE-7RM4A), ZV-E10
Canon EOS M50 Mark II was supported but not listed in camera list
Multiple phones tested and added to cameralist.cpp
* Support for RaspberryPi HQ camera (if compiled w/ USE_6BY9RPI)
* Improved support for RPi V1/V2 cameras:
- white balance data extraction
- color matrix extracted to imgdata.color.cmatrix to use with
use_camera_matrix.
- full-size thumbnail/preview support for JPEG+RAW files (raspistill -r)
== API-ABI changes ==
* (INCOMPATIBILITY WITH OLDER VERSIONS!!!)
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.
* 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.
* 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.
* Shared library version incremented to disallow automated upgrades (will not work because of ABI change)
== Metadata parsing improvements ==
* Olympus makernotes parsing: LiveND mode, Panorama mode tags.
* Fuji GFX100/GFX100S: PixelShift metadata extraction.
* Fuji RAF files: XMP block extraction
== Misc improvements, limits implemented, etc ==
* Canon/12-bit files: adjust color.linear_max and makernotes.canon values
to match data range.
* 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
* Compile-time raw size limits implemented:
LIBRAW_MAX_NONDNG_RAW_FILE_SIZE - max file size for non-DNG files (default: 2GB - 1 byte)
LIBRAW_MAX_DNG_RAW_FILE_SIZE - max DNG file size limit (4GB-1 if compiled w/ DNG SDK, 2GB-1 overwise)
* samples/raw-identify.cpp: -v flag documented in usage print.
* src/libraw_cxx.cpp completely removed from source tree to not confuse users.
(also all mentions are removed from Makefiles)
* clang-cl compatibility:
- defines _MSC_VER, but _forceinline is not supported
- warnings eliminated in Windows buffered datastream
* XMP block size in CR3 files limited to 1MB
* Preview block size in CR3 files limited to 100MB
* Improved Phase One Compressed defects masking, thanks to Alexey Danilchenko
* 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.
* ACES output: color conversion changed to provide D65 white point
* Fix for Canon 5D Mark II/sRAW1 incorrect camera provided crop
* RawSpeed (master): fixed bug in old Samsung/compressed decoder,
apply this patch to RawSpeed: RawSpeed/rawspeed.samsung-decoder.patch
* DCI-P3 and Rec 2020 output colorspaces
* Eliminated multiple signed/unsigned mismatch warnings (reported by gcc11)
* Fixed a typo in LIBRAW_OPTIONS_* flag names
(was LIBRAW_OPIONS, old flags names not removed due to compatibility)
== Bugfixes ==
* fixed possible 1-byte stack underrun while handling text tags with zero lengh
* Fixed wrong handling of linear DNG files created from Pentax out-of-camera DNGs

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

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 embeded 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>

* 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
* Swtiched 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.

* 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
* Fixed dcraw.c ljpeg_start possibly buffer overrun
* fixed several bugs detected by using American Fuzzy Lop
* C-API extension to support 3DLut Creator
* 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 techincal 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.
