Submitted by lexa on

LibRaw 0.22 PreRC1 is just published in our Github repository. Here are changes relative to 202502 snapshot:

Camera support

  • Canon EOS R1, EOS R5 Mark II
  • Fujifilm X-T50, GFX 100S II
  • Leica Q3 43, D-Lux8
  • Nikon Z6-III (no HE/HE* support)
  • Panasonic GH7, S9
  • Sony ZV-E10M2, UMC-R10C

Big changes/API changes

  • New implementation for Samsung V3 decoder (NX1, NX500, etc)
  • Canon AutoRotate mode detection for several cameras.
    If LIBRAW_RAWOPTIONS_CANON_CHECK_CAMERA_AUTO_ROTATION_MODE bit is set in imgdata.rawparams: for shots with AutoRotate is Off TIFF::Orientation tag wil be used for imgdata.sizes.flip (and Makernotes rotation tag for other AutoRotate modes).
    Note: AutoRotate is detected for limited set of Canon cameras, namely: EOS 6D, 5D Mark IV, 5DS, 5DS R
    To extend this list: we need specially shot samples to detect AutoRotate field location in metadata. Contact us for details if you need to add your camera to list and have such camera on hands
  • New rawoptions/processing flag for DNG processing if compiled with Adobe DNG SDK:
    LIBRAW_RAWOPTIONS_DNG_STAGE23_IFPRESENT_JPGJXL
    Similar to LIBRAW_RAWOPTIONS_DNG_STAGE2_IFPRESENT,LIBRAW_RAWOPTIONS_DNG_STAGE3_IFPRESENT flags but applied to JPEG/JPEG-XL compressed images only:
    If OpcodeList2/OpcodeList3 tags are present in the input DNG file, these tags will be processed via Adobe DNG SDK, producing corrected (de-bayered) image.
  • LibRaw::adjust_to_raw_inset_crop exposed via C-API call: libraw_adjust_to_raw_inset_crop(libraw_data_t *lr, unsigned mask, float maxcrop); Note: default maxcrop value for C++ API is 0.55f
  • DNG OpcodeList1/2/3: opcode list(s) are read (as is) into imgdata.color.dng_levels.rawopcodes[3]

Minor fixes/improvemtns

  • Fixed issue 712: mistype in MIN/MAX that loosens camera WB preset checks
  • Updated libraw_types.h to fix calling C++ files in external C -- main includes cannot be in extern C for the library to correctly compile under Swift Modules. This small change lets the compiler finish when compiling the library inside a module.
  • Read known parts of the X3F 4.X (Quattro) header
  • Rollei loader: more realistic limits
  • Additional metadata checks in PhaseOne files processing
  • Multiple minor fixes to better handling of specially crafted files
  • Fixed regression in Fujufilm S6000/S6500 support
  • Support for 4-color lossy-compressed DNG files
  • Improved damaged/incorrect/modified CR3 files handling
  • Colordata updated for several Fujifilm cameras
  • Improved byte order detection for PowerPC
  • NOMINMAX defined before #include winsock2.h in LibRaw public header to not provide min/max macros to the code that includes libraw.h
