LibRaw 0.16-Release changes (since 0.15.x):
  • Support for new cameras:
    • Baumer TXG14

  • Support for Foveon sensor based on X3F code by Roland Karlsson

    BSD-like license, so included in main LibRaw code. No 'foveon intepolation', 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).

    • 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.
API Changes:
  • New parameters in imgdata.params:

    - imgdata.params.no_interpolation - disables interpolation step in LibRaw::dcraw_process() call.

    - imgdata.params.no_auto_scale - disables call to scale_colors() in LibRaw::dcraw_process() call.

    - imgdata.params.sraw_ycc - disables Canon sRAW YCbCr to RGB conversion in LibRaw::unpack() call (use for RAW analyzers

  • New Fuji X-Trans handling: - imgdata.iparams.filters value is now 9 for Fuji X-Trans (instead of 2) - imgdata.iparams.xtrans[6][6] matrix contains row/col to color mapping for Fuji X-Trans sensor.
  • LibRaw::setCancelFlag() - use for fast decoder termination
  • LibRaw_abstract_datastream::make_byte_buffer() call is not needed more.
Other Changes
  • New demosaic code: DHT Demosaic by Anton Petrusevich

    Set params.user_qual=11 to use.

  • New demosaic code: Modified AHD Demosaic by Anton Petrusevich

    Set params.user_qual=12 to use.

  • New C-API call libraw_COLOR(libraw_data_t *t, int row,int col) (so LibRaw::COLOR(row,col) exposed to C-API users)
  • Better EXIF parsing:
    • ISO values for new Nikon cameras (D4, D800)
    • black level extraction for Nikon D5300
    • correct Olympus color data conversion
    • 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
  • Removed faster lossless jpeg decoder ported from RawSpeed library some years ago. Build LibRaw with RawSpeed to get fast decoding.
  • Canon EOS model name normalized by unique ID table
  • DNG without Compression tag assumed uncompressed
  • Backported 0.15.4 input data checks
  • Support for CMake builds
