    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
    • Hasselblad BaseISO and Gain extracted into makernotes.hasselblad
    • Canon multishot params extracted into
    • 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
  • 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
    • pow64f renamed to libraw_pow64f
  • Bugs fixed:
    • COLOR(r,c) works correctly on X-Trans files
  • Security fixes:

      • leaf_hdr_load_raw: check for image pointer for demosaiced raw
      • NOKIARAW parser: check image dimensions readed from file
      • quicktake_100_load_raw: check width/height limits
    • Secunia #79000: Credit: Laurent Delosieres, Secunia Research at Flexera
      • All legacy (RGB raw) image loaders checks for imgdata.image is not NULL
      • kodak_radc_load_raw: check image size before processing
      • legacy memory allocator: allocate max(widh,raw_width)*max(height,raw_height)
    • Secunia #76000:
      • Fixed fuji_width handling if file is neither fuji nor DNG
      • Fixed xtrans interpolate for broken xtrans pattern
      • Fixed panasonic decoder
    • Other fixes:
      • Checks for width+left_margin/height+top_margin not larger than 64k
      • LIBRAW_MAX_ALLOC_MB define limits maximum image/raw_image allocation (default is 2048 so 2Gb per array)
      • LibRaw::read_shorts item count is now unsigned
      • Fixed possible out of bound access in Kodak 65000 loader
      • CVE-2017-14348: Fix for possible heap overrun in Canon makernotes parser Credit: Henri Salo from Nixu Corporation
      • Fix for CVE-2017-13735
      • CVE-2017-14265: Additional check for X-Trans CFA pattern data
      • Fixed several errors (Secunia advisory SA75000)
      • ACES colorspace output option included in dcraw_emu help page
      • Avoided possible 32-bit overflows in Sony metadata parser
      • Phase One flat field code called even for half-size
