  • PtGrey GRAS-50S5C

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
Other
  • 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_intepolate 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
