API changes

  1. dcraw_process() can now be called several times with different parameters
    without re-opening and unpacking the file for second and consecutive
    calls to dcraw_process
  2. Deleted (nobody uses those)
    • LibRaw::dcraw_document_mode_processing (and respective C-API)
    • imgdata.color.color_flags data field
  3. LibRaw::unpack() now decodes data into different buffers, the buffer
    depends on the raw data type
    • imgdata.rawdata.raw_image - 1 color component per pixel,
      for b/w and Bayer type sensors
    • imgdata.rawdata.color3_image - 3 color components per pixel,
      sRAW/mRAW files, RawSpeed decoding
    • imgdata.rawdata.color4_image - 4 components per pixel, the 4th
      component can be void
  4. Support for compiling with RawSpeed library, http://rawstudio.org/blog/?p=800
    details are in README.RawSpeed
  5. Suppression of banding
  6. New API calls
    • recycle_datastream(),
    • open_file(wchar_t*) (Win32)

LibRaw 0.15.0-Beta4

Submitted by lexa on

LibRaw 0.15 Beta4 changes:

  • Fixed possible buffer overrun when RawSpeed library used
  • Added new C++ API Call LibRaw::recycle_datastream(), C API call
    libraw_recycle_datastream() and new errorcode LIBRAW_INPUT_CLOSED
    for unpack/unpack_thumb() calls.

    These new API calls may be used to free file handle (and associated
    file buffer) if your application will not call unpack*() on this
    LibRaw handle, so file may be unlocked.

  • Support for Imacon Ixpress 39Mpix Multi-shot files
