LibRaw 0.11 Beta4

LibRaw 0.11 Beta4 is avaliable for download and testing

Changes are:

  • Fixed bug in exception throwing in OpenMP AHD code.
  • LibRaw I/O is now C++ iostreams based instead of old FILE* interface. So multithreaded apps using LibRaw are about 1.5 times faster on unpack() stage under Linux and up to 3x times faster under Win32.

Feel free to contact us if you have bug reports or suggestions.

LibRaw 0.11 Beta3

LibRaw 0.11 Beta3 is avaliable for download

Changes list (from 0.11 Beta2):

  • Fixed bug in half-size postprocessing: the params.four_color_rgb was set to 1 internally and not restored after postprocessing.
  • AHD interpolation is refactored and now works much faster, especially with OpenMP on multicore systems.
  • Some minor changes to make Visual Studio 2003 more happy.

Look into version's changelog for more details.

LibRaw 0.11 Beta2

All-new LibRaw 0.11 Beta2 is avaliable for developers

Changes list, in short (from 0.10.0):

  • It is now possible to crop output image on postprocessing stage (dcraw_process). Coordinates and size of the output box are set via imgdata.params.cropbox[4] parameter. Look into LibRaw documentation for more details.
  • Processing pipeline has changed: the black level is subtracted from data on postprocessing stage either automatically (on dcraw_process() stage) or by special LibRaw API call:
  • New ./configure script. Use ./configure -h for usage details.
  • New API cals static LibRaw::dcraw_clear_mem() (C++ API) and libraw_dcraw_clear_mem(..) (C API). This calls are used to free memory, allocated by dcraw_make_mem_image() and dcraw_make_mem_thumb() instead of free() call.
  • Many minor changes and bugfixes:
  • all client code should be recompiled due to structures size change
