LibRaw 0.14.1 (11-10-2011)

• Imported dcraw 9.11/1.445:
  • Support for new cameras added: Fujifilm F600EXR, Nikon P7100, Olympus E-PL3 and E-PM1, Panasonic DMC-FZ150, Sony NEX-5N, A65 and A77.
  • Updated color data for: Olympus E-P3, Panasonic G3 and GF3, PhaseOne H25, P40 and P65, Sony NEX-C3, NEX-5, NEX-3, A35 and A55.
  • Support for dark frame extraction on Sony cameras.
• DCB demosaicing: reserving 6 pixels instead of 3 to suppress colored image frame.

LibRaw 0.14.0 (21-09-2011)

• Multiple rendering (LibRaw::dcraw_process() calls) allowed without re-opening RAW file thrfough the sequence of open()/unpack() calls.
  You should be able to change any processing parameters (except shot_select parameter) between dcraw_process() calls.
  • New sample in samples/multirender_test.cpp: renders data 4 times: in half and full modes with different white balance settings.
  • Unprocessed RAW data is stored in separate data buffer: (2 bytes per pixel for all Bayer-pattern images, 8 bytes per pixel for Foveon, sRAW, and other full-color raw formats), so now LibRaw uses 25% more memory for full processing of most common Bayer images; while for just unpack memory is reduced 4 times.
  • New call LibRaw::raw2image() fills imgdata.image array with fresh copy of data. There is no need to call raw2image() separately if you use dcraw_process() or dcraw_document_mode_processing() calls.
  • New call LibRaw::get_decoder_info() to determine raw data storage layout. See samples/unprocessed_raw.cpp for an example of how to use it.
  • New call LibRaw::free_image(), deallocates imgdata.image buffer. Use this call if current postprocessing results are not needed, but it is to early to call recycle() because dcraw_process() may be called later.
  • New C-API calls libraw_raw2image() - C API for LibRaw::raw2image() libraw_free_image() - C API for LibRaw::free_image() libraw_get_decoder_info() - C API for LibRaw::get_decoder_info()

  If your code uses usual open()/unpack()/dcraw_process() call sequence, then NOTHING CHANGED: your program should produce same results. For interactive programs you may skip open()/unpack() calls after adjusting processing parameters, so user should see image refreshed much faster.

  If your code uses raw data (open+unpack calls), you need to call LibRaw::raw2image(), and imgdata.image will contain same bitmap as in LibRaw 0.13.x

  If you code uses access to masked borders data, you need to rewrite it. See samples/unprocessed_raw.cpp as a sample.

• Other changes:
  • No separate imgdata.masked_pixels buffers, Bayer raw formats are read to buffer with borders. So, no ugly add_masked_border_to_bitmap() call.
  • No filtering_mode parameter. Raw tone curve is applied at unpack() stage; zero pixels removed on postprocesing stage.
  • unprocessed_raw and 4colors samples are adjusted to use new RAW data storage layout.
  • OpenMP speedup of postprocessing steps (up to 50% for half mode and 4-core machine)
  • Most of LibRaw_datastream function bodies are moved to separate source file
  • LibRaw_windows_datastream is merged to main source tree
  • Imported dcraw 9.10 (1.444), support for new cameras added: ARRIRAW format, Canon SX30 IS, Leica D-LUX 5 and V-LUX2, Olympus E-P3, Panasonic G3 and GF3, Sony NEX-C3 and SLT-A35
  • Support for RedOne digital movie cameras (R3D format). To enable this support you need to:
    • install libjasper JPEG2000 support library
    • compile LibRaw with -DUSE_JASPER compiler switch (./configure will do it for you)
    • If you use own LibRaw_datastream implementation, you should implement make_jas_stream() call for your datastream. See bottom of src/libraw_cxx.cpp for implementations in datafile and mem-buffer LibRaw streams.
  • Bugfix: green matching is turned off if output image is shrinked due to wavelet filtering or aberration correction.
  • Removed imgdata.sizes.bottom_margin and right_margin data fields use imgdata.sizes.raw_width - width - left_margin to get right one, the same with bottom_margin.
  • Minor ./configure cleanup
  • Qmake files and Visual Studio Project files are updated.
  • New version check macroses.
  • Documentation changed to reflect 0.14 changes.
  • Removed LibRaw::rotate_fuji_raw() call and corresponding C-API call.
  • The LibRaw::adjust_sizes_info_only() call may be called repeated and mixed with dcraw_process() calls.
  • Postprocessing speedup and optimization, especially if cropping set.
  • Cropping works for FujiCCD raws. For the technical reasons, the position of top-left corner of crop area will be rounded to the nearest multiple of 4 (the corner is shifted top-left).
  • New sample samples/postprocessing_benchmark.cpp This sample measures postprocessing speed. All demosaic methods, averaged white balance, median filtering, wavelet filtration, highlight recovery, and cropping are supported.
• all client code should be recompiled due to internals change.

LibRaw 0.13.8 (2011-08-10)

• Imported dcraw 9.10 (1.444), support for new cameras added: ARRIRAW format, Canon SX30 IS, Leica D-LUX 5 and V-LUX2, Olympus E-P3, Panasonic G3 and GF3, Sony NEX-C3 and SLT-A35
• Bugfix: green matching is turned off if output image is shrinked due to wavelet filtering or aberration correction.

LibRaw 0.13.7 (2011-07-15)

• Changes in cropping code:
  • cropping is now works for Fuji files (instead of crash)
  • bad pixels map and dark frame subtraction is turned off if cropping enabled
  • for technical reasons, coordinates of top-left corner of crop box are rounded to multiple of 4 for Fuji files.
• ./configure stuff fixes:
  • install static libraries only when --enable-static is set
  • compiled samples are dynamically linked if shared library not disabled.
• OpenMP enabled for Visual Studio 2008 SP1+, but not for RTM

LibRaw 0.13.6 (2011-07-03)

• Cosmetic cleanup in Libraw_memmgr code
• Permit OpenMP support on MS VS2008

  • New call copy_mem_image can copy bitmap into buffer with different color order (RGB/BGR) and line stride
  • dcraw_make_mem_image() uses calls mentioned above
  • see documentation for info on these function parameters.
