This switches to the new major release.
The most significant change of this version is multiple rendering
of same RAW data without re-opening RAW file.
So, it is possible to implement near-realtime preview of entire image in
half-resolution mode and realtime preview of selected area (e.g. around
mouse pointer position) in full-resolution mode.
+Support for more cameras
Upstream changes:
LibRaw 0.14.2 (19-10-2011)
Fixed bug in Canon 1D and 1Ds files decoding.
New decoder information bit DECODER_HASRAWCURVE
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 is a library for reading RAW files obtained from digital photo
cameras (CRW/CR2, NEF, RAF, DNG, and others).
LibRaw is based on the source codes of the dcraw utility, where part of
drawbacks have already been eliminated and part will be fixed in future.
The users of the library are provided with API to be built into their
software programs.
