2024-02-27openjpeg.h: make sure to include opj_config.h (fixes #1514)Even Rouault
It was previously included by openjpeg.h
2023-09-24Require `stdint.h` & `inttypes.h`mayeut
With #1450 which goes with 480cc9d49775d018c19ce0e01f6be27858d63d39 "Remove support for non-C99 compilers (like VS2010) that don't support snprintf()", support for MSVC versions prior to vs2015 is dropped: https://stackoverflow.com/questions/2915672/snprintf-and-visual-studio-2010 This means that all supported MSVC versions do have `stdint.h` & `inttypes.h` now. For non windows platforms, those headers were already mandatory. Make them mandatory for all builds.

2022-02-10Add support for partial bitstream decoding (#1407) (fixes #715)Robert Gabriel Jakabosky
Add a -allow-partial option to opj_decompress utility and a opj_decoder_set_strict_mode() option to the API Co-authored-by: Chris Hafey <chafey@gmail.com>
2022-01-23opj_encoder_set_extra_options(): add a GUARD_BITS=value optionEven Rouault
and add a -GuardBits option to opj_compress. The recently-released SMPTE DCP Bv2.1 Application Profile (link below) says that the number of guard bits in the QCD marker shall be 1 for 2K content and 2 for 4K content. This change allows the number of guard bits to be configured, so that users of openjpeg have the control they need to meet the specification. https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=9161348 This is an alternative implementation of https://github.com/uclouvain/openjpeg/pull/1388 that keeps ABI unchanged.

2021-10-21API: deprecate 'bpp' member in favor of 'prec'Even Rouault
in opj_image_comp and opj_image_comptparm structures. bpp was redundant with prec, and almost never set by the library, except by opj_image_create(). This change should hopefully not impact existing, working, users of the API, which should already have used prec to get things working. Fixes #1379
2021-06-07Add support for enabling generation of TLM markers in encoderEven Rouault
Support was already there, but restricted to Cinema and IMF profiles, and 255 tiles * Add -TLM switch added to opj_compress * Make opj_encoder_set_extra_options() function accept a TLM=YES option.

2020-05-20Add multithreading support in the T1 (entropy phase) encoderEven Rouault
- API wise, opj_codec_set_threads() can be used on the encoding side - opj_compress has a -threads switch similar to opj_uncompress
2020-04-21Add support for generation of PLT markers in encoderEven Rouault
* -PLT switch added to opj_compress * Add a opj_encoder_set_extra_options() function that accepts a PLT=YES option, and could be expanded later for other uses. ------- Testing with a Sentinel2 10m band, T36JTT_20160914T074612_B02.jp2, coming from S2A_MSIL1C_20160914T074612_N0204_R135_T36JTT_20160914T081456.SAFE Decompress it to TIFF: ``` opj_uncompress -i T36JTT_20160914T074612_B02.jp2 -o T36JTT_20160914T074612_B02.tif ``` Recompress it with similar parameters as original: ``` opj_compress -n 5 -c [256,256],[256,256],[256,256],[256,256],[256,256] -t 1024,1024 -PLT -i T36JTT_20160914T074612_B02.tif -o T36JTT_20160914T074612_B02_PLT.jp2 ``` Dump codestream detail with GDAL dump_jp2.py utility (https://github.com/OSGeo/gdal/blob/master/gdal/swig/python/samples/dump_jp2.py) ``` python dump_jp2.py T36JTT_20160914T074612_B02.jp2 > /tmp/dump_sentinel2_ori.txt python dump_jp2.py T36JTT_20160914T074612_B02_PLT.jp2 > /tmp/dump_sentinel2_openjpeg_plt.txt ``` The diff between both show very similar structure, and identical number of packets in PLT markers Now testing with Kakadu (KDU803_Demo_Apps_for_Linux-x86-64_200210) Full file decompression: ``` kdu_expand -i T36JTT_20160914T074612_B02_PLT.jp2 -o tmp.tif Consumed 121 tile-part(s) from a total of 121 tile(s).

2017-09-19Add capability to decode only a subset of all components of an image.Even Rouault
This adds a opj_set_decoded_components(opj_codec_t *p_codec, OPJ_UINT32 numcomps, const OPJ_UINT32* comps_indices) function, and equivalent "opj_decompress -c compno[,compno]*" option. When specified, neither the MCT transform nor JP2 channel transformations will be applied. Tests added for various combinations of whole image vs tiled-based decoding, full or reduced resolution, use of decode area or not.

pool to tcd level By default, only the main thread is used. If opj_codec_set_threads() is not used, but the OPJ_NUM_THREADS environment variable is set, its value will be used to initialize the number of threads. The value can be either an integer number, or "ALL_CPUS". If OPJ_NUM_THREADS is set and this function is called, this function will override the behaviour of the environment variable.
