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). Consumed 80,318,806 codestream bytes (excluding any file format) = 5.329697 bits/pel. Processed using the multi-threaded environment, with 8 parallel threads of execution ``` Partial decompresson (presumably using PLT markers): ``` kdu_expand -i T36JTT_20160914T074612_B02.jp2 -o tmp.pgm -region "{0.5,0.5},{0.01,0.01}" kdu_expand -i T36JTT_20160914T074612_B02_PLT.jp2 -o tmp2.pgm -region "{0.5,0.5},{0.01,0.01}" diff tmp.pgm tmp2.pgm && echo "same !" ``` ------- Funded by ESA for S2-MPC project

2020-02-07tests: add alternate checksums for libtiff 4.1Even Rouault
Fixes #1233 libtiff 4.1 slightly modifies the way it generates files. So add the new expected md5sum. Not super elegant solution admitedly.
2019-09-04openjp2/j2k: Validate all SGcod/SPcod/SPcoc parameter values.Sebastian Rasmussen
Previously the multiple component transformation SGcod(C) and wavelet transformation SPcod(H)/SPcoc(E) parameter values were never checked, allowing for out of range values. The lack of validation allowed the bit stream provided in issue #1158 through. After this commit an error message points to the marker segments' parameters as being out of range. input/nonregression/edf_c2_20.jp2 contains an SPcod(H) value of 17, but according to Table A-20 of the specification only values 0 and 1 are valid. input/nonregression/issue826.jp2 contains a SGcod(B) value of 2, but according to Table A-17 of the specification only values 0 and 1 are valid. input/nonregression/oss-fuzz2785.jp2 contains a SGcod(B) value of 32, but it is likewise limited to 0 or 1. These test cases have been updated to consistently fail to parse the headers since they contain out of bounds values. This fixes issue #1210.

2017-11-30opj_j2k_read_cod: remove check for 'No more than one COD marker per tile' ↵Even Rouault
(fixes #1043) This check was added per https://github.com/uclouvain/openjpeg/commit/daed8cc9195555e101ab708a501af2dfe6d5e001 to fix https://github.com/uclouvain/openjpeg/issues/476 , but it does not seem to be necessary with latest master (issue476.jp2 doesn't cause memory issues), and breaks reading legit files.
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.

2017-08-09Partial revert BPC related check of #975 (#979)Even Rouault
PR #975 introduced a check that rejects images that have different bit depth/sign per compoment in SIZ marker if the JP2 IHDR box has BPC != 255 This didn't work properly if decoding a .j2k file since the new bit added in opj_cp_t wasn't initialized to the right value. For clarity, tThis new bit has also been renamed to allow_different_bit_depth_sign But looking closer at the code, it seems we were already tolerant to inconsistencies. For example we parsed a JP2 BPCC box even if BPC != 255 (just a warning is emitted) So failing hard in opj_j2k_read_siz() wouldn't be very inconsistent, and that alone cannot protect against other issues, so just emit a warning if BPC != 255 and the SIZ marker contains different bit depth/sign per component. Note: we could also check that the content of JP2 BPCC box is consistant with the one of the SIZ marker.

2017-06-12Encoder: fix packet writing of empty sub-bands (#891, #892)Even Rouault
There are situations where, given a tile size, at a resolution level, there are sub-bands with x0==x1 or y0==y1, that consequently don't have any valid codeblocks, but the other sub-bands may be non-empty. Given that we recycle the memory from one tile to another one, those ghost codeblocks might be non-0 and thus candidate for packet inclusion.
