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
