Fork of openjpeg library for JPEG2000 encoding and decoding https://git.carlh.net/cgit/openjpeg/atom?h=v2.2.0 2017-08-09T09:34:08Z 2017-08-09T09:34:08Z Even Rouault even.rouault@spatialys.com 2017-08-09T09:34:08Z urn:sha1:ac375ac9f5b4ae47501b60795e905e3d25dd00f8 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. 2017-07-27T16:10:03Z Even Rouault even.rouault@spatialys.com 2017-07-26T21:25:38Z urn:sha1:d6fa30099797c68c6a67decf58571dd59dbf734b Fixes warning found on clusterfuzz-testcase-minimized-5146316340461568 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=2495 Credit to OSS Fuzz 2017-06-12T16:37:50Z Even Rouault even.rouault@spatialys.com 2017-06-12T10:23:55Z urn:sha1:73d1510d473b7dcfccfdee57e0e511e6791d5091 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. 2017-06-09T08:49:03Z Even Rouault even.rouault@spatialys.com 2017-06-09T08:47:13Z urn:sha1:81c5311758a0ae1f1aea349a6ee0bca2a238fa79 There were a number of defects regarding when and how the termination of passes had to done and the computation of their rate. 2017-05-23T12:31:39Z Even Rouault even.rouault@spatialys.com 2017-05-23T11:46:04Z urn:sha1:2d2c368b19ee59cba7470c94bcc2c06ca6db1d80 2016-09-21T22:30:34Z Matthieu Darbois mayeut@users.noreply.github.com 2016-09-21T22:30:34Z urn:sha1:fac916f72a162483a4d6d804fd070fdf32f402ed Malformed PNM file could cause a crash in opj_compress.
