opj_t1_encode_cblks: fix UBSAN signed integer overflow

2019-03-29T10:17:39Z

Fixes #1053 / CVE-2018-5727 Note: I don't consider this issue to be a security vulnerability, in practice. At least with gcc or clang compilers on x86_64 which generate the same assembly code with or without that fix.

Fix some potential overflow issues (#1161)

2018-10-31T19:44:30Z

* Fix some potential overflow issues Put sizeof to the beginning of the multiplication to enforce that size_t instead of smaller integer types is used for the calculation. This fixes warnings from LGTM: Multiplication result may overflow 'unsigned int' before it is converted to 'unsigned long'. It also allows removing some type casts.

opj_t1_decode_cblk(): move some code to codeblock processor for (theoretical) better multi-threading in subtile decoding

Tiny perf improvement in T1 stage for subtile decoding

Allow several repeated calls to opj_set_decode_area() and opj_decode() for single-tiled images

2017-09-01T14:30:48Z

* Only works for single-tiled images --> will error out cleanly, as currently in other cases * Save re-reading the codestream for the tile, and re-use code-blocks of the previous decoding pass. * Future improvements might involve improving opj_decompress, and the image writing logic, to use this strategy.
