Branch: CURRENT, Version: 0.20, Package name: jbig2dec-0.20, Maintainer: pkgsrc-users

jbig2dec is a decoder for the JBIG2 image compression format. JBIG2 is
designed for lossy and lossless encoding of monochrome images at
moderately high resolutions. For scanned paper documents, compression
ratios on the order of 100:1 are often seen.

Version 0.20 (2023 August 28)

* Move definition of inline macro so that it doesn't cause
  linker errors during cross-compilation.

* Fix OSS-fuzz issue 10862, a memory leak, by freeing image
  resources upon error.

* Fix a bug where a buffer was accessed without considering
  alignment requirements on architectures such as SPARC.

* Fix compiler warnings.

* Improve custom memory allocator used in testing to restricting
  memory usage.

* Use silent automake rules when compiling as a separate project.

Changes:
0.19
----
 * API change to use full 32 bit segment numbers, in accordance
   to the JBIG2 specification.
 * Better handling of end of input data stream and and when
   encountering errors in the arithmetic decoder stream. This
   should improve many situations where jbig2dec appeared to
   run forever.
 * Fix several bugs related to signedness or over-/underflow
   checks that were not robust.
 * Bug fixes for issues reported by Coverity/OSS-fuzz.
 * Add option to limit memory usage to command line tool.
 * Update manpages, and command line tool usage.
