* LZW decoder: Squash scan-build error by adding assert.Michael Drake2017-04-051-0/+3
| | | | | | | Note, for scan-build to correctly interpret the assert, the library must be built in debug mode: $ scan-build-4.0 make VARIANT=debug

|
* fix buffer overrun due to LZW code clearingVincent Sanders2017-01-271-2/+14
| | | | | | The LZW code clearing function was not dealing with errors when obtaining the next code from the gif. this resulted in input buffer overruns and occasional segmentation faults.
* move lzw parameters to a structVincent Sanders2017-01-271-212/+234
| | | | | | Make all the lzw parameters members of a structure instead of being random globals. This allows for a future change to making the library safe when decompressing multiple GIF.
* when searching previous frames for disposal type stay in boundsVincent Sanders2017-01-251-6/+10
| | | | | | | | When searching back through frames looking for a non restore frame disposal type the array index would go out of bounds off the front of the frames block causing a segfault. Fixes issue #2515 reported in bugtracker

* -Wextra is only understood by GCC 3.4.6 or later. John Mark Bell2009-11-061-4/+5
| | | | | | | | | | | | | | | | It is a more descriptive synonym for -W. Use -W instead which is understood by all common versions of GCC (i.e. GCC 2.95 supports it, which is the oldest GCC version we have to support) Additionally, conditionalise our -Werror usage on whether we're building for BeOS/Haiku. On these platforms, the standard library headers result in warnings. GCC 2 is quite happy to build this code on other platforms, so shouldn't be the trigger for dropping -Werror (even if BeOS is the only target where GCC2 is likely to be used). svn path=/trunk/libnsgif/; revision=9667
* Fix palette entry population some more. Hopefully, it's completely endian ↵John Mark Bell2009-08-091-13/+33

* Stop utterly insane palette entry population.John Mark Bell2009-08-031-10/+15
| | | | | | | Palette entries are always ABGR, regardless of platform endianness. This change probably breaks big-endian platforms which, under the old approach, had palette entries of the form RGBA (assuming I understood the code correctly). svn path=/trunk/libnsgif/; revision=9027
