gif decoder is failing in GIF2.cpp, line 365 /* Check for a code not defined in the dictionary yet. */ if (code > avail) return -1; code is 0x500 and avail is 0x452
Created attachment 130364 [details] [diff] [review] tweak lzw decoder Looking through a number of other gif decoder implementations (gimp, gtk+, ImageMagick), we seem to be interpreting a code that isn't in the dictionary differently. We were treating it as an error, while others use it as the firstcar condition. (Hunk 1) Patch also removes some redundant code2 logic and changes the loop condition of the while loop to match other decoders. (Hunk 2&3)
