Thereafter, the file is split into segments of the following forms, Just about every launched by a 1-byte sentinel:
When processing an uncompressed GIF, a standard GIF decoder will not be prevented from crafting strings to its dictionary table, although the code width should by no means enhance since that triggers a distinct packing of bits to bytes.
