fs36 Category Description
fs16 pard s0 li2116 fi0 ri1007 ql tx2494 tx2872 tx3250 f1 b0 fs28 fs16 fs28 Implements the custom GIF decoding engine. Upon entry into b -_decodeFromStream:b0 , the decoder progressively decodes each part of the image stream by calling the various decoding methods implemented by this category.
fs16
fs28 fs16 fs28 The b UnsupportedBlocksb0 category defines stub methods that simply skip unsupported GIF blocks without producing an error message.
fs16
fs28 fs16 fs28 The code is heavily documented.
