This is a stripped version of the Independant JPEG Group's library, available at <http://www.ijg.org/>. The following features have been removed to decrease source code size: * All encoding code. * All sample applications. * Most documentation. * Unix configure scripts. * Multiple Makefiles. * Multiple memory managers. * Disk-based backing store. If you don't have enough memory to decode a JPEG file, you probably can't play ZDoom either. * Fast integer DCT routines. * Floating point DCT routines. * Arithmetic coding, due to its patented status. (It is not normally built in the standard version of the library, either.) * Far pointers. Who cares about 16-bit x86? Not me. * IDCT scaling. * Block smoothing. * Color quantization. Looking it up in the RGB32k table is good enough for me. * Transcoding routines. * Buffered image output. * Raw data output. A Unix build of ZDoom should just use the system libjpeg instead of this code.
