| Short: JFIF (JPEG) picture datatype 44.11 Author: gni at gecko.de (Gunther Nikl), Henryk Richter Uploader: henryk richter gmx net (Henryk Richter) Type: util/dtype Version: 44.11 Architecture: m68k-amigaos >= 3.0.0 Distribution: NoCD Date: 2019-12-27 Download: EXTERNAL LINK - Readme: EXTERNAL LINK This release of JFIFdt incorporates improvements to the datatype dispatch code alongside with an updated JPEG library. Assembly level optimization has been done in order to improve runtime performance considerably. Due to the optimizations, this is the fastest JPEG datatype for 68k Amigas. The datatype is an all-in-one binary for any 68020+ Amiga. A 68000 version (without assembly optimizations) is provided as well. Changes in this release - with some JPEGs, color clipping was wrong (in one of the color conversion cases), fixed. Vamp related feats - AMMX optimization for Apollo Core Gold 2.7 and later - FPU and AMMX availability is checked before use at runtime Other m68k and AOS Feature overview - supports normal and progressive JFIFs with all its flavours - supports HAM output (HAM6 as well as HAM8) - switches to V43 mode if a picture.datatype V43 or newer is found - asynchronous file I/O to speedup image loading and decoding - utilizes WritePixelLine8() for chunky-to-planar in V42 mode - automatic colour quantizing of true-colour data for V42 - can be configured to suit personal preferences - OS 3.5+ support (minimum OS3.0) - FBlit support - based on libjpeg-turbo - ASM optimizations to Huffman decoding, iDCT and color transform (68020+) - support for XMP JFIF files - all-in-one binary for 68020+
