Datatype: WarpJPEG 45.12 and WarpDTPrefs 45.7
Oliver Roberts has updated his Warp-datatype for JPEG-graphics as well as the corresponding preferences programm WarpDTPrefs. Under AmigaOS 4 and MorphOS it now offers Altivec support which makes the JPEG-decoding at least one and a half times faster compared with version 45.11.
If under MorphOS there is also a higher decoding speed compared with the original datatype of the operating system is not known yet. The original datatype also supports Altivec.
Changes:
- Added AltiVec speed optimizations for the OS4 and MorphOS versions making decoding speed of baseline images 1.5x faster on a G4 and 1.9x faster on a PA6T, with fancy upsampling off, on average. With fancy upsampling on, the AltiVec speed gain is even greater - 1.9x faster on a G4 and 2.3x faster on a PA6T. These optimizations can be toggled off/on using the new USE_ALTIVEC setting
- Huffman decoder in PowerPC versions is now 5-10% faster
- Reintegrated higher quality fancy upsampling smoothing feature from IJG jpeglib v6b which had not been present since WarpJPEG 45.5 due to its removal from IJG jpeglib v7 and higher
- MorphOS and WarpOS versions recompiled with VBCC 0.9d
- Added new set of benchmarks for OS4 (benchmark updates for other platforms suspended until my A1200 motherboard has been repaired)
