Short: JFIF-JPEG datatype (68k,WarpOS,MorphOS) V44.16 Author: oliver@futaura.co.uk (Oliver Roberts) Uploader: oliver@futaura.co.uk (Oliver Roberts) Version: 44.16 Type: util/dtype Requires: OS 3.0+,picture.datatype v43+ Changes since previous release: - Fixed a bug in the new startup code, which caused images not to be loaded in some cases - e.g. IPrefs failing to load WB backdrops - The 68020-040 versions were completely broken in the previous release - forgot to rebuild one of the link libraries - The 68k versions are faster again - moreorless back to the speed they were in 44.14 FEATURES - Supports regular JFIF files, and also many JPEG variant formats such as Exif, Adobe, Photoshop, Mavi, Windows, JCCK colorspace files and other less common formats - Supports both normal and progressive JPEG files - Highly optimized datatype dispatch engine, and fast JPEG decoder, resulting in a very efficient, compact and quick JPEG datatype - Asynchronous file i/o and double buffering techniques (WarpOS only), which speeds up image decoding - Optimized versions for 68020, 030, 040 and 060 - Native PowerPC support for both WarpOS and MorphOS - Specific support for the OS 3.5/3.9 picture.datatype, when available (dithering is also automatically disabled for hi/true colour screens) REQUIREMENTS WarpJPEG is a JFIF/JPEG datatype which utilizes and requires the following: - Kickstart 3.0 or higher - picture.datatype v43 or higher (i.e. either of the ones supplied with AmigaOS 3.5/3.9, P96 or CGraphX) 68k version - 68020 processor or higher (optimized versions included) WarpOS version - PPC accelerator card + 68040/060 - WarpUp Release 4 (powerpc.library V15) or higher MorphOS version - PPC accelerator card - MorphOS beta release 1 or higher Note that a graphics card is not necessary - the P96 or OS 3.5/3.9 picture.datatype will automatically dither images down to your display requirements. ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 2802 1850 33.9% 15-Dec-99 16:37:44 WarpJPEGdt.info 33436 19567 41.4% 12-Jan-01 18:59:52 +WarpJPEG.datatype.020 1168 956 18.1% 12-Jan-01 18:59:54 +WarpJPEG.datatype.030.pch 4280 3070 28.2% 12-Jan-01 18:59:56 +WarpJPEG.datatype.040.pch 2708 2182 19.4% 12-Jan-01 18:59:58 +WarpJPEG.datatype.060.pch 62336 26842 56.9% 12-Jan-01 18:57:52 +WarpJPEG.datatype.elf 54960 24966 54.5% 12-Jan-01 18:57:28 +WarpJPEG.datatype.wos 516 436 15.5% 02-Aug-00 17:31:42 +JPEG 2519 1766 29.8% 15-Dec-99 14:24:28 +JPEG.info 5960 1881 68.4% 11-Jan-01 15:22:12 +Install_WarpJPEG 2026 1542 23.8% 02-Sep-00 00:37:36 +Install_WarpJPEG.info 14636 9285 36.5% 16-May-96 12:42:42 +spatch 22079 8289 62.4% 12-Jan-01 20:12:00 +WarpJPEG.guide 2924 2308 21.0% 15-Dec-99 16:37:44 +WarpJPEG.guide.info -------- ------- ----- --------- -------- 212350 104940 50.5% 16-Jan-101 04:10:18 14 files
