Short: Windows BMP datatype V44.3 (68k,WarpOS,MorphOS) Author: oliver@futaura.co.uk (Oliver Roberts) Uploader: oliver@futaura.co.uk (Oliver Roberts) Version: 44.3 Type: util/dtype Requires: OS 3.0+,picture.datatype v43+ Changes since previous release: - BMP descriptor no longer insists on BMP files having a .bmp extension - The dithering disabler feature (for when the OS3.5/3.9 picture.datatype is in use on hi/true colour displays) was flawed, since it only worked with images that were eventually attached to windows (e.g. Multiview). Now dithering will be disabled in all other cases too (e.g. Workbench / DOpus backdrops) FEATURES - Supports common BMP file types, including both Windows and OS/2 BMP formats. These include BMP images with a bit depth of 1, 4, 8, 16, 24 and 32, and also all RLE compressed BMP files - Highly optimized datatype dispatch engine and BMP decoder, resulting in a very efficient, compact and quick BMP 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 WarpBMP is a Windows BMP 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 WarpBMPdt.info 6876 4256 38.1% 19-Feb-01 11:49:36 +WarpBMP.datatype.020 144 128 11.1% 19-Feb-01 11:49:36 +WarpBMP.datatype.030.pch 768 614 20.0% 19-Feb-01 11:49:38 +WarpBMP.datatype.040.pch 1084 871 19.6% 19-Feb-01 11:49:38 +WarpBMP.datatype.060.pch 14772 6757 54.2% 19-Feb-01 11:47:18 +WarpBMP.datatype.elf 10060 5988 40.4% 19-Feb-01 11:46:38 +WarpBMP.datatype.wos 120 106 11.6% 19-Feb-01 11:55:14 +BMP 2519 1766 29.8% 15-Dec-99 14:24:28 +BMP.info 4996 1656 66.8% 17-Jan-01 15:41:36 +Install_WarpBMP 2025 1540 23.9% 17-Jan-01 15:42:44 +Install_WarpBMP.info 14636 9285 36.5% 16-May-96 12:42:42 +spatch 12964 5310 59.0% 19-Feb-01 11:56:42 +WarpBMP.guide 2924 2308 21.0% 15-Dec-99 16:37:44 +WarpBMP.guide.info -------- ------- ----- --------- -------- 76690 42435 44.6% 22-Feb-101 00:43:04 14 files
