Short: Windows BMP datatype V44.4 (68k,WarpOS,MorphOS)
Author: oliver@futaura.co.uk (Oliver Roberts)
Uploader: oliver@futaura.co.uk (Oliver Roberts)
Version: 44.4
Type: util/dtype
Requires: OS 3.0+,picture.datatype v43+
Changes since previous release:
- Added preferences options to configure the OS3.5/3.9 dithering control
feature.
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
- The dithering feature of the OS 3.5/3.9 picture.datatype can be
configured to your liking (e.g. disabled for 15/16-bit displays)
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.
