Author: oliver@futaura.co.uk (Oliver Roberts)
Uploader: oliver futaura co uk (Oliver Roberts)
Type: util/dtype
Version: 45.7
Requires: OS 3.0+,picture.datatype v43+
Architecture: m68k-amigaos; ppc-amigaos; ppc-warpup; ppc-morphos
Changes since previous Aminet release:
- When the OS3.2 V47 picture.datatype is in use, decoding speed will
now be 10-30% faster for RGB, palette based and bitmap images on
both 68k and WarpOS.
- When the OS4 V54 picture.datatype is in use, decoding speed will
now be 5-40% faster for RGB, palette based and bitmap images.
- Significantly reduced memory usage when decoding 24-bit RGB images,
if using the OS3.2 V47 or OS4 V54 picture.datatype.
- Fixed crash on OS3 when using picture.datatype V44+.
- Tweaked version string so that CPU information can be viewed with
the version command.
FEATURES
- Handles Adobe Photoshop® 2.5, 3.0, 4.0, 5.0 and 6.0 images
(currently does not support layered images)
- Most of the available modes are supported, including 24-bit RGB,
Greyscale, Monochrome, 256 colour palette-based and CMYK images.
Images using RLE compression are also supported
- Highly optimized datatype dispatch engine and PSD decoder,
resulting in a very efficient, compact and quick PSD datatype
- Asynchronous file i/o and double buffering techniques (WarpOS only),
which speeds up image decoding
- Optimized versions for 68020, 030, 040 and 060
- PowerPC support with native OS4, WarpOS and MorphOS versions
- Alter the pen allocation precision when images are remapped to an
8-bit display
- Specific support for the AmigaOS picture.datatype v44+, when available
- The dithering feature of the AmigaOS picture.datatype v44+ can be
configured to your liking (e.g. disabled for 15/16-bit displays)
