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)
