Author:   oliver@futaura.co.uk (Oliver Roberts)
Uploader: oliver@futaura.co.uk (Oliver Roberts)
Version:  44.17
Type:     util/dtype
Requires: OS 3.0+,picture.datatype v43

Changes since previous release:

 - Updated with libpng 1.0.11 (this should have been in yesterday's
   update - blame my ISP's webcache :).


FEATURES

 - Supports both normal and interlaced PNG files

 - Gamma correction options allow the output image to be changed to
   suit your monitor/environment

 - Highly optimized datatype dispatch engine, and fast PNG decoder,
   resulting in a very efficient, compact and quick PNG 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 WarpOS and native MorphOS versions

 - Alter the pen allocation precision when images are remapped to an
   8-bit display

 - 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)

 - Based on libpng 1.0.11 and zlib 1.1.3


REQUIREMENTS

WarpPNG is a PNG 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.
