Changes since previous Aminet release:

 - Updated with libpng 1.6.28 and zlib 1.2.11.
 - OS4 version recompiled with GCC 5.4.0.
 - Updated Spanish installer.


FEATURES

 - Supports both normal and interlaced PNG files

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

 - Alpha channel handling can be configured to output RGBA bitmaps, or
   RGB bitmaps either by combining the alpha information internally
   using a configurable background colour or simply stripping it

 - 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 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)

 - Based on libpng 1.6.28 and zlib 1.2.11


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+, P96 or CGraphX)

 68k version

 - 68020 processor or higher (optimized versions included)

 WarpOS version

 - PPC accelerator card + 68040/060
 - WarpUp Release 5.0 or higher

 OS4 version

 - PPC accelerator card / AmigaOne / SAM
 - AmigaOS 4.0 or higher

 MorphOS version

 - PPC accelerator card / Pegasos / Efika
