Andreas Kleinert. All rights reserved. Needs Kickstart V3.1 (NOT 3.0) & SetPatch 43.x & Pic-Dt 43.x Program information ------------------- akPNG.datatype is a PNG datatype, which is based on the latest stable PNG sources (zlib V1.2.3, libpng version 1.2.31). It does support 8 Bit color mapped files (colorspace expanded to 8 bit per component always) and True color files (24/48 Bit, alpha channel supported in V43 mode, 48 Bit 16:16:16 cut down to 24 Bit 8:8:8). [ More detailed description can be found in akPNG.guide ] WARNING: if the pic-dt of your OS version does not support alpha channel handling, then always set STRIPALPHA=ON (no ARGB/RGBA) -------------------------------------------------------------------------- You should use the included preferences program for best configuration.
