Short:        ZSoft PCX datatype V45.6
Author:       oliver@futaura.co.uk (Oliver Roberts)
Uploader:     oliver futaura co uk (Oliver Roberts)
Type:         util/dtype
Version:      45.6
Requires:     OS 3.0+,picture.datatype v43+
Architecture: m68k-amigaos; ppc-amigaos; ppc-morphos; ppc-warpup


Changes since previous Aminet release:

 - Applications may now configure the datatype settings via a local
   variable, overriding any global user settings present in ENV:.
 - Completely reworked more intelligent detection of features
   available in differing picture.datatype versions.
 - Changed prefs loading routine due to dos/ReadArgs() on MorphOS not
   being fully compatible with AmigaOS, which was causing the prefs
   to not always be read properly.
 - Replaced usage of old Exec and Dos OS4 functions with the new ones.
 - Minor optimizations and improvements.
 - MorphOS and WarpOS versions recompiled with VBCC 0.9g.
 - OS4 version recompiled with GCC 8.1.0.
 - All benchmarks recomputed after the repair of my A1200, with
   SCSI2SD replacing my SCSI HDD and disabling all debug tools.
 - Updated Spanish installer.


FEATURES

 - Read standard ZSoft PC Paintbrush PCX files, including less common
   non-standard modes which Cloanto Personal Paint can save

 - Supports pixel bit depth of 1 or 8 and 1-8 planes of data, covering
   mono 1-bit images upto 24-bit RGB, both RLE compressed and uncompressed

 - Highly optimized datatype dispatch engine and PCX decoder,
   resulting in a very efficient, compact and quick PCX datatype

 - Asynchronous double buffering techniques (WarpOS only) and file i/o,
   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)
