Fast, powerful 24-bit picture datatypes for AmigaOS®
68K (OS 3.x & Amithlon) and PowerPC (WarpOS, OS 4.0 & MorphOS)
Copyright © 1999-2015 Oliver Roberts, All Rights Reserved.

WarpDT The WarpDT package comprises of a collection of picture datatypes, and an accompanying easy-to-use preferences program. The image formats currently supported are JFIF/JPEG, PNG, TIFF, Windows BMP, PCX and PSD (Adobe Photoshop®), although support for more formats is planned. One of the key features of the datatypes is their superior decoding speed (hence the name Warp), especially on PowerPC equipped systems, and most importantly not at the expense of power and features. The datatypes have very efficient memory usage, which in particular helps 68K systems, whilst on PowerPC, AltiVec acceleration is offered on AmigaOS 4.x and MorphOS, and WarpOS users get the full benefit of combined 68K/PowerPC dual-cpu performance.

25 August 2003WarpPCX V45.1 released
Today, a new addition to the WarpDT family was born (and free to existing registered WarpDT users). As the name suggests, WarpPCX can read ZSoft PC Paintbrush files (PCX). A new version of WarpDTPrefs is also available, providing support for WarpPCX.

The WarpJPEG archive has been updated with the correct version of the datatype for WarpOS (contained V45.1 before).

9 July 2003V45.3 bugfix update

4 July 2003V45 Warp Datatypes released
After a long delay, the promised updates to all the warp datatypes are finally here. Summary of changes:

· BMP/JPEG/PNG/TIFF: Minor optimizations and cleanups.
· BMP/JPEG/PNG/TIFF: Bumped version to v45 since a stable release has now been reached and to reflect the jump to shareware status
· BMP: Fixed problems with decoding bitfield images
· JPEG: Altered descriptor file to prevent it matching LhA or LZX archives containing JPEG files (or anything else that might contain a JFIF header, other than Photoshop files)
· PNG: PNG files not containing enough data are no longer treated as a fatal error. Now the part of the image that was successfully decoded is returned.
· PNG: Updated with libpng 1.2.5
· PNG/TIFF: Updated with zlib 1.1.4
· TIFF: Now correctly converts images using the YCbCr colourspace to RGB
· TIFF: Added support for JPEG decompression
· TIFF: Updated to libtiff 3.6.0-beta2, including a new version of the LogLuv decoder, and numerous other bugfixes
· Prefs: Various parts of code rewritten, in preparation for losing the currrent reliance on resource.library
· Prefs: Minor bugfixes
· Prefs: Correct Polish and Portuguese documentation now included.
