Fast, powerful 24-bit picture datatypes for AmigaOS® & MorphOS
68K (OS 3.x & Amithlon) and PowerPC (WarpOS, OS 4.x & MorphOS)
Copyright © 1999-2024 Oliver Roberts, All Rights Reserved.
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, PSD (Adobe Photoshop®) and WebP, 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.
| 11 January 2024 | WarpWebP V45.5 released |
| A new version of WarpWebP is now available, with the following changes:
- Updated with libwebp 1.3.2.
- Decoding of lossless images on 68k is now 30% faster.
- Various minor optimisations.
- Removed some redundant code.

| | 20 May 2023 | WarpDTPrefs V45.12 released |
| A new version of WarpDTPrefs is now available, with changes as follows:
- Fixed the default background checkboxes being disabled incorrectly due to the re-ordered alpha channel mode lists in the previous release.
- Increased minimum stack size to 16K, for safety.
- OS3 and MorphOS versions recompiled with VBCC 0.9h.
- OS4 version recompiled with GCC 11.2.0.

| | 8 May 2023 | WarpPNG V45.27 released |
| An updated version of WarpPNG is now available, with the following changes:

|
| | 30 October 2022 | WarpTIFF V45.12 released |
| An updated version of WarpTIFF is now available, based on the very latest
libtiff and with some other improvements:
- Updated with libtiff 4.4.0, zlib 1.2.12 and jpeglib 9e.
- Added support for reading tiled planar RGB/CMYK images.
- Faster decoding of LZW encoded images and some others.
- Disabled asynchronous i/o when loading images via OS4 vector-port filesystems, removing overhead to improve performance (still enabled for older filesystems such as FFS2 and SFS).
