Fast, powerful 24-bit picture datatypes for AmigaOS® & MorphOS
68K (OS 3.x & Amithlon) and PowerPC (WarpOS, OS 4.x & MorphOS)
Copyright © 1999-2020 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, 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.

24 May 2020WarpWebP V45.1 + WarpDTPrefs V45.11 released
A brand new datatype for reading WebP images is now available, along with an accompanying WarpDTPrefs update. This is provided free of charge to existing registered users, but partly as a result of this new addition, pricing for new users has been amended and also direct payment in CAD and AUD is now possible, in addition to GBP, EUR and USD.

Changes for WarpDTPrefs are as follows:

  • Re-ordered options in alpha channel mode lists.
  • Added new settings for WarpWebP.
12 May 2020WarpJPEG V45.15 released
An updated version of WarpJPEG is now available, mainly containing WarpDT engine improvements and bug fixes:
  • Completely reworked more intelligent detection of features available in differing picture.datatype versions.
  • Fixed decoding of greyscale images on MorphOS.
  • Removed some redundant code and reduced memory usage.
  • 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.
12 May 2020WarpTIFF V45.11 released
An updated version of WarpTIFF is now available, mainly containing WarpDT engine improvements and a minor speed boost:
  • Increased speed of deflate decoding (5% faster).
  • Removed some redundant code.
  • Tweaked prefs loading routine change from previous version to restore performance when not using MorphOS, to match the latest WarpDT engine changes.
11 May 2020WarpPNG V45.23 released
A newly updated, faster version of WarpPNG is now available, with the following changes:
  • Relaxed integrity checks to increase performance. Now 15-20% faster on 68k, 5-10% faster on OS4, 7% faster on WarpOS and 5% faster on MorphOS.
  • Allow images with incorrect CMF bytes to be loaded - such images should really be fixed with pngfix [BUGID 0002].
  • Fixed faulty parsing of the background colour option.
  • Fixed incorrect default background colour reading on WarpOS.
  • Completely reworked more intelligent detection of features available in differing picture.datatype versions and a more robust detection of alpha channel support (OS 3.1.4 no longer misidentified as alpha aware).
  • 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.
9 May 2020WarpBMP V45.8, WarpPCX V45.6 & WarpPSD V45.6 released
New versions of WarpBMP, WarpPCX and WarpPSD are now available, incorporating changes in the WarpDT engine:
  • 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.
5 May 2020WarpDTPrefs V45.10 released
A new version of WarpDTPrefs is now available which no longer requires resource.library from OS3.5/3.9. Full list of changes:
  • Added alpha channel options for WarpTIFF 45.10.
  • Enabled tab cycling.
  • Fixed corruption at end of saved BMP, PCX and PSD prefs files.
  • GUI code completely reworked (no longer requires the ReActor GUI builder's resource.library from OS3.5/3.9).
  • Added OS4 and MorphOS PowerPC native versions.
  • Integrated new picture.datatype feature detection code from the WarpDT engine.
3 May 2020WarpTIFF V45.10 released
A heavily updated version of WarpTIFF is available (the fixes to the WarpDT engine will be making their way to WarpJPEG and WarpPNG in the next few days) with changes as follows:
  • Updated with libtiff 4.1.0, zlib 1.2.11 and jpeglib 9d.
  • Fixed bug in file i/o optimizer, which could cause images with errors in their TIFF directory to fail to load properly.
  • Added support for 32-bit and 64-bit floating point samples.
  • Added pure 32-bit RGBA output for images accompanied by an alpha channel (requires a picture.datatype supporting RGBA - e.g. OS4, MorphOS and AfA OS).
  • Added ALPHA_MODE option to control whether the alpha channel is passed through to picture.datatype, discarded or combined with a background colour.
  • Added user control of the background colour to use when combining with an alpha channel.
  • Completely reworked more intelligent detection of features available in differing picture.datatype versions and a more robust detection of alpha channel support (OS 3.1.4 no longer misidentified as alpha aware).
  • Changed prefs loading routine due to broken dos/ReadArgs() in MorphOS 3.x (RDAF_NOALLOC and RDA_Buffer completely ignored!), which was causing the prefs to not always be read properly.
  • Minor optimizations and cleanups.
  • MorphOS and WarpOS versions recompiled with VBCC 0.9g.
  • OS4 version and MorphOS AltiVec code 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.
21 April 2020WarpJPEG V45.14 released
An updated version of WarpJPEG is available with changes as follows:
  • Further 10% speed increase when using AltiVec (OS4 and MorphOS).
  • 5-10% faster on 68k and MorphOS, and 2% faster on WarpOS.
  • Merged in changes from IJG jpeglib v9d.
  • Minor optimizations and improvements.
  • MorphOS and WarpOS versions recompiled with VBCC 0.9g.
  • OS4 version and MorphOS AltiVec code 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.
