Fast, powerful 24-bit picture datatypes for AmigaOS® & MorphOS
68K (OS 3.x & Amithlon) and PowerPC (WarpOS, OS 4.x & MorphOS)
Copyright © 1999-2022 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.
| 27 October 2021 | WarpPSD V45.7 released |
| WarpPSD has been updated, with a crash bug-fix for OS3 and speed
boost for AmigaOS 3.2 users:
- When the OS3.2 V47 picture.datatype is in use, decoding speed will
now be 10-30% faster for RGB, palette based and bitmap images on
both 68k and WarpOS.
- When the OS4 V54 picture.datatype is in use, decoding speed will
now be 5-40% faster for RGB, palette based and bitmap images.
- Significantly reduced memory usage when decoding 24-bit RGB images,
if using the OS3.2 V47 or OS4 V54 picture.datatype.
- Fixed crash on OS3 when using picture.datatype V44+.
- Tweaked version string so that CPU information can be viewed with
the version command.

| | 17 October 2021 | WarpJPEG V45.16 and WarpPNG V45.24 released |
| New versions of WarpJPEG and WarpPNG are now available, mainly directed at users
of AmigaOS 3.2, where a speed boost has been unlocked. If you're still using the
CyberGraphX picture.datatype V43, and don't need the newer features, stick
with it as it is still faster than the picture.datatype V47 from AmigaOS 3.2.
Changes for WarpJPEG are as follows:
- Further optimized data cache utilisation on OS4 and MorphOS to
allow up to 5% faster decoding performance (10% with AltiVec).
- When the OS3.2 V47 picture.datatype is in use, decoding speed will
now be 5-10% faster for both 68k and WarpOS.
Changes for WarpPNG are as follows:
- When the OS3.2 V47 picture.datatype is in use, decoding speed will
now be 5-10% faster for both 68k and WarpOS.
- When the OS4 V54 picture.datatype is in use, decoding speed will
now be 5-10% faster and up to 25% faster for interlaced images.
- Significantly reduced memory usage when decoding interlaced
images, if using the OS3.2 V47 or OS4 V54 picture.datatype.

| | 30 August 2021 | PicDTBench V1.1 released |
| | I've released a new tool called PicDTBench, which allows you to benchmark the time it takes to load any image via picture.datatype. |
| | 8 June 2021 | Streamlined payment process + 11 new currencies supported |
| | The registration process has been simplified and cleaned up a little and I have switched my payment partner from PayPal to Stripe. Debit and credit cards are
still accepted as before, whilst it is now also possible to pay via Google Pay or Apple Pay. Payments can also be made with online banking in Germany (giropay),
Belgium (Bancontact), Austria (eps), Netherlands (iDEAL) and Poland (Przelewy24).
In addition to the already offered prices in Australian Dollars, British Pounds, Canadian Dollars, Euros and United States Dollars, it is now possible to pay in
Czech Koruna, Danish Krone, Hungarian Forint, Japanese Yen, New Zealand Dollar, Mexican Peso, Norwegian Krone, Polish Zloty, Russian Ruble, Swedish Krona and Swiss Franc.
The aim being to avoid currency conversion fees associated with payments, which PayPal will have charged before (hidden in their exchange rate) in these countries previously,
when converting from local currency to Euros, which should in turn mean cheaper prices. If your currency is still missing, or you are having problems with the store
showing the incorrect currency, please let me know and I'll look into it. |
| | 16 March 2021 | WarpWebP V45.2 released |
| An updated version of WarpWebP is now available, with changes as follows:
- Updated with libwebp 1.2.0.
- BUGID 0003: Fixed images not being displayed with some picture.datatype versions.
- Minor optimisations.
|
| | 24 May 2020 | WarpWebP 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 2020 | WarpJPEG 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 2020 | WarpTIFF 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 2020 | WarpPNG 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.
