9 December 2005 - Server change
The change went pretty smoothly, so hopefully nobody noticed that this website changed to a different hosting provider today.
What should be noticable though is that downloads are much faster on our new server. Other than that, business as usual - an update to WarpJPEG will be coming soon, and I am also working on an updated WarpTIFF.
Happy Christmas to everybody, and especially to those of you who have chosen
to buy the WarpDTs!

- Tweaked installer so that it checks for picture.datatype in MOSSYS:
as well as SYS: when run under MorphOS.
|
5 July 2003 - Errornous timeouts bugfix
Unfortunately, due to last minute changes, I broke the timeout code
slightly - doh! This resulted in the datatypes producing timeout warnings
unnecessarily. Fixed versions of all 5 datatypes now available.
Apologies for any confusion caused.
|
4 July 2003 - V45 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.

4 July 2003 - WarpDT.co.uk website launched
New website to accompany the transition of datatypes from V44 to V45.
|
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.
