requester is opened (bug fixed in intuition.library 53.32).

4 July 2003 - V45 Warp Datatypes released
After a long delay, the promised updates to all the warp datatypes are

· BMP/JPEG/PNG/TIFF: Bumped version to v45 since a stable release has now been reached
and to reflect the jump to shareware status

· 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)

error. Now the part of the image that was successfully decoded is returned.

· 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

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.
