Fast, powerful 24-bit picture datatypes for AmigaOS® & MorphOS
68K (OS 3.x & Amithlon) and PowerPC (WarpOS, OS 4.0 & MorphOS)
Copyright © 1999-2009 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 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.
5 December 2009 - WarpBMP V45.6, WarpJPEG V45.7 & WarpPNG V45.11 released
Unfortunately, the workaround for a bug in OS4's datatypes library was
not actually present in the previous updates of WarpBMP, WarpJPEG and WarpPNG,
despite the release notes saying otherwise. Updates which really do include
the workaround are now available, and additionally WarpPNG has been updated with libpng 1.2.41 (for all versions).

The WarpDT package (WarpJPEG, WarpPNG, WarpTIFF, WarpBMP, WarpPCX, WarpPSD and WarpDTPrefs)
is shareware, which means you are expected to register if you find
the datatypes useful after an evaluation period of 30 days, and wish to
continue using them.
|
· MysticView - great window based viewer to use with the WarpDTs, especially if you have graphics card.
· PicShow - another viewer, but this one also supports image files containing multiple images (e.g. TIFF-FAX).
· SplitMultiImage - extract images from image files containing multiple images.

| Attention WarpUp 5.1 users! |

Due to a bug in the official powerpc.library v16.1 (7 February 2001) from the OS3.9 boing bag,
you may experience crashes from Defiant (WarpOS housekeeping task). If this proves to be
the case on your system, I recommend that you try using the
16.1beta1 version (7 January 2001)
of powerpc.library instead, available from
Frank Wille's ppclibemu page. There is
no real need to bother trying this beta version unless you do get the Defiant crashes.
