- Author: achimste@gmx.de (Achim Stegemann)
- Uploader: achimste@gmx.de (Achim Stegemann)
- Version: 40.3
- Type: docs/anno
-
- Requires minimum:
- * OS 3.0
- * WarpOS V4.
-
- ### This is the first datatype to decode GIF-images with WarpOS ! ###
-
- Note:
- * Only WarpOS !! No PowerUP module available and will never be from me.
-
- This datatype is completely freeware !! Use it as you like it.
- But when you use it, please send me an email for feedback.
-
- If you find any bugs, please report to the above email adress, including
- the picture, that failed to be decoded. If you don't include the picture, I might not be able to trace
- the bug !
-
- The archive contains full source code. The datatype was written with StormC V3 (PPC).
- The source code contains the FFR-module (asyncronous file I/O) by Matthias Scheler.
-
- Speed benchmarks on a PPC604e/200 and MC68060/50:
- Decoding time was about half the 68k time. As a reference I used the original OS 3.5 gif.datatype.
- Please keep in mind that this refers only to the decoding time ! Converting the picture to a
- different bitmap-format is performed by the picture.datatype, which is still 68k !
-
-
- Note:
- It is not allowed to upload any GIF-related programs to Aminet.

- History:
-
- V40.3:
- * Works now with OS 3.0 too.
- * Added missing error checking, when no bitmap could be allocated with V43.
- * Local colormap is no more skipped. That caused wrong color palette with some GIF anims.
- * Calculating the size of local colormap was wrong.
- This caused some images with a local colormap not to be displayed.
-
- V40.2:
- * Supports transparency color. IBrowse shows correct images.
- * Most GIF anims show the first frame.
- * Corrupt images caused a guru due to a stupid program fault.
- * Only global colormap is loaded. Local colormap is skipped.
- * Has problems with a few GIF anims to show first frame.
-
- V40.1:
- * Improved use of V43 features. Shouldn't allocate any ChipRAM an graphic cards.
-
- V40.0
- * First public release.
