Changes since previous Aminet release:
- Updated with libwebp 1.3.2.
- Decoding of lossless images on 68k is now 30% faster.
- Various minor optimisations.
- Removed some redundant code.
FEATURES
- Handles both lossless WebP and lossy WebP images
- Different modes for handling alpha channels / transparency
- Highly optimized datatype dispatch engine and WebP decoder,
resulting in a very efficient, compact and quick WebP datatype
- Asynchronous file i/o and double buffering techniques (WarpOS only),
which speeds up image decoding
- Optimized versions for 68020, 030, 040 and 060
- PowerPC support with native OS4, WarpOS and MorphOS versions
- Alter the pen allocation precision when images are remapped to an
8-bit display
- Specific support for the AmigaOS picture.datatype v44+, when available
- The dithering feature of the AmigaOS picture.datatype v44+ can be
configured to your liking (e.g. disabled for 15/16-bit displays)
- Based on libwebp 1.3.2.
