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.
