- New feather: support gif animation input/output. It is not perfect, but he is practical.
- Processing can only be done in GIF animation mode when one GIF is opened; otherwise, only one frame can be processed.
- Only one frame can be previewed.
- The result will be saved directly to album.
- Magick (including the quick menu in the top right corner) does not support GIF processing.
- Update ncnn/magick/opencv/libwebp
