452473 webp: implement animation and metadata handling
This PR was initially meant to implement ICC reading, but as it turns out, following the official documentation just gives me three for the price of one
Thus, in this MR I've implemented, following the existing JPEG XL support (!1363 (merged)):
- metadata read/write
- animation handling
- ICC profile handling
- test suite (includes animation!)
There's a small price to pay, namely the import is no longer configurable, and so the corresponding dialog has been removed. I've only hardcoded use_threads
and mode
to ensure we keep using multithreading and the BGRA output mode we need for our RGBA8 color space.
This PR only adds a single string ("Save as animated WebP"), so it may be cherry-picked post 5.1 release.
Test Plan
Build Krita. Open the attached WebP images and ensure they display as expected.
In particular:
- Verify the loading_16.webp file shows a 32 FPS, 24-frame animation of a spinning wheel.
- Ensure the attachment in the bug report is loaded as WideRGB.
