No layer support? Or can that be faked by using 4 channel-chunks?
Probably easier to fake with frames of animation, but JXL is not a replacement for .PSD or .XCF files and I do not know what usecase layers would be for besides authoring
In my company’s product, we allow users to place images into a composition and alter the colors (like tinting/colorize in Photoshop, so only globally). When doing that, the outline of the drawn image should not change color, and also there might be multiple color areas (think an image of a house where the walls have a separate color from the chimneys).
To do separate full-image manipulation, we need multiple layers. Right now they’re just a tilemap with the layers next to each other, but that doesn’t work for repeating patterns.
