After enabling WebP support in WebKit EFL port the canvas-toDataURL-webp.html test is failing. It looks like webp image format is not specified as supported image MIMEType for encoding. --- /home/lkrok/checkout/LocalWebKitOrg/WebKit/WebKitBuild/Debug/layout-test-results/fast/canvas/canvas-toDataURL-webp-expected.txt +++ /home/lkrok/checkout/LocalWebKitOrg/WebKit/WebKitBuild/Debug/layout-test-results/fast/canvas/canvas-toDataURL-webp-actual.txt @@ -1 +1,2 @@ +FAIL: canvas.toDataURL('image/webp') not supported

Chiming in to say that this would be very useful to have. Support was added to Gecko/Firefox in January 2022, meaning that WebKit is the only engine not implementing this now (see https://caniuse.com/?search=todataurl+webp). Cryptee Docs (https://crypt.ee/docs) uses this method for working with photos locally on the user's devices, and so is unable to support webp images on any browser because of WebKit's missing support for it.

+1. Webp is essential for transparent images with reasonable file size.
