Comment 1

[Emilio Cobos Álvarez (:emilio)]

So there are a lot of tests tracked by this bug, so I think work should be done in dependent bugs. There are a few tests here that seem interesting:

• html/canvas/element/drawing-images-to-the-canvas/2d.drawImage.incomplete.reload.html: This one interacts with image loading and thus doesn't seem super-easy.
• html/canvas/element/text-styles/2d.text.font.parse.complex.html seems like a bug in the test that expects a particular serialization, so the test should be patched instead of Firefox changed.
• html/canvas/element/pixel-manipulation/2d.imageData.create2.zero.html, this one seems trivial to fix, and is the first one I'd try.

Tests can be looked at in https://wpt.fyi/results/html/canvas/element/pixel-manipulation/2d.imageData.create2.zero.html, where there are links to run the test and so on. Interesting tests are the one that pass in at least one other browser and that we fail.

It seems like, for example, for the last one CanvasRenderingContext2D::CreateImageData should check for zero after clamping to int, rather than before.

Comment 2

[Aryan Agal]

I checked the tests on https://wpt.fyi
It seems that the following tests pass now:

1. /html/canvas/element/drawing-images-to-the-canvas/2d.drawImage.zerosource.html
2. /html/canvas/element/drawing-text-to-the-canvas/2d.text.measure.advances.html

Rest are all still failing, I'm starting work on them
