animate-elem-87-t

93.6% of the ink matches
fail - measured over 56304 pixels carrying ink in either image.
These results are not meaningful. This check renders a single static frame, and nothing in a test document records which moment in time its reference image was captured at - so a correct SMIL implementation and a broken one are equally likely to mismatch. Animation behaviour is covered by dedicated unit tests instead; see ctgnz/foxglove#208 for a real measurement methodology, still to be worked out.

Difference

Difference
In the difference panel, red marks pixels that differ beyond tolerance and grey marks matching content. The tinted band, where present, is the <text id="revision"> legend every test carries: it renders in a fallback font this library cannot match, so it is excluded from the comparison entirely rather than failing every test.

What this test checks

The test is passed if the blue circle on the right is always the same size as the orange circle on the left. The test runs from t=0s until t=4s.
