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

To pass this test, the UA must render all 6 cases (SourceGraphic, SourceAlpha, BackgroundImage, BackgroundAlpha, FillPaint, StrokePaint) correctly. The result for in="SourceGraphic" is a non blurred vertical rectangle (green with dashed stroke) overlayed with three blurred circles (red/green/blue with dashed stroke). The result for in="SourceAlpha" is a non blurred vertical rectangle (green with dashed stroke) overlayed with three blurred circles (dark gray with dashed stroke). The result for in="BackgroundImage" is a blurred vertical rectangle (green with dashed stroke). The result for in="BackgroundAlpha" is blurred vertical rectangle (dark gray with dashed stroke). The results for in="FillPaint" and in="StrokePaint" are the same. They consists of a non blurred vertical rectangle (green with dashed stroke) overlayed with a blue rectangle with blurred edges. The size of the blue rectangles are bigger than the blurred circles.
