Changing the width and height of the image element scales the drawing smooth. If I want to draw that image to a canvas, it will rasterize the SVG in its given dimensions (given in the SVG tag) and then scale the rasterized image to the desired dimensions which results an ugly drawing. IE9, Chrome10 and Safari5 all renders the SVG to the desired dimensions and puts it into the canvas resulting in a smooth image. Reproducible: Always Steps to Reproduce: 1. drawImage an image element with SVG src to the canvas with a scale other then 1:1 2. 3. Actual Results: The SVG is rasterized in its "natural" size (given in the SVG tag, not even related to the Image element containing it) and then scales to the dimensions given in drawImage. Expected Results: The SVG should be rasterized to the dimensions given in the drawImage parameters to ensure smooth scaling.

Corrected to refer to svg attachment

Presumably the issue is that we try to get an image surface out of the <svg> and the draw+scale that....

Precisely. See bug 603488.
