I can also confirm this bug.

Here is another test case:
http://www.carto.net/neumann/temp/imagescaling_test.svg

the same image is embedded three times and the width and height attributes always set such that it should scale the image unproportional. However, the image is always scaled proportional ;-(

Attachment: testcase - use preserveAspectRatio="none"

This behaviour is according to spec. The default value of the preserveAspectRatio attribute is 'xMidYMid meet', so if you don't want to preserve the aspect ratio you have to specify preserveAspectRatio="none". Here's your testcase with it added to demonstrate.

Thanks for the small testcase in the first place. They're always much appreciated, but unfortunately this bug is invalid.

-> INVALID

[Andreas Neumann]

I apologize for being misinformed. I read it in the spec and I think you and Mozilla/Batik are right and ASV/Opera are wrong.

Will have to forward the bug to them.

Thanks for clarification and all the best,
Andreas
