(Looks like this spec text still makes a binary distinction between "scaling up" vs "scaling down", which doesn't actually cover the space of possibilities, as Simon says above.) Could this be clarified in the spec? For reference, it looks like Blink's implementation does what Simon suggested -- it pixelates when *at least one* dimension is being scaled up: http://src.chromium.org/viewvc/blink/trunk/Source/core/rendering/ImageQualityController.cpp?r1=176839&r2=176957&pathrev=176957 http://src.chromium.org/viewvc/blink/trunk/Source/core/rendering/RenderHTMLCanvas.cpp?r1=176839&r2=176957&pathrev=176957 ~Daniel
