the problem described here -> https://bugs.freedesktop.org/show_bug.cgi?id=64125 is caused by a missing width and height attribute of the SVG given as an example. So, what would we expect given a ViewBox attribute when importing a graphic? What I'd expect is that the aspect ratio is kept and a reasonable scaling is applied in order to fill a page, table cell or whatever. And that the little green squares (handles?) behave like a bounding box for the graphic content. Is that correct?
Hi Christina, hmm - since there is no viewport given, I'd assume svg takes the whole surrounding space, i.e. the draw page in this case. The ViewBox would then be relative to that user coordinate system, scaling the content to fill it. Since there is no preserveAspectRatio given, I read the spec that then the default of xMidYMid is taken, so indeed scaling should be uniformely. Does that match your reading? That would be using: - http://www.w3.org/TR/SVG/coords.html#ViewportSpace - http://www.w3.org/TR/SVG/coords.html#EstablishingANewViewport - http://www.w3.org/TR/SVG/coords.html#ViewBoxAttribute - http://www.w3.org/TR/SVG/coords.html#PreserveAspectRatioAttribute
What I've achieved so far is the correct scaling. What I'm looking for is where the total size of the graphic is still determined wrong (see attached screenshot) -> little green squares are more like DIN A4 than the ViewBox size.
Can you submit the patch (gerrit preferred, you can give yourself a -1 review to prevent Fridrich from merging it straight away ;)), would need to look into that a bit. :) Cheers, -- Thorsten
