When using the Image filter effect and pointing it to an SVG element, it seems like the source element is rendered at its normal size internally and then that render is stretched to the size of the destination element. When the destination element is much bigger, the source rendering is very pixelated. I would expect the source to be crisp at any size of the destination element, by rendering the source element using the destination size directly.
Inkscape version 0.47pre4, built Oct 17, 2009 on Windows XP w/ SP3.
Steps to reproduce:
1. Create a small object, like a star.
2. Create a much larger rectangle.
3. Open the Filter Editor (Filter > Filter Editor...).
4. Create a new filter and add the Image effect.
5. On canvas, select the star. In the Filter Editor, click the button "Selected SVG Element".
6. On canvas, select the rectangle. In the Filter Editor, check the box to apply the filter to the rectangle.
Now you can see how pixelated the star has become. It occurs even when exporting a PNG, which is supposed to always use the highest filter resolution. Image attached.
possibly the same issue: pixelated rendering in current 0.47(pre) and SVN versions of <svg:image … xlink:href=
