Public bug reported: I was trying to create an image sprite by embedding a base64 encoded PNG image into an SVG file. I then applied a greyscale filter over that image. When I view the SVG in a browser the contents render correctly. When I use rsvg-convert to create a PNG image the filter is not applied, or in another test case, the filter gets renderd as a block box.
In the sample file below I have created two cases. Case 1: A greyscale filter is applied to an image element. Case 2: A filter containing both an feImage and feColorMatrix is applied to a rectangle. Using rsvg-convert, in Case 1 the filter is not applied to the output. In Case 2 the output is rendered as a black box. rsvg-convert version 2.36.1 from : http://code.google.com/p/osspack32/ Windows 7 64-bit Also as a test, when I try to load my test file in Inkscape it causes it to crash. However, when I remove my filter for Case 2, Inkscape will now load the file and render it correctly. But, like with rsvg-convert, when I try to save the file as a PNG, it fails to apply the filter. <?xml version="1.0" encoding="UTF-8"?> <svg xmlns:xlink="http://www.w3.org/1999/xlink";
