Summary Need to implement SVG Filter "smart effect boundaries"
W. James MacLean
Reported 2010-06-25 13:12:29 PDT
When rendering an image like http://en.wikipedia.org/wiki/File_talk:Unix_history-simple.svg , which contains a filter that specifies filterUnits="userSpaceOnUse", the image's SVG filters are applied to the entire canvas for each object, instead of just the minimum necessary region around each affected object. This leads to unnecessarily long rendering times (this image can take several minutes as the filter is applied multiple times to the entire canvas). The code should be modified to calculate the minimum effected region around each object, and just apply the filter to that instead.
