I want to start with an example of a graphic I created way way back with Inkscape 0.38. Allow me to walk you through creating a filter in Inkscape 0.46. Unfortunately, you will need a fairly deep knowledge of 2D image processing to make use of SVG filters. But with the collection of other filters provided, it also provides a building block for constructing some very complicated and useful graphical operations that could previously only be done with a raster tool like The Gimp. On its own, Gaussian blur was an incredible useful filter, offering soft edges and powerful shading techniques. Inkscape's 0.45 release saw the implementation of its first filter: Gaussian blur. ![]() ![]() What this entails is that it's possibly to take very simple vector shapes, bung on a filter, and get some very pretty artwork which can still be edited as paths. SVG filters are a section of the SVG language for connecting simple, well-defined raster operations and applying those to rasterised vector shapes in the document. One of the most stunningly powerful features of the recently release Inkscape 0.46 is the ability to design SVG filters.
