This is a sample guide for all the Filter Effects available in Inkscape 0.47. A Filter Effect is an overlay on top of a vector object that visually modifies it to take on the qualities of a raster-based image. This allows for the rendering of complex shapes and textures that would normally be impossible/impractical to recreate using only vector paths, strokes and blurring effects. Since these are only overlays, Filter Effects can be enabled, disabled and modified by the user at any time.
Filter Effects have been around since 0.46, but the latest version integrates them better so that they are easy to access and use via the Filters menu option.
