Various approaches are disclosed for generating an output graphical object from an input graphical object. In one approach, vector graphics data representing the input graphical object in a memory are stored. A first subset of the vector graphics components of the vectors graphics data to leave unchanged for the output graphical object, a second subset of vector graphics components to alter for the output object, and a third subset of vector graphics components to discard from the output object are determined. Each vector graphics component in the second subset is altered, and the first and altered second subsets of vector graphics components as the output graphical object.
