Abstract
A method of rendering a glyph of a vector-based font comprises the steps of: generating a MIP map for a glyph, where the MIP map comprises at least one level having a plurality of pixels and where each level is generated from original vector data for the glyph; and storing the MIP map on a computer readable medium. The method further comprises placing the glyph in an image to be rendered; retrieving the stored MIP map for the glyph; rendering a level of the MIP map, where the level is associated with a resolution of the glyph; and displaying the glyph as the rendered level.
