Abstract

Methods, systems, and apparatus, including computer program products for compactly encoding font information. In one aspect a method is provided that includes identifying a library of elements (630) where each element in the library of elements is associated with an outline (633) and one or more parameters (637). A glyph is identified that has one or more references (627) to a respective element in the library of elements (630). Each reference specifies a value for one or more of the parameters associated with the respective element. The glyph is rendered (680) based on each respective element referenced by the glyph. The value of the one or more parameters specified by each reference affects the appearance of the rendered element (645, 660, 670).
