Abstract
Methods for rendering font objects include: receiving input identifying an object to be rendered; selecting a data set for rendering the object from: (a) a first data set including font object data in a first format (e.g., trajectory data), and (b) a second data set including font object data in a second format (e.g., outline data); and rendering the object using the selected data set. The data set may be selected based on at least one run time parameter, such as the ppem or space available for the rendering, the desired text size, system resolution, font object complexity, contextual information, etc., to provide a high quality rendered image. Additional data sets (e.g., augmenting data, enhancing data, etc.) may be included to provide more rendering options to further increase the quality of the rendered image under some conditions. The various data sets may be independently created so that each data set can be produced specifically targeted to selected rendering conditions (such as a selected ppem range).
