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).

Claims18

Dependent claims

A method for rendering a desired font object, comprising:

receiving input data representing the desired font object to be rendered, wherein the input data includes information indicating that the desired font object includes at least a first portion and a second portion, information indicating nominal positions of the first and second portions in the desired font object, and information indicating nominal sizes of the first and second portions in the desired font object;
obtaining, based at least on the input data, a first data set for rendering the first portion of the desired font object, wherein the first data set includes data relating to a first guiding frame associated with at least the first portion of the desired font object;
obtaining, based at least on the input data, a second data set for rendering the second portion of the desired font object, wherein the second data set includes data relating to a second guiding frame associated with the second portion of the desired font object;
and
rendering the desired font object using at least the input data, the first data set, and the second data set, wherein the input data including information indicating the nominal positions and nominal sizes of the first and second portions of the desired font object define nominal relative positioning and nominal relative sizing of the first and second guiding frames, and wherein the first data set is used in determining at least one of a displayed relative position or displayed relative size of the first and second guiding frames during the rendering, the displayed position and/or size of the second portion in the rendered font object being based at least on the position and/or size of the second guiding frame, the displayed position being different than the nominal position of the second portion and/or the displayed size being different than the nominal size of the second portion.

receiving a first data set for rendering the first portion of the desired font object, wherein the first data set includes data relating to a first guiding frame associated with the first portion of the desired font object the first data set comprising first modification information related to the first guiding frame;
receiving a second data set for rendering the second portion of the desired font object, wherein the second data set includes data relating to a second guiding frame associated with the second portion of the desired font object the second data set comprising second modification information related to the second guiding frame;
and
rendering the desired font object using at least the input data, the first data set, and the second data set, wherein the input data including information indicating the positions and sizes of the first and second portions of the desired font object are used in defining positioning and sizing of the first and second guiding frames, and wherein the rendering includes hinting of the first guiding frame based on the first modification information to, at least in part, control a position or size of at least a part of the first portion of the desired font object.
