Abstract

At least certain embodiments of the present disclosure include a font file having graphic image files. In one embodiment, the font includes a set of glyphs and the font file includes a set of predetermined information of each glyph and graphic image data of each glyph. The graphic image data contains a graphic image of the corresponding glyph, which may be a multi-color glyph.

Claims

1. A machine-readable storage medium storing executable program instructions which when executed by a data processing system cause the data processing system to perform a method comprising:

retrieving a set of glyph metrics of a glyph from a font file;

causing a graphic engine to set aside a blank region on a printing medium based on the set of glyph metrics;

retrieving graphic image data of the glyph from the font file; and

causing the graphic engine to draw an image of the glyph in the blank region on the printing medium according to the graphic image data.

2. The machine-readable storage medium of claim 1, wherein the method further comprises:

retrieving a color bitmap table of the glyph from the font file, wherein the color bitmap table contains a reference to the graphic image data of the glyph, and retrieving the graphic image data of the glyph from the font file comprises

using the reference to access the graphic image data.

3. The machine-readable storage medium of claim 1, wherein format of the graphic image data of the glyph is Joint Photographic Expert Group format (JPEG).

4. The machine-readable storage medium of claim 1, wherein the glyph is a multi-color glyph.

5. A computer-implemented method, comprising:

storing a font file of a font in a computer-readable storage medium, the font comprising a plurality of multi-color glyphs, and the font file comprising a plurality of empty vector lists associated with the plurality of multi-color glyphs and graphic image data, the graphic image data containing a multi-color image of a each of the plurality of multi-color glyphs; and

printing the plurality of multi-color glyphs of the font on a printing medium according to the plurality of empty vector lists and the graphic image data.

6. The method of claim 5, wherein the graphic image data is of different graphic formats.

7. The method of claim 5, wherein the font file further comprises a plurality of references to refer to locations of the graphic image data.

8. The method of claim 5, wherein the font file further comprises a plurality of representations of each of the plurality of multi-color glyphs, wherein each of the plurality of representations is optimized for a distinct resolution.

9. The method of claim 5, wherein printing the plurality of multi-color glyphs of the font comprises:

for each of the plurality of multi-color glyphs, setting aside a blank region on the printing medium according to one of the plurality of empty vector lists, which corresponds to a respective multi-color glyph.

10. The method of claim 9, wherein printing the plurality of multi-color glyphs of the font further comprises:

drawing an image of the respective multi-color glyph in the blank region according to at least part of the graphic image data corresponding to the respective multi-color glyph.

11. The method of claim 5, further comprising:

updating the font file by replacing at least part of the graphic image data with new graphic image data of multi-color glyphs.

12. An apparatus comprising:

a font parser to access a font file to retrieve a plurality of glyph metrics of a glyph and a color bitmap table of the glyph;

a layout engine to receive the color bitmap table of the glyph from the font parser and to retrieve graphic image data of the glyph from the computer-readable storage medium using a reference to the graphic image data in the color bitmap table; and

a graphic engine to receive the plurality of glyph metrics of the glyph from the font parser and to set aside a blank region on a printing medium according to the plurality of glyph metrics.

13. The apparatus of claim 12, wherein the graphic engine further draws an image of the glyph in the blank region on the printing medium according to the graphic image data in response to an instruction from the layout engine.

14. The apparatus of claim 13, wherein the graphic engine further draws the image of the glyph in a plurality of predetermined colors according to the graphic image data.

15. The apparatus of claim 12, wherein the plurality of glyph metrics of the glyph includes an origin, an advance, and a bounding box of the glyph.

16. The apparatus of claim 12, further comprising:

a computer-readable storage medium to store the font file.

17. The apparatus of claim 12, further comprising:

a network interface to interface with a network in order to access the font file remotely.

18. The apparatus of claim 12, further comprising:

a printer to print the glyph on the printing medium in response to instructions from the graphic engine, wherein the printing medium includes at least one of a physical printing medium and a digital printing medium.

19. An apparatus comprising:

means for storing a font file of a font having a plurality of glyphs, the font file comprising graphic image data of the plurality of glyphs;

means for determining a size, an outline, and a location of a glyph of the plurality of glyphs using the font file; and

means for drawing an image of the glyph in the size determined and at the location determined.

20. The apparatus of claim 19, wherein the glyph is a multi-color glyph.

21. The apparatus of claim 19, wherein the graphic image data is of different formats.

22. The apparatus of claim 19, further comprising:

means for printing the image of the glyph on a printing medium.
