Abstract

A system and method is illustrated for platform-independent rendering of a document in a web browser supporting a two-dimensional (2D) canvas. The system and method includes obtaining the document, wherein the document includes text characters, text elements, and associated style information including at least one font, determining that font metrics do not exist, and obtaining the font metrics for the at least one font, using the font metrics and the text elements to determine how the document is divided into page criteria, determining a font file does not exist, and obtaining the font file for the at least one font, and rendering the document by drawing glyphs associated with the text characters in the 2D canvas, using the font file and the page criteria, so that the at least one font and the page criteria are platform-independent.

Claims (74)

1. A computer implemented method for platform-independent rendering of a document in a web browser supporting a two-dimensional (2D) canvas, comprising:

obtaining from a server that includes a document repository and a fonts system the document, wherein the document includes text characters, text elements, and associated style information including at least one font;

parsing the document to identify at least one tag that groups a segment of text characters;

determining that font metrics associated with the segment of text characters do not exist;

obtaining from the fonts system the font metrics for the at least one font, wherein the font metrics identify at least a rendering position and a width of the segment of text characters;

using the font metrics and the text elements to determine how the document is divided into page criteria;

determining whether a font file associated with the segment of text characters exists;

in the event the font file associated with the segment of text characters does not exist, obtaining from the fonts system the font file for the at least one font;

in the event the font file associated with the segment of text characters does exists:

determining whether the font file of the web browser matches the font file from the fonts system;

in the event the font file of the web browser does not match the font file from the fonts system, obtaining from the fonts system the font file for the at least one font; and

rendering the document by drawing glyphs associated with the text characters in the 2D canvas, using the font file and the page criteria, so that the at least one font and the page criteria are platform-independent.

2. The method of claim 1 , wherein the text elements include at least one of paragraphs, spans, and the text characters.

3. The method of claim 2 , wherein the page criteria include at least one of glyphs, text runs, lines, and pages.

4. The method of claim 3 , wherein using the font metrics and the text elements to determine how the document is divided into the page criteria includes:

based on the font metrics and the style information, converting the text characters into the glyphs;

based on the spans and the glyphs, generating the text runs; and

based on the text runs, calculating a position of each of the glyphs within the lines and the pages on the 2D canvas.

5. The method of claim 1 , wherein the font file has information associated with glyphs defined for the at least one font.

6. The method of claim 1 , wherein for each of the glyphs, the font metrics are derived from the font file and include glyph geometry comprising height and weight.

7. The method of claim 1 , wherein obtaining the document includes:

obtaining a font list including the at least one font from the server;

obtaining default font metrics and a default font file associated with a default font of the font list from the server; and

obtaining the document from the server.

8. The method of claim 1 , wherein the font metrics are specified using eXtensible Markup Language (XML).

9. The method of claim 1 , wherein obtaining the font file for the at least one font includes retrieving the font file for the at least one font from a server through the use of a URL.

10. A system comprising:

a processor; and

a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions which when executed cause the processor to:

obtain a document from a document repository residing on a server, wherein the document includes text characters, text elements, and associated style information including at least one font, wherein the server includes a fonts system;

store the document;

parse the document to identify at least one tag that groups a segment of text characters;

determine that font metrics associated with segment of text characters do not exist;

obtain from the fonts system the font metrics for the at least one font, wherein the font metrics identify at least a rendering position and a width of the segment of text characters;

use the font metrics and the text elements to determine how the document is divided into page criteria;

determine whether a font file associated with the segment of text characters exists;

in the event the font file associated with the segment of text characters does not exist, obtain the font file for the at least one font;

in the event the font file associated with the segment of text characters does exists:

determine whether the font file of the web browser matches the font file from the fonts system;

in the event the font file of the web browser does not match the font file from the fonts system, obtain from the fonts system the font file for the at least one font; and

render the document by drawing glyphs associated with the text characters in a two-dimensional (2D) canvas using the font file and the page criteria, so that the at least one font and the page criteria are platform-independent.

11. The system of claim 10 , wherein the text elements include at least one of paragraphs, spans, and the text characters.

12. The system of claim 11 , wherein the page criteria include at least one of text runs, lines, and pages.

13. The system of claim 12 , wherein use the font metrics and the text elements to determine how the document is divided into the page criteria comprises:

based on the font metrics and the style information, convert the text characters into the glyphs;

based on the spans and the glyphs, generate the text runs; and

based on the text runs, calculate a position of each of the glyphs within the lines and the pages on the 2D canvas.

14. The system of claim 10 , wherein the instructions further cause the processor to:

obtain a font list including the at least one font from the server;

obtain default font metrics and a default font file associated with a default font of the font list from the server; and

a document retrieving module to obtain the document from the server.

15. The system of claim 10 , wherein obtain the font file for the at least one font includes retrieve the font file for the at least one font from the server through the use of a URL.

16. A machine-readable medium for platform-independent rendering of a document in a web browser supporting a two-dimensional (2D) canvas, the machine-readable medium including instructions embodied in a tangible, non-transitory, computer readable storage medium and comprising computer instructions for:

obtaining from a remote server that includes a document repository and a fonts system the document, wherein the document includes text characters, text elements, and associated style information including at least one font;

parsing the document to identify at least one tag that groups a segment of text characters;

determining that font metrics associated with the segment of text characters do not exist;

obtaining from the fonts system the font metrics for the at least one font, wherein the font metrics identify at least a rendering position and a width of the segment of text characters;

using the font metrics and the text elements to determine how the document is divided into page criteria;

determining whether a font file associated with the segment of text characters exists;

in the event the font file associated with the segment of text characters does not exist, obtaining from the fonts system the font file for the at least one font;

in the event the font file associated with the segment of text characters does exists:

determining whether the font file of the web browser matches the font file from the fonts system;

in the event the font file of the web browser does not match the font file from the fonts system, obtaining from the fonts system the font file for the at least one font; and

rendering the document by drawing glyphs associated with the text characters in the 2D canvas, using the font file and the page criteria, so that the at least one font and the page criteria are platform-independent.

17. The machine-readable medium of claim 16 , wherein the text elements include at least one of paragraphs, spans, and the text characters.

18. The machine-readable medium of claim 17 , wherein the page criteria include at least one of text runs, lines, and pages.

19. The machine-readable medium of claim 18 , wherein using the font metrics and the text elements to determine how the document is divided into the page criteria includes:
