Abstract

Techniques are described herein for causing a browser to render text of a web page in a non-native font that do not require the browser to obtain font rendering information for characters defined in the non-native font that are not rendered on the web page in the non-native font. According to one embodiment, for example, a subset of the characters defined in a non-native font that are to be rendered on a web page in the non-native font is determined. Font rendering information is obtained from a remote resource for just the subset of characters and not for characters defined in the non-native font that are not in the subset. The font rendering information obtained for the subset is used to render each character in the subset on the web page in the non-native font.

Claims

1. A method comprising:

determining a subset of characters defined in a particular font that are to be rendered on a web page in the particular font;

obtaining, from a remote resource, font information for the particular font for just the subset of characters and not for characters defined in the particular font that are not in the subset; and

based on the obtained font information, causing each character in the subset to be rendered on the web page in the particular font;

wherein the method is performed by a computing device.

2. The method according to claim 1, wherein determining the subset of characters includes analyzing text of the web page to determine the subset of characters.

3. The method according to claim 1, wherein obtaining the font information for just the subset of characters includes obtaining the font information from a remote server.

4. The method according to claim 3, wherein obtaining the font information from a remote server includes sending a request to the remote server, the request comprising (a) an identifier of the particular font and (b), for each character in the subset, an identifier of the character.

5. The method according to claim 1, wherein the obtained font information comprises font drawing information for just the subset of characters and not for characters defined in the particular font that are not in the subset.

6. The method according to claim 5, wherein the font drawing information comprises, for each character in the subset, vector graphics drawing information for the character.

7. The method according to claim 6, wherein the vector graphics drawing information for a character is based on a vector graphics language description of the character.

8. The method according to claim 1, wherein causing each character in the subset to be rendered on the web page in the particular font includes replacing text of the web page with browser-executable font drawing instructions which, when executed or interpreted by a browser, cause the replaced text to be rendered on the web page in the particular font.

9. The method according to claim 8, wherein the browser-executable font drawing instructions comprise instructions for drawing the subset of characters on one or more browser-supported vector graphics drawing surfaces rendered on the web page.

10. The method according to claim 1, wherein the method is performed by one or more scripts executed by the computing device that are embedded in or linked by the web page.

11. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 1.

12. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 2.

13. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 3.

14. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 4.

15. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 5.

16. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 6.

17. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 7.

18. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 8.

19. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 9.

20. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 10.

21. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 11.

22. A computing device comprising:

first logic for determining a subset of characters defined in a particular font that are to be rendered on a web page in the particular font;

second logic operatively coupled to the first logic for obtaining, from a remote resource, font information for the particular font for just the subset of characters and not for characters defined in the particular font that are not in the subset; and

third logic operatively coupled to the first and second logic for causing, based on the obtained font information, each character in the subset to be rendered on the web page in the particular font.

23. The computing device of claim 22, wherein the web page is stored in one or more non-transitory computer-readable media of the computing device;

and wherein the first, second, and third logic are implemented by one or more scripts embedded in or linked by the stored web page.
