Abstract

There is provided a method for preloading the glyphs required to display the content of a system. In accordance with an embodiment of the present technique, only those glyphs which are present in the system upon startup or synchronization of an electronic device are preloaded. The glyphs present upon startup or synchronization of the electronic device may be determined by scanning the system. In an illustrated embodiment, scanning the system may include analyzing models and views to determine the glyphs present in the system.

Claims

1. A method for loading glyphs, comprising:

determining, by a portable hand-held device during startup of the portable hand-held device, glyphs present in display information stored in non-volatile memory of the portable hand-held device based on character and character rendering attributes defined by the display information, wherein determining comprises scanning models and views stored on the portable hand-held device to determine the glyphs present in the display information; and

preloading, from the non-volatile memory to a volatile memory of the portable hand-held device, only the glyphs having characters and attributes defined by the display information present on the portable hand-held device during startup of the portable hand-held device.

2. The method of claim 1, wherein the models comprise characters including letters, numbers, or symbols, or a combination thereof.

3. The method of claim 1, wherein the views comprise attributes including typeface, size, style, or color, or a combination thereof.

4. The method of claim 1, comprising compiling a list of the glyphs based on the display information scan, using an external manager program, or a combination of both.

5. A portable hand-held device, comprising:

a non-volatile storage device that stores glyphs for display on the portable hand-held device;

a processor that, during startup the portable hand-held device, scans for displayable information stored on the portable hand-held device to determine which glyphs of the stored glyphs are required to display such displayable information; and

a volatile memory device onto which only the required glyphs are preloaded from the nonvolatile storage device upon powering up the portable hand-held device.

6. The portable hand-held device of claim 5, comprising a display operably coupled to the processor and configured to display the displayable information.

7. The portable hand-held device of claim 5, wherein the displayable information comprises a view and a model containing information defining the required glyphs.

8. The portable hand-held device of claim 5, wherein the non-volatile storage device comprises a hard drive, a flash drive, or a type of read-only memory, or a combination thereof.

9. The portable hand-held device of claim 5, wherein the volatile memory device comprises a random access memory.

10. A method for preloading glyphs, comprising:

scanning, by a portable hand-held device during startup of the portable hand-held device, a view stored on a non-volatile storage device of a portable hand-held device for display attributes;

scanning, by the portable hand-held device during startup of the portable hand-held device, a model stored on the non-volatile storage device for display data, including one or more characters, and the view with which the display data is associated;

compiling, by the portable hand-held device, a list of display glyphs based on the characters and the display attributes; and

copying, by the portable hand-held device, the glyphs on the list from the non-volatile storage device onto a system memory of the portable hand-held device.

11. The method of claim 10, wherein the non-volatile storage device comprises a hard drive, a flash drive, or a type of read-only memory, or a combination thereof.

12. The method of claim 10, wherein the system memory comprises a random access memory.

13. The method of claim 10, wherein the display attributes comprise typeface, size, style, or color, or a combination thereof.

14. The method of claim 10, wherein the characters comprises letters, numbers, or symbols, or a combination thereof.

15. A non-transitory machine-readable medium, comprising code executable to perform tasks of:

scanning, during startup of a portable hand-held device, for individual glyphs present in display information stored in non-volatile memory on the portable hand-held device, each of the individual glyphs corresponding to a character and having one or more display attributes; and

preloading, from the non-volatile memory to a volatile memory of the portable hand-held device during startup of the portable hand-held device, only the individual glyphs present in the display information.

16. The non-transitory machine-readable medium of claim 15, comprising code executable to perform the task of compiling a list of the individual glyphs based on the scan.

17. The non-transitory machine-readable medium of claim 15, wherein scanning comprises scanning models and views to determine the individual glyphs present on the portable hand-held device.

18. The non-transitory machine-readable medium of claim 17, wherein the models comprise characters including letters, numbers, or symbols, or a combination thereof.

19. The non-transitory machine-readable medium of claim 17, wherein the views comprise attributes including typeface, size, style, or color, or a combination thereof.
