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 portable electronic device, comprising:

at least one non-volatile memory device storing at least one symbol that is capable of being presented at a display of the portable electronic device;

at least one processor configured to, during a startup of the portable electronic device;

i) analyze one or more views that are to be presented at the display, wherein the one or more views include at least one attribute for determining a manner in which the at least one symbol is to be presented in the one or more views at the display,

ii) generate, based on the at least one attribute and the at least one symbol, a list of glyphs; and

iii) preload, from the at least one non-volatile memory device, at least one glyph from the list of glyphs into a volatile memory device of the portable electronic device.

2. The portable electronic device of claim 1, wherein the at least one non-volatile memory device stores the at least one symbol and the one or more views.

3. The portable electronic device of claim 1, wherein the at least one attribute includes a font, a size, a style, or a color.

4. The portable electronic device of claim 1, wherein, subsequent to the startup of the portable electronic device, the one or more views are presented at the display.

5. The portable electronic device of claim 4, wherein the one or more views include a menu view, a system bar, a photo title view, a contact name view, or a song title view.

6. The portable electronic device of claim 1, wherein the at least one symbol includes data, and the portable electronic device utilizes the data to select a specific view from the one or more views.

7. The portable electronic device of claim 1, wherein the least one glyph is generated from only the list of glyphs.

8. A method performed by a portable electronic device comprising at least one non-volatile memory device storing at least one symbol capable of being presented at a display of the portable electronic device, the method comprising:

i) during a startup of the portable electronic device;

a) scanning for one or more views that are to be presented at the display, wherein the one or more views include at least one attribute for determining a manner in which the at least one symbol is to be presented in the one or more views at the display,

b) generating, based on the at least one attribute and the at least one symbol, a list of glyphs, and

c) pre-loading, from the at least one non-volatile memory device, at least one glyph from the list of glyphs into at least one volatile memory device of the portable electronic device; and

ii) reading the at least one glyph.

9. The method of claim 8, further comprising:

presenting the at least one glyph at the display.

10. The method of claim 8, wherein:

i) the at least one glyph is associated with an outline font,

ii) the outline font comprises a single glyph for a first typeface character in the outline font, and

iii) the single glyph is resized based on a font size.

11. The method of claim 8, wherein the least one glyph is generated from only the list of glyphs.

12. The method of claim 8, wherein the list of glyphs does not include every glyph that is stored in the at least one non-volatile memory device.

13. The method of claim 8, wherein the at least one attribute includes a font, a size, a style, or a color.

14. The method of claim 8, wherein, subsequent to the startup of the portable electronic device, the one or more views are presented at the display.

15. The method of claim 8, wherein, subsequent to the startup of the portable electronic device, the method further comprises:

pre-loading another glyph from the list of glyphs into the at least one volatile memory device, wherein the another glyph is distinct from the at least one glyph.

16. The method of claim 15, further comprising:

displaying the another glyph at the display.

17. The method of claim 8, wherein the one or more views include a menu view, a system bar, a photo title view, a contact name view, or a song title view.

18. The method of claim 8, wherein the at least one symbol is associated with a language.

19. The method of claim 18, wherein the language is associated with at least one of English, French, Spanish, Arabic, or Chinese.

20. At least one non-transitory computer readable storage medium containing instructions, that in response to being executed by at least one processor of a portable electronic device, cause the portable electronic device to:

during a startup of the portable electronic device, wherein the portable electronic device comprises at least one non-volatile memory device storing at least one symbol that is capable of being presented at a display of the portable electronic device;

a) scan for one or more views that are to be presented at the display, wherein the one or more views include at least one attribute for determining a manner in which the at least one symbol is to be presented in the one or more views at the display,

b) generate, based on the at least one attribute and the at least one symbol, a list of glyphs, and

c) preload, from the at least one non-volatile memory device, at least one glyph from the list of glyphs into at least one volatile memory device of the portable electronic device.

21. A portable electronic device, comprising:

at least one non-volatile memory device storing at least one symbol that is capable of being presented at a display of the portable electronic device;

at least one volatile memory device; and

at least one processor coupled to the at least one non-volatile memory device and the at least one volatile memory device, wherein the at least one processor is configured to, during a startup of the portable electronic device;

a) scan for one or more views that are to be presented at the display, wherein the one or more views include at least one attribute for determining a manner in which the at least one symbol is to be presented in the one or more views at the display, and

b) generate, from the at least one attribute and the at least one symbol, a list of glyphs.

22. The portable electronic device of claim 21, wherein the at least one volatile memory device further causes the portable electronic device to:

preload, from the at least one non-volatile memory device, at least one glyph from the list of glyphs.

23. The portable electronic device of claim 21, wherein the at least one non-volatile memory device stores the one or more views.

24. The portable electronic device of claim 22, wherein the at least one attribute includes a font, a size, a style, or a color.

25. The portable electronic device of claim 22, wherein, subsequent to the startup of the portable electronic device, the one or more views are presented at the display.

26. The portable electronic device of claim 22, wherein the at least one symbol includes data, and the portable electronic device utilizes the data to select a specific view from the one or more views.
