Abstract

A system and method for dilating a glyph for glyph rendering is described. The method includes receiving information including at least one of an element value of a rendering matrix, a glyph characteristic, a display background characteristic, an application characteristic, a display characteristic, and a graphics engine characteristic. The method further includes determining a dilation factor value from the received information. The method also includes dilating the outline of the glyph using the determined dilation factor.

Claims

1. A method for dilating an outline of a glyph, comprising:

receiving an information including at least one of;

an element value of a rendering matrix;

a glyph characteristic;

a display background characteristic;

an application characteristic;

a display characteristic; and

a graphics engine characteristic;

determining an at least one dilation factor from the information; and

dilating the outline of the glyph using the at least one dilation factor.

2. The method of claim 1, wherein the information includes at least one display characteristic, the display characteristic including orientation information of a display for rendering the glyph or an amount of ambient light in a room.

3. The method of claim 2, wherein the information is received by a sensor, the sensor being an accelerometer and/or an ambient light sensor.

4. The method of claim 1, wherein the at least one dilation factor comprises a first dilation factor and a second dilation factor.

5. The method of claim 4, wherein the first dilation factor is for dilation in the horizontal direction and the second dilation factor is for dilation in the vertical direction.

6. The method of claim 1, wherein the at least one dilation factor comprises only one dilation factor, the dilation factor for dilation in the horizontal direction and dilation in the vertical direction.

7. The method of claim 1, further comprising:

creating a bitmapped image from the dilated outline;

creating the glyph from the bitmapped image; and

displaying the glyph on a display.

8. The method of claim 1, wherein the at least one dilation factor is an at least one function.

9. The method of claim 8, further comprising creating the at least one function from the information.

10. A system for dilating an outline of a glyph, comprising:

a receiving module to receive an information including at least one of;

an element value of a rendering matrix;

a glyph characteristic;

a display background characteristic;

an application characteristic;

a display characteristic; and

a graphics engine characteristic;

a determination module to determine an at least one dilation factor from the information; and

a dilation module to dilate the outline of the glyph using the at least one dilation factor.

11. The system of claim 10, wherein the information includes at least one display characteristic, the display characteristic including orientation information of a display for rendering the glyph or an amount of ambient light in a room.

12. The system of claim 11, wherein the information is received by a sensor, the sensor being an accelerometer and/or an ambient light sensor.

13. The system of claim 10, wherein the at least one dilation factor comprises a first dilation factor and a second dilation factor.

14. The system of claim 13, wherein the first dilation factor is for dilation in the horizontal direction and the second dilation factor is for dilation in the vertical direction.

15. The system of claim 10, wherein the at least one dilation factor comprises only one dilation factor, the dilation factor for dilation in the horizontal direction and dilation in the vertical direction.

16. The system of claim 10, further comprising:

a creation module to create a bitmapped image from the dilated outline;

a conversion module to create the glyph from the bitmapped image; and

a display module to display the glyph on a display.

17. The system of claim 10, wherein the at least one dilation factor is an at least one function.

18. The system of claim 17, further comprising a function creation module to create the at least one function from the information.

19. A machine-readable medium having executable instructions to cause a processor to perform a method for dilating a glyph, comprising:

receiving an information including at least one of;

an element value of a rendering matrix;

a glyph characteristic;

a display background characteristic;

an application characteristic;

a display characteristic; and

a graphics engine characteristic;

determining an at least one dilation factor from the information; and

dilating the outline of the glyph using the at least one dilation factor.

20. The machine-readable medium of claim 19, wherein the information includes at least one display characteristic, the display characteristic including orientation information of a display for rendering the glyph or an amount of ambient light in a room.

21. The machine-readable medium of claim 20, wherein the information is received by a sensor, the sensor being an accelerometer and/or an ambient light sensor.

22. The machine-readable medium of claim 19, wherein the at least one dilation factor comprises a first dilation factor and a second dilation factor.

23. The machine-readable medium of claim 22, wherein the first dilation factor is for dilation in the horizontal direction and the second dilation factor is for dilation in the vertical direction.

24. The machine-readable medium of claim 19, wherein the at least one dilation factor comprises only one dilation factor, the dilation factor for dilation in the horizontal direction and dilation in the vertical direction.

25. The machine-readable medium of claim 19, further comprising:

creating a bitmapped image from the dilated outline;

creating the glyph from the bitmapped image; and

displaying the glyph on a display.

26. The machine-readable medium of claim 19, wherein the at least one dilation factor is an at least one function.

27. The machine-readable medium of claim 26, further comprising creating the at least one function from the information.

28. A system for displaying a glyph on a display of an electronic device, comprising:

means for creating an outline of the glyph from a character information, wherein the glyph represents the character;

means for receiving an information including at least one of;

an element value of a rendering matrix;

a glyph characteristic;

a display background characteristic;

an application characteristic;

a display characteristic; and

a graphics engine characteristic;

means for determining an at least one dilation factor from the information;

means for dilating the outline of the glyph using the at least one dilation factor;

means for creating a bitmapped image from the dilated outline;
