ABSTRACT:
A system and method for anti-aliasing of text overlays on electronic images comprises a text-font manager for loading background color and selected font data which includes font type, font size, and font color, and for obtaining a text string for overlay on the electronic image. The invention also includes a graphics manager for retrieving bit-mapped data for the selected font data and text string and for retrieving current pixel information from the bit-mapped data. The invention further comprises an anti-aliasing module for adjusting the inactive pixels of each character of the character text string based upon the surrounding pixels in the bit-mapped data. The anti-aliasing module overlays the electronic image with the active and adjusted text character pixels. The image merged with text is saved in memory and/or displayed on the electronic imaging display device.
