System and method for anti-aliasing of text overlays on electronic images

A system for anti-aliasing text overlays on electronic images comprising:

• a text-font manager for loading a selected background color and selected font data, said font data consisting of font type, font size, and font color;
• and for obtaining a text string for said text overlay;
• a graphics manager coupled to said text-font manager for retrieving bit-mapped data for said selected font data and said text string, and for retrieving a current pixel from a plurality of pixels of said bit-mapped data;
• and
• an anti-aliasing module coupled to said graphics manager for adjusting said current pixel based upon said bit-mapped data and a corresponding image data pixel in said electronic image, producing an adjusted current pixel, and for overlaying said adjusted current pixel onto said corresponding image data pixel in said electronic image.

A system for anti-aliasing text overlays on electronic images comprising:

• means for loading a selected background color and selected font data wherein said font data consists of font type, font size, and font color;
• means for obtaining a text string for said text overlay;
• means for retrieving bit-mapped data for said selected font data and said text string;
• means for retrieving a current pixel from a plurality of pixels of said bit-mapped data;
• means for adjusting said current pixel based upon said bit-mapped data and a corresponding image data pixel in said electronic image, producing an adjusted current image;
• and
• means for overlaying said adjusted current pixel onto said corresponding image data pixel in said electronic image.

A computer-readable medium comprising program instructions for anti-aliasing text overlays on electronic images by performing the steps of:

• loading a selected background color and selected font data, said front data consisting of font type, font size, and font color;
• obtaining a text string for said text overlay;
• retrieving bit-mapped data for said selected font data and text string;
• retrieving a current pixel from a plurality of pixels of said bit-mapped data;
• adjusting said current pixel based upon said bit-mapped data and a corresponding pixel in said electronic image, producing an adjusted current pixel;
• and
