ABSTRACT:
Methods and apparatus, including computer program products, implementing and using techniques for rendering a glyph to make it more readable. In an implementation, a glyph associated with a font to be rendered at a size is received, and a set of initial density values is calculated to provide one density value for each of a set of device pixels to represent the glyph. An initial adjustment value is calculated for the glyph. For one or more of the device pixels in the set of device pixels, a length of an edge of the glyph that passes through the device pixel is calculated. For one or more of the device pixels, the initial density value is adjusted by a final adjustment value, the final adjustment value based upon the initial adjustment value and the length of the edge of the glyph passing through the device pixel.
