Abstract
Abstract Among other things, one or more techniques and/or systems are disclosed for rendering a glyph. Rendering data for the glyph can be received, such as size, shape, color, etc., along with first sub-pixel position for initially rendering the glyph on a display. A first rendering quality can be identified for the first sub-pixel position and second rendering quality can be identified for a second sub-pixel position, which may comprise an alternate rendering position. A sub-pixel position shift can be selected for the glyph based at least upon a comparison of the first and second rendering qualities. The sub-pixel position shift can comprise a difference between the first sub-pixel position and the second sub-pixel position, where the second rendering quality is selected/preferable over the first rendering quality. The glyph can be rendered by applying the selected sub-pixel position shift.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
132 words
A method for rendering a glyph, comprising: receiving the glyph and a first sub-pixel position for the glyph; identifying a rendering quality for the glyph at a second sub-pixel position based at least upon a determined brightness value aspect for at least a portion of the glyph to be rendered at the second sub-pixel position, a determined contrast value aspect for the at least a portion of the glyph and a determined typographical preference aspect for the at least a portion of the glyph; selecting a sub-pixel position shift for the glyph based at least upon the rendering quality, the sub-pixel position shift comprising a difference between the first sub-pixel position and the second sub-pixel position; and rendering the glyph on a display comprising applying the sub-pixel position shift to the glyph.
Claim 2
Independent Claim
132 words
A method for rendering a glyph, comprising: receiving the glyph and a first sub-pixel position for the glyph; identifying a rendering quality for the glyph at a second sub-pixel position based at least upon a determined brightness value aspect for at least a portion of the glyph to be rendered at the second sub-pixel position, a determined contrast value aspect for the at least a portion of the glyph and a determined typographical preference aspect for the at least a portion of the glyph; selecting a sub-pixel position shift for the glyph based at least upon the rendering quality, the sub-pixel position shift comprising a difference between the first sub-pixel position and the second sub-pixel position; and rendering the glyph on a display comprising applying the sub-pixel position shift to the glyph.
