Abstract: Methods and apparatus implementing and using techniques for rendering a stroke (e.g., a line or glyph). An initial adjustment value can be calculated for the stroke, and an offset amount calculated based on the initial adjustment value, such that a minimum number of device pixels will be marked by the stroke after adjusting density values of device pixels representing the stroke. A high resolution representation of the stroke (e.g., a set of device pixels each having an initial density value) is rendered so that one or more edges of the stroke is offset from a device resolution grid by the offset amount. A length of an edge of the stroke that passes through a device pixel can be calculated, and the density value of the device pixel adjusted by a final adjustment value based on the initial adjustment value and the length of the edge of the stroke.

Abstract: Methods and apparatus implementing and using techniques for scaling a character having stems. A character including stems and having an associated output resolution and an associated bit depth can be received. The counters defined by the stems can be grouped into one or more chains of counters. The stems of the character can be aligned based on a stem alignment policy while the chains of counters are balanced based on the output resolution. A pixel map can be created at the output resolution and the output bit depth based on the aligned stems.

Abstract: Methods, apparatus, including computer program products, and systems implement and use techniques for rendering glyphs. A plurality of glyphs to be rendered are received. For each glyph, an anti-aliasing procedure is selected to render the glyph. The anti-aliasing procedure is selected from a first anti-aliasing procedure and one or more alternative anti­aliasing procedures. The anti-aliasing procedure for each glyph is selected based on the glyph.
