Abstract
In one aspect, the subject disclosure can be embodied in a method for rendering glyphs using circular arcs. A first Bezier curve defining a portion of a glyph outline is approximated using a second Bezier curve that represents a Bezier approximation of a circular arc. An upper bound for the approximation error is estimated based on a maximum distance between the two Bezier curves within a two-dimensional coordinate space. The first Bezier curve is converted to the circular arc approximated using the second Bezier curve for the portion of the glyph outline within the two-dimensional coordinate space, based on the estimated upper bound of the approximation error. The portion of the glyph outline is then displayed within an area of the display.
