Abstract:
1. A computer-implemented method for rendering glyphs using circular arcs, the method comprising: approximating, by a computing device, a first Bezier curve defining a portion of a glyph outline to be rendered on a display of the computing device, using a second Bezier curve representing a Bezier approximation of a circular arc, the second Bezier curve having the same endpoints as the first Bezier curve; estimating an upper bound for an approximation error based on a maximum distance between the first Bezier curve and the second Bezier curve within a two-dimensional coordinate space; converting the first Bezier curve 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; and displaying the portion of the glyph outline within an area of the display based on the conversion.
