ABSTRACT:
A computer-implemented method for spacing characters rendered from a digital font at an output pointsize. The font has first spacing metrics for a small pointsize and for a different large pointsize. The method includes calculating a separation by interpolating the small pointsize metrics and the large pointsize metrics and spacing the pair as a function of the calculated separation. Embodiments may include the following features. The font has spacing metrics for at least three different pointsizes. The spacing metrics include left sidebearings, right sidebearings, or kerning values. A kerning value for a character pair is generated by interpolating a first kerning value at a small pointsize and a second kerning value at a large pointsize to the output pointsize. The invention also features a computer program on a computer-readable medium having instructions for rendering characters and two sets of spacing metrics at two different pointsizes. The invention also features a computer program having instructions for rendering a set of characters and a set of kerning values for all pairs consisting of one character from the set of characters and the space character.
