| public int | charWidth(char ch)Returns the advance width of the specified char of the Font describing
this FontMetricsImpl object.
if (ch < 256) {
return widths[ch];
}
return (int) (getFontPeer().charWidth(ch) * scaleX);
|
| public int | getAscent()Returns the ascent of the Font describing this FontMetricsImpl object.
return this.ascent;
|
