void | accrueXAdvance (const double xAdv) |
Sum up the individual x advances of each glyph: | |
void | setYMin (const double yMin) |
Keep a running tab on the minimum y value (descent) from all glyphs: | |
void | setYMax (const double yMax) |
Keep a running tab on the maximum y value (ascent) from all glyphs: | |
const double | getXAdvance () |
const double | getYMin () |
const double | getYMax () |
const double | getLineSpacing () |
Line spacing is just the maximum ascent minus the maximum descent multiplied by the line spacing factor: | |
