Creating and Editing Fonts

Thinning is an erosion and reduction process that erases green and yellow
pixels from the edges of the taught character. Thinning is used only for font
teaching and editing.
When the Teach function is used, the green and yellow portions of the
character pattern are copied from the black and white portions of the printed
character image. They are then thinned down based on the G Thin and Y
Thin settings. These settings range from 1 (minimum thinning) to 5
(maximum thinning).

The currently selected thinning settings are stored in the font file, so they will
remain in effect whenever the Teach function is subsequently used for any
character in the font.
