The ABC structure contains the width of a character in a TrueType font.
abcA
Specifies the “A” spacing of the character. The “A” spacing is the distance to add to the current position before drawing the character glyph.
abcB
Specifies the “B” spacing of the character. The “B” spacing is the width of the drawn portion of the character glyph.
abcC
Specifies the “C” spacing of the character. The “C” spacing is the distance to add to the current position to provide white space to the right of the character glyph.
The total width of a character is the summation of the “A”, “B”, and “C” spaces. Either the “A” or the “C” space could be negative, to indicate underhangs or overhangs.
