ABC Structure

 

The latest version of this topic can be found at ABC Structure.

The ABC structure contains the width of a character in a TrueType font.

typedef struct _ABC { /* abc */  
    int abcA;  
    UINT abcB;  
    int abcC;  
} ABC;  

Parameters

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 can be negative to indicate underhangs or overhangs.
