The Kerning Pair Table

The kerning pair table record is not present if the _KerningPairs record in the metrics is zero. If it is present, the code points are words, not bytes. This table should be sorted by kpChar1 and kpChar2 order to allow binary searches.

typedef struct _KERNPAIRTABLE {
        ULONG   ulIdentity;
        ULONG   ulSize;
        CHAR    cFirstpair;
}KERNPAIRTABLE;

typedef struct _KERNPAIRS {
        SHORT   sFirstChar;
        SHORT   sSecondChar;
        SHORT   sKerningAmount;
}KERNINGPAIRS;

Where:

ulIdentity

3
ulSize
10
sFirstChar
First character of the kerning pair.
sSecondChar
Second character of the kerning pair.
sKerningAmount
Kerning value. Positive values increase the inter-character spacing while negative values bring the characters closer together.

Outline Data Format

Fonts defined by outlines (vectors) may contain any of these graphics orders:

• Line at given position (GLINE) 
  Line at current position (GCLINE)
  
  Relative line at given position (GRLINE)
  
  Relative line at current position (GCRLINE)
  
  Fillet at given position (GFLT)
  
  Fillet at current position (GCFLT)
  
  Sharp fillet at given position (GSFLT)
  
  Sharp fillet at current position (GCSFLT)
  
  Bezier curve at given position (GBEZ)
  
  Bezier curve at current position (GCBEZ)
  
  No operation (GNOP1)
  
  Comment (GCOMT)
  
  End of symbol definition (GESD).

  The maximum length of the data in these orders is 255 bytes. The drawing order code and the length fields are not included in the length count.

  The size of each outline font definition must not be longer than 64KB.
