16	Byte	Reserved
2	Integer	Number of characters in the font
2	Integer	Base height
4	Integer	Flags: 1 - filled characters, all polylines are closed
4	Integer	Offset (in bytes) from the begining of file to the data of first character
1	Integer	0 - can be spline segments between points; 1 - only linear segments
31	Byte	Reserved

Index table, size = <Number of font characters> * <6 bytes>

Size (bytes)	Data type	Description
2	Integer	Code of character
4	Integer	Offset (in bytes) from start of first character data
