•
The character data follows these header bytes. Characters are represented as raster data and the data bytes
are used to build up an image of the character from left to right and from top to bottom, according to the
character width and height settings.
•
Format (UB) - 15 specifies TrueType font.
•
Continuation (B) - specifies whether the character data represents a new character (0) or is a continuation of
the character described by the previous character descriptor block (non-zero). If the continuation byte is non-
zero the bytes following it are interpreted as character data.
•
Descriptor size (UB) - specifies the character descriptor size in bytes.
•
Class (UB) - indicates the character format.

•
Character data size (UI) - should be the same value as (the character data size + Glyph ID + TrueType Glyph
data) size.
•
Glyph ID (UI) - specifies the ID number for glyph data, which is used by the TrueType font scaler.
•
TrueType Glyph data - includes the data segment which is associated with the given character as found in the
glyph table of the original TrueType font file.
•
Checksum (UB) - should be a value which, when added to "Character data + Glyph ID + TrueType Glyph
data" size, produces a zero result.
