_MAPTABLE structure

Description

The MAPTABLE structure is one of the structures used to define the contents of glyph translation table files (.gtt files).

Members

`dwSize`

Specifies the size, in bytes, of the MAPTABLE structure, including the Trans array.

`dwGlyphNum`

Specifies the number of elements in the Trans array.

`Trans`

Is an array of TRANSDATA structures.

Remarks

A .gtt file's MAPTABLE structure, which contains a glyph mapping table, is accessed by a pointer in the file's UNI_GLYPHSETDATA structure. The table maps glyph handles to the character codes or commands that must be sent to the printer in order to print glyphs.
