maxp — Maximum Profile (OpenType 1.8.2)

This table establishes the memory requirements for this font. Fonts with CFF data must use Version 0.5 of this table, specifying only the numGlyphs field. Fonts with TrueType outlines must use Version 1.0 of this table, where all data is required.

Version 0.5

Type	Name	Description
Fixed	version	0x00005000 for version 0.5 (Note the difference in the representation of a non-zero fractional part, in Fixed numbers.)
uint16	numGlyphs	The number of glyphs in the font.

Version 1.0

Type	Name	Description
Fixed	version	0x00010000 for version 1.0.
uint16	numGlyphs	The number of glyphs in the font.
uint16	maxPoints	Maximum points in a non-composite glyph.
uint16	maxContours	Maximum contours in a non-composite glyph.
uint16	maxCompositePoints	Maximum points in a composite glyph.
uint16	maxCompositeContours	Maximum contours in a composite glyph.
uint16	maxZones	1 if instructions do not use the twilight zone (Z0), or 2 if instructions do use Z0; should be set to 2 in most cases.
uint16	maxTwilightPoints	Maximum points used in Z0.
uint16	maxStorage	Number of Storage Area locations.
uint16	maxFunctionDefs	Number of FDEFs, equal to the highest function number + 1.
uint16	maxInstructionDefs	Number of IDEFs.
uint16	maxStackElements	Maximum stack depth. (This includes Font and CVT Programs, as well as the instructions for each glyph.)
uint16	maxSizeOfInstructions	Maximum byte count for glyph instructions.
uint16	maxComponentElements	Maximum number of components referenced at “top level” for any composite glyph.
uint16	maxComponentDepth	Maximum levels of recursion; 1 for simple components.
