2.3.6.7 EmfPlusSetTextContrast Record

The EmfPlusSetTextContrast record specifies text contrast according to the gamma correction value.

Type (2 bytes): An unsigned integer that identifies this record type as EmfPlusSetTextContrast from the RecordType enumeration. The value MUST be 0x4020.

Flags (2 bytes): An unsigned integer that provides information about how the operation is to be performed, and about the structure of the record.

X	X	X	X	TextContrast

X (1 bit): Reserved and MUST be ignored.

TextContrast (12 bits): The gamma correction value X 1000, which will be applied to subsequent text rendering operations. The allowable range is 1000 to 2200, representing text gamma values of 1.0 to 2.2.

Size (4 bytes): An unsigned integer that specifies the 32-bit-aligned number of bytes in the entire record, including the 12-byte record header and record-specific data. For this record type, the value MUST be 0x0000000C.

DataSize (4 bytes): An unsigned integer that specifies the 32-bit-aligned number of bytes of record-specific data that follows. For this record type, the value MUST be 0x00000000.

See section 2.3.6 for the specification of additional property record types.
