The Control-Value Table
The control-value table, with a tag name of'cvt ', is an optional table that can be used by fonts that contain instructions. This table contains data (control values) used by the instructions. Each entry in this table is 4 bytes long. The number of values in the table can be computed by dividing the length of the table by 4. The length of the table is found in the directory component for this table in the outline font resource directory.The font directory is described in "The Font Directory," beginning on page 4-70.
The control-value program, which uses these values, is contained in the preprogram table, which is described on page 4-85.
