SingleOpSummary

Single-Operator Functions

The single-operator functions listed here begin with the prefix "PS." For every single-operator function with a "PS" prefix, there's a corresponding single-operator function with a "DPS" prefix. The PS and DPS functions are identical except that DPS functions take an additional (first) argument that represents the PostScript execution context. To conserve space, only the single-operator functions prefixed with "PS" are listed here. (See "Suggested Reading" for references to documentation about Display PostScript.)
Besides using the standard C types, these single-operator functions use boolean and userobject. A boolean variable is an int having either a zero or a nonzero value. The zero value is equivalent to the PostScript value false, and the nonzero value is equivalent to the PostScript value true. The userobject type is an int that refers to the value returned by DPSDefineUserObject().
