Method Details

execute

public void execute(Stack<COSObject> operandStack,
 Map<ASAtom,COSObject> userDict)
             throws PostScriptException

Description copied from class: PSObject

Executes PostScript object. For literal objects this execution means pushing object to operand stack, for operator and procedure objects execution mean execution of this operator or procedure.

Specified by:

execute in class PSObject

Parameters:

operandStack - is stack for PostScript operands (see PostScript specification for further information).

userDict - is a dictionary that stores all key-value associated pair encountered during PostScript parsing. Full PostScript parser needs a dict stack, our implementation has only one dictionary.

Throws:

PostScriptException
