SELECTION OF AFP OBJECTS IN PRINT DATA BY USE OF STACKS

摘要

Systems and methods are provided for utilizing stacks to identify Advanced Function Presentation (AFP) objects. The system includes a memory and a controller. The memory is able to store AFP print data. The controller is able to perform a parsing process on the AFP print data to identify AFP objects. During the parsing process the controller is able to: (A) advance a parsing location within the AFP print data, and (B) if the parsing location corresponds with a BEGIN field for an AFP object, then push an entry representing the AFP object onto a stack. During the parsing process, the controller is further able to (C) determine whether the stack matches a pattern of entries defined by a rule, (D) if the stack matches the pattern, then process the AFP object at the parsing location to perform an action defined in the rule, and (E) repeat operations (A)-(D).

1. A system comprising:
a memory configured to store AFP print data; and a controller configured to perform a parsing process on the AFP print data to identify AFP objects, wherein during the parsing process the controller is configured to:
(A) advance a parsing location within the AFP print data;(B) if the parsing location corresponds with a BEGIN field for an AFP object, then push an entry representing the AFP object onto a stack;(C) determine whether the stack matches a pattern of entries defined by a rule;(D) if the stack matches the pattern, then process the AFP object at the parsing location to perform an action defined in the rule;(E) repeat operations (A)-(D).
