Abstract

A method and apparatus for processing resources in a hierarchically structured page description language. The resource must first be defined before it can be used. The definition of a resource is contained in a resource specification. The resource is defined by creating a linked list resource definition data structure which contains a reference to a resource specification and a reference to a subsequent resource definition data structure. Alternatively, the resource can be defined by downloading a predefined resource from non-volatile memory and reference is made to the downloaded resource specification in a AVAILABLE RESOURCE TABLE. It is also possible for default resources of the system to be found in the AVAILABLE RESOURCE TABLE. After a resource is defined, it must be declared. The declaration process uses a resource declaration data structure which has a reference to a defined resource specification and a reference to a subsequent resource declaration data structure.
