A computer implemented method to modify an intermediate representation of graphics data written in a page description language is described. The method renders the graphics data to produce a print preview representation stored as intermediate graphics data in an intermediate graphics format. A modifying operation for modifying graphics content of the print preview representation is detected, and the method determines whether the print preview representation contains information about the graphics data required to perform the modifying operation based on a class of the modifying operation and a content of the print preview representation affected by the detected modifying operation. Where the print preview representation contains information required to perform the modifying operation, the print preview representation is modified, and otherwise the method utilises the graphics data written in the page description language to apply the modifying operation. An apparatus, storage medium and printer using the method(s) are also discussed.
A method for modifying an intermediate representation of graphics data written in a page description language, the method comprising:
A non-transitory computer readable storage medium having a program recorded thereon, the program being executable by a processor to modify an intermediate representation of graphics data written in a page description language, the program comprising:
A computer apparatus comprising at least one processor and a memory storing a program, the program being executable by the processor to modify an intermediate representation of graphics data written in a page description language, the program comprising:
