Patent ID: 7589847

Claim:
A method of a document processing system comprising: identifying at least one image in a PDF file; prioritizing the identified image with respect to an aspect of the identified image; comparing the aspect of the identified image to a threshold of criteria; converting the PDF file into a postscript data stream; locating a first encounter of the identified image in the postscript data stream; associating a reference with the first encountered image in a postscript data stream main file; creating a memory for each first encountered image including information necessary for recreating such image; locating a reoccurrence of the identified image in the postscript data stream; segregating the recurring image from the postscript data stream if the threshold of criteria is not met; storing the segregated image separately from a remainder of the postscript data stream; and inserting the associated reference into the postscript data stream in place of the separately stored image.
