Abstract
A system and methods for comparing graphic elements in a changed document to those in a reference document is described. Attributes of selected graphic elements are first adjusted before comparing so that comparing does not identify certain document changes.
Claims22
A method for page-wise comparing a first document and a second document, each including at least one page, wherein a pair of pages to be compared, one from each of the first document and the second document, respectively comprise corresponding first and second pluralities of graphic elements, the method comprising the steps of:
- compensating for a change made in producing the second document that would cause one of the second plurality of graphic elements to be identified as a changed element in a comparison of the first and second documents, wherein identifying the changed element would produce an undesirable result;
- comparing the first plurality of graphic elements and the second plurality of graphic elements;
- and
- generating information describing results of the comparing step.
A computer-accessible memory system storing computer code for implementing a method for page-wise comparing a first document and a second document, each including at least one page, wherein a pair of pages, one from each of the first document and second document, to be compared respectively, comprise corresponding first and second pluralities of graphic elements respectively, and wherein the computer code comprises:
- code for compensating for a change made in producing the second document that would cause one of the second plurality of graphic elements to be identified as a changed element in a comparison of the first and second documents, wherein identifying the changed element would produce an undesirable result;
- code for comparing the first plurality of graphic elements and the second plurality of graphic elements;
- and
- code for generating information describing results of the comparing.
