Abstract

Aspects of the present invention are related to systems and methods for rendering graphical objects in a printing system. According to one aspect of the present invention a graphic list may be partitioned, and the graphic-list partitions may be rendered “out-of-order” or concurrently.

Claims

1. A method, in a printing system, for rendering a print job, said method comprising:

receiving, associated with a print job, a graphic list comprising a first graphic-list element, an immediately previous graphic-list element and an immediately subsequent graphic-list element;

assigning said first graphic-list element to a first partition, wherein said first partition is a partition associated with said immediately previous graphic-list element when a first graphical-object type associated with said first graphic-list element is the same as a third graphical-object type associated with said immediately previous graphic-list element and said first partition is a newly created partition, not associated with said immediately previous graphic-list element, when said first graphical-object type is not the same as said third graphical-object type;

comparing said first graphical-object type with a second graphical-object type associated with said immediately subsequent graphic-list element;

when said first graphical-object type and said second graphical-object type are the same, assigning said immediately subsequent graphic-list element to said first partition; and

when said first graphical-object type and said second graphical-object type are not the same, creating a second partition and assigning said immediately subsequent graphic-list element to said second partition.

2. The method as described in claim 1, wherein said first graphical-object type is a type selected from the group consisting of text graphical object, vector graphical object and pictorial graphical object.

3. The method as described in claim 1 further comprising associating said first graphical-object type with said first partition.

4. The method as described in claim 1 further comprising associating said first partition with a first renderer, wherein said first renderer is a first specialized renderer associated with said first graphical-object type.

5. The method as described in claim 4, wherein said first graphical-object type is a type selected from the group consisting of text graphical object, vector graphical object and pictorial graphical object.

6. The method as described in claim 4 further comprising associating said second partition with a second renderer, wherein said second renderer is a second specialized renderer associated with said second graphical-object type.

7. The method as described in claim 6 further comprising:

rendering said first partition on said first specialized renderer; and

rendering said second partition on said second specialized renderer.

8. The method as described in claim 7, wherein said rendering said first partition and said rendering said second partition occur substantially concurrently.

9. The method as described in claim 1 further comprising associating a first partition order with said first partition.

10. The method as described in claim 9 further comprising associating a second partition order with said second partition, wherein said first partition order and said second partition order indicate that said first partition be bit-blit prior to said second partition.
