Claims
- 1. A method of image processing, comprising:(a) providing in a memory: (i) data of a page being composed for imaging, and (ii) data of at least one composed page waiting to be imaged; (b) detecting indicia indicative of a memory management task performed on data of the at least one composed page waiting to be imaged to reduce storage inefficiencies in the memory while the at least one composed page is waiting to be imaged; and, (c) in response to detecting the indicia, manipulating in the memory the data of the page being composed to reduce storage inefficiencies in the memory.
- 2. The method of claim 1 wherein the memory is associated with an imaging device including a printer, copier, or facsimile device.
- 3. The method of claim 1 wherein the data of the at least one composed page in the memory on which the memory management task is performed includes a raster patch, font, pattern, video band, monster band or vector band.
- 4. The method of claim 1 wherein the memory management task performed on the data of the at least one composed page waiting to be imaged is performed by using an atomic operation for collision avoidance with a video imaging task.
- 5. The method of claim 1 wherein the memory management task performed on the data of the at least one composed page waiting to be imaged is performed by using a critical section locking mechanism for collision avoidance with a video imaging task.
- 6. The method of claim 1 wherein the memory management task includes compressing the data.
- 7. The method of claim 1 wherein the memory management task includes relocating the data.
- 8. The method of claim 1 wherein the memory management task includes compressing and relocating the data.
- 9. The method of claim 8 further including compressing and relocating the data using a memory fragmentation avoidance technique.
- 10. The method of claim 1 further including, in response to detecting the indicia, performing a memory management task on data of at least a next page being composed.
- 11. The method of claim 10 further including, in response to not detecting any further indicia and in response to detecting a threshold being met, discontinuing the performing of the memory management task on data of one of the at least a next page being composed.
- 12. The method of claim 1 wherein the memory management task is performed on data of the page being composed without waiting for any composed page to finish imaging.
- 13. A computer-readable medium having computer-executable instructions for performing steps including:(a) providing in a memory: (i) data of a page being composed for imaging, and (ii) data of at least one composed page waiting to be imaged; (b) detecting indicia indicative of a memory management task performed on data of the at least one composed page waiting to be imaged to reduce storage inefficiencies in the memory while the at least one composed page is waiting to be imaged; and, (c) in response to detecting the indicia, manipulating in the memory the data of the page being composed to reduce storage inefficiencies in the memory.
- 14. An image processing apparatus, comprising:(a) an imaging engine operatively connected to a memory, the memory including: (i) data of a page being composed for imaging, and (ii) data of at least one composed page waiting to be imaged; (b) means for detecting indicia indicative of a memory management task performed on data of the at least one composed page waiting to be imaged to reduce storage inefficiencies in the memory while the at least one composed page is waiting to be imaged; and, (c) means for manipulating in the memory the data of the page being composed for imaging to reduce storage inefficiencies in the memory in response to detecting the indicia.
- 15. The apparatus of claim 14 wherein the memory is associated with an imaging device including a printer, copier, or facsimile device.
- 16. The apparatus of claim 14 wherein the data of the at least one composed page in the memory on which the memory management task is performed includes a raster patch, font, pattern, video band, monster band or vector band.
- 17. The apparatus of claim 14 further including means for performing the memory management task on the data of the at least one composed page waiting to be imaged, including means for enabling an atomic operation for collision avoidance with a video imaging task.
- 18. The apparatus of claim 14 further including means for performing the memory management task on the data of the at least one composed page waiting to be imaged, including a critical section locking mechanism for collision avoidance with a video imaging task.
- 19. The apparatus of claim 14 wherein the memory management task includes compressing the data.
- 20. The apparatus of claim 14 wherein the memory management task includes relocating the data.
- 21. The apparatus of claim 14 wherein the memory management task includes compressing and relocating the data.
- 22. The apparatus of claim 21 wherein the memory management task further includes compressing and relocating the data using a memory fragmentation avoidance technique.
- 23. The apparatus of claim 14 further including means for performing a memory management task on data of at least a next page being composed without waiting for any composed page to finish imaging.
- 24. The apparatus of claim 14 wherein the means for performing a memory management task on the data of the page being composed includes means for performing the memory management task without waiting for any composed page to finish imaging.
- 25. A method comprising:(a) storing in a memory first data of at least one composed page waiting to be imaged; (b) storing in the memory second data of at least one page to be composed for imaging; (c) initiating composing of the second data; (d) detecting indicia indicative of a manipulation of the first data in the memory to conserve the memory; and, (e) in response to detecting the indicia, manipulating the second data in the memory to conserve the memory and enable a continued composing of the second data.
- 26. An imaging device, comprising:(a) a print engine coupled to a memory, the memory having stored therein (i) data of at least a first composed page waiting to be imaged, and (ii) data of at least a second page not completely composed; and, (b) first control logic configured to compose the second page; (c) second control logic configured to detect indicia indicative of a manipulation of the first data in the memory to conserve the memory; (d) third control logic enabled, in response to detecting the indicia, to manipulate the second data in the memory to conserve the memory and enable a continued composing of the second data.
- 27. A computer-readable medium having computer-executable instructions for enabling steps including:(a) storing in a memory first data of at least one composed page waiting to be imaged; (b) storing in the memory second data of at least one page to be composed for imaging; (c) initiating composing of the second data; (d) detecting indicia indicative of a manipulation of the first data in the memory to conserve the memory; and (e) in response to detecting the indicia, manipulating the second data in the memory to conserve the memory and enable a continued composing of the second data.
