Abstract

Provided is an image forming device and a recording medium which can execute plural drawing processes in parallel without having to use different data lists for drawing processes. The image process device can include simultaneously plural drawing process sections each of which executes its rendering for lines one by one based on a display list. The image forming device causes the plural drawing process sections, each of which renders for a specific region that includes plural lines within a page, to render for different lines every specific number of lines, the specific number being determined by subtracting 1 from all the numbers of the plural drawing process sections that render their renderings for the specific regions.

First claim

What is claimed is:

1 . An image forming device comprising:
a processor that executes an image forming program; and a memory that stores the image forming program, the processor being capable of, pursuant to instructions of the image forming program, including plural drawing process sections that render for lines one by one based on a display list, the plural drawing process sections, each of which renders for a specific region that includes plural lines within a page, rendering for different lines every specific number of lines, the specific number being determined by subtracting 1 from all the number of the multiple drawing process sections that execute their renderings for the specific regions.

2 . The image forming device according to claim 1 , wherein
the processor acts, pursuant to instructions of the image forming program, as a parallel process number determination section that determines of the number of the drawing process sections to be provided simultaneously depending on a situation of the image forming device, and if the parallel process number determination section determines of the number of the drawing process sections to be provided simultaneously which execute their renderings for a specific region within a page in which plural lines are included, the plural drawing process, each of which renders for a specific region within a page, render for different lines one by one by skipping every specific number of lines, the specific number being determined by subtracting 1 from all the number of the plural drawing process sections that execute their renderings for the specific regions.

3 . The image forming device according to claim 2 , wherein if the parallel process number determination section determines to provide plural drawing processes in the image forming device each of which renders a specific region that includes plural lines within a page and concurrently if plural objects are included in the specific region, pursuant to the instructions of the image forming program, the processor operates to render for the plural objects in a sequential manner based on lines counted with reference to the specific region.

4 . The image forming device according to claim 2 , wherein the parallel process number determining section determines to provide the plural drawing process sections that execute their renderings for different regions among plural regions obtained by dividing a page.

5 . The image forming device according to claim 4 , wherein the plural regions have the same area, and the parallel process number determination section determines of the number of the plural drawing process sections to be provided simultaneously which execute their renderings for different regions by predicting an equalization of rendering process times for the plural regions.

6 . The image forming device according to claim 1 , wherein if plural objects are included in a specific region, pursuant to the instructions of the image forming program, the processor causes the drawing process section that executes its rendering for a specific region to render for the plural objects one by one in a sequential manner based on lines counted with reference to the specific region.

7 . The image forming device according to claim 1 , wherein pursuant to the instructions of the image forming program, the processor includes plural drawing process sections simultaneously that execute their renderings for different regions among plural regions obtained by dividing a page.

8 . A recording medium in the form of a non-transitory computer-readable recording medium that stores an image forming program executable by a computer,
the image forming program causing the computer, based on a display list, to realize simultaneously plural drawing process sections each of which executes its rendering for lines one by one, and causing the plural drawing process sections, each of which execute its rendering for a specific region that includes plural lines within a page, to render for different lines every specific number of lines, the specific number being determined by subtracting 1 from all the number of the plural drawing process sections that render their renderings for the specific regions.

9 . The recording medium according to claim 8 , wherein the image forming program causes the computer to realize a parallel process number determination section that determines of the number of the plural drawing process sections to be provided depending on a situation of the computer, and if the parallel process number determination section determines simultaneously of the plural drawing process sections to be provided each of which renders for a specific region that includes plural lines within a page, each of the drawing process sections executes its rendering for different lines every specific number of lines, the specific number being determined by subtracting 1 from all the numbers of the plural drawing process sections that execute their renderings for the specific regions.
