Image conversion apparatus, and image conversion program storage medium
According to an image conversion apparatus of the present invention, there is created the third image data (PostScript) file having the second layout having a page in which plural image objects are collected and arranged together, so that the plural image objects are rasterized once. This feature makes it possible to reduce the overheads at the time of the rasterizing and thereby improving the productivity of images as a system.
1 . An image conversion apparatus that converts first image data representative of printing images over a plurality of pages, wherein the first image data consists of a plurality of image objects, and a definition of a layout of the plurality of image objects, into second image data which is rasterized and divided into pages, the image conversion apparatus comprising:
a first object arrangement section that creates third image data having a second layout having a page in which a plurality of image objects is arranged, the second layout being different from the layout of the image objects on the printing images, in accordance with the first image data;
a rasterizing processing section that creates fourth image data by rasterizing the third image data; and
a second object arrangement section that derives image objects after the rasterizing from the fourth image data and constructs the second image data in such a manner that the derived image objects arranged to meet a layout for each page of the printing images.
2 . An image conversion apparatus according to claim 1 , wherein the first object arrangement section further creates object information representative of arrangement positions of the plurality of image objects on the second layout, and layout information representative of arrangement positions of the plurality of image objects on the printing image, and
the second object arrangement section derives image objects after the rasterizing in accordance with the object information, and arranges the derived image objects in accordance with the layout information.
3 . An image conversion apparatus according to claim 1 , wherein the plurality of image objects comprises reusable objects that are used a plurality of number of times, and non-reusable objects that are used by only once, and the first image data is image data representative of a variable printing image over a plurality of pages, and
the first object arrangement section creates the third image data having the second layout, in which with respect to the reusable objects, one reusable object is arranged into a page, and with respect to the non-reusable objects, non-reusable objects included in every page of the variable printing image are collected together and arranged into one page.
4 . An image conversion program storage medium storing an image conversion program, which causes an information processing apparatus to operate as an image conversion apparatus that converts first image data representative of printing images over a plurality of pages, wherein the first image data consists of a plurality of image objects, and a definition of a layout of the plurality of image objects, into second image data which is rasterized and divided into pages, the image conversion apparatus comprising:
a first object arrangement section that creates third image data having a second layout having a page in which a plurality of image objects is arranged, the second layout being different from the layout of the image objects on the printing images, in accordance with the first image data;
a rasterizing processing section that creates fourth image data by rasterizing the third image data; and
a second object arrangement section that derives image objects after the rasterizing from the fourth image data and constructs the second image data in such a manner that the derived image objects arranged to meet a layout for each page of the printing images.
5 . An image conversion program storage medium storing an image conversion program according to claim 4 , wherein the first object arrangement section further creates object information representative of arrangement positions of the plurality of image objects on the second layout, and layout information representative of arrangement positions of the plurality of image objects on the printing image, and
the second object arrangement section derives image objects after the rasterizing in accordance with the object information, and arranges the derived image objects in accordance with the layout information.
6 . An image conversion program storage medium storing an image conversion program according to claim 4 , wherein the plurality of image objects comprises reusable objects that are used a plurality of number of times, and non-reusable objects that are used by only once, and the first image data is image data representative of a variable printing image over a plurality of pages, and
the first object arrangement section creates the third image data having the second layout, in which with respect to the reusable objects, one reusable object is arranged into a page, and with respect to the non-reusable objects, non-reusable objects included in every page of the variable printing image are collected together and arranged into one page.
