Description

  The present invention relates to a conversion control device that controls conversion from page description data representing an image for each page to raster image data that can be output by an output device, and a conversion control program that causes a computer to operate as such a conversion control device. About.

  Conventionally, in the field of printing, DTP (Desk Top Publishing) that performs editing work using a computer has been widely applied. DTP realizes the philosophy of WYSIWYG (What You See Is What You Get). The operator edits characters and images while looking at the display screen and confirms the image of the printed matter. After that, images and the like can be printed and made with a printer or an image setter.

In this DTP, application software used when an operator edits characters and images is generally called DTP application software. Based on elements such as characters and images edited by the operator, page description data representing an image for each page is generated by the DTP application software. This page description data is vector data that does not depend on the resolution of the output device such as a printer or an image setter, and cannot be output by the output device as it is. Therefore, the page description data is rasterized by RIP (Raster Image Processor). By doing so, elements such as characters and images that make up the page are converted into raster image data represented as a set of dots, and output devices such as printers, platesetters, and filmsetters can output data based on this raster image data. An image is output (for example, refer nonpatent literature 1).

  Here, the RIP described above is provided with a memory in order to shorten the calculation time for the vector data analysis executed in the rasterizing process in the RIP, and this memory includes characters and images constituting the page. A capacity is allocated to each type of element classified into a plurality of types, and the allocation of the allocation is determined by predetermined parameters. However, depending on the configuration content of the page represented by the page description data input to the RIP, such memory allocation may cause inefficiency of rasterization processing in the RIP.
