DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a data processing system to which the code image conversion mechanism of the present invention is applied. The data processing system 1 includes a processing device 11, a main memory 12, a code image conversion mechanism 13, and an output device 1.
4 and an output device 15. The output device is an output device that can receive image format data (image data) and output the image format data.
There are a printer device, a facsimile device, an optical disk device, and the like. The number of output devices connected is not limited to this configuration example and is not particularly limited. Further, the main memory 12 may be one of the output devices to which the image format data is sent.

The code image conversion mechanism 13 comprises a processing device 131, a storage device 132, an image storage device 133, and an image data processing device 134. The processing device 131 controls the entire code image conversion mechanism and performs a conversion process from print data (code data) to image format data, as described later. The storage device 132 stores various fonts, CG font data of sizes, and output device condition information (including the case where the main memory 12 is used as the output device) written by the processing device 131 (dot density,
The font, size, presence or absence of processing such as compression, pitch between characters, pitch between lines, etc.), print data transferred from the processing device 11, etc. are stored. This storage device is a storage device such as a RAM or a disk, and these storage devices may be used in combination. The image storage device 133 stores the converted image format data. The image data processing device is a device that further processes the converted image format data such as compression, enlargement, reduction, rotation (rotation of the entire screen).

Next, the code image conversion process of the data processing system will be described with reference to the flowchart of FIG. Prior to the conversion, the processing device 131 stores the output device condition information regarding each output device in the storage device 132 of the code image conversion mechanism 13. It may be stored at any time before conversion. The processing device 11 transfers the output device designation information designating the output device to be output (including the case where the main memory 12 is used as the output device) to the code image conversion mechanism 13 and outputs the print data to be output to the main memory 12. From the read code image conversion mechanism 13. The transferred print data is stored in the storage device 132. The transfer method may be one code unit, a plurality of code units, or all code transfers. Next, the processing device 131 reads out the output device condition information regarding the output device specified by the output device specifying information from the storage device 132, and uses the CG font data, the character pitch, and the line spacing to be used according to the output device condition information regarding the read output device. Determine the pitch, etc., and whether or not processing such as compression and expansion is performed.

Based on this determination, the processing device 131 performs code image conversion on the print data for one page in the storage device 132 and stores it in the image storage device 133.
When the processing such as compression is designated, the processing device 131 causes the image data processing device to process the image format data stored in the image storage device 133, and stores the processing result in the image storage device 133 again. To do. When the processing for the print data for one page is completed and there is print data to be processed, the above processing is repeated. When the processing of all pages is completed, the processing device 131 reports the conversion completion to the processing device 11. Then, the processing device 11 instructs the processing device 131 to transfer the image format data based on the report.
The processing device 131 is a designated output device (main memory 1
2 includes an image storage device 133 as an output device)
The image format data stored in is transferred. Further, the processing device 11 does not give an instruction to transfer the image format data, and the processing device 1
31 may start the transfer of the image format data after reporting the conversion end to the processing device 11. Upon receiving the conversion completion report, the processing device 11 returns to the step of designating the output device and transferring the print data when there is another print data to be output, and ends the process when there is no print data.

In the process shown in the flow chart of FIG.
The image format data is transferred to the output device after all the print data conversion processes are completed. However, like the process shown in the flowchart of FIG. 3, the output device is executed every time the conversion process for one page of print data is completed. One page of image format data may be transferred. The other points are the same as the processing shown in the flowchart of FIG. Further, in the embodiment, the CG font data in the storage device 132 may be transferred and stored from the main memory 12 or an external storage device when necessary.
