Information processing apparatus and image processing system for generating image data for a preview image by using print data described in page description language

A non-transitory computer-readable recording medium storing a program that causes a computer to execute a process performed in an information processing apparatus for generating image data for a preview image by using print data described in a page description language, the process comprising:

• acquiring the print data described in the page description language from outside of the information processing apparatus;
• extracting specific drawing information from the print data described in the page description language, and store the specific drawing information in a specific drawing information storage;
• the specific drawing information including multiple page description language commands necessary for generating a preview image of a specified page of the print data;
• accepting a request to display the image data of the specified page of the print data;
• reading, for each page in the print data up to a page before the specified page, specific drawing information corresponding to one page, from among the specific drawing information stored in the specific drawing information storage;
• and
• generating the image data of the specified page based on the read specific drawing information.

An image processing system for generating image data for a preview image by using print data described in a page description language, the image processing system comprising:

• a hardware processor;
• and
• a hardware memory containing instructions, which when executed, cause the hardware processor to:
• acquire the print data described in the page description language from outside of the information processing apparatus;
• extract specific drawing information from the print data described in the page description language, and store the specific drawing information in a specific drawing information storage;
• the specific drawing information including multiple page description language commands necessary for generating a preview image of a specified page of the print data;
• accept a request to display the image data of the specified page of the print data;
• read, for each page in the print data up to a page before the specified page, specific drawing information corresponding to one page, from among the specific drawing information stored in the specific drawing information storage;
• generate the image data of the specified page by applying based on the specific drawing information;
• and
• a second hardware processor;
• a hardware memory containing instructions, which when executed, cause the second hardware processor to:
• display the image data on a display device.
