Information processing apparatus, information processing method, and computer readable medium

An image processing method comprising:

• receiving print information described in a page description language, wherein the received print information includes a page data and an overlay data, and the page data includes a command to call an overlay;
• performing a rasterization process of converting the print information into bitmap data;
• saving the bitmap data, which has been generated using the rasterization process, as cache data for each of objects included in the print information;
• detecting, among the objects included in the print information, an object that is identified as being printed only once to obtain a detection result;
• converting, in accordance with the detection result, the identified object as being printed only once for the print information into page data, and converting the page data by removing a command to call an overlay performing only once in the page data and adding the overlay data corresponding to the command to call the overlay at a place where the command to call the overlay has existed;
• storing the page data;
• and
• removing in accordance with a result of the detection only bitmap data saved as cache data, for the object which is identified as being printed only once for the print information.

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

• receiving print information described in a page description language, wherein the received print information includes a page data and an overlay data, and the page data includes a command to call an overlay;
• performing a rasterization process of converting the print information into bitmap data;
• saving the bitmap data, which has been generated using the rasterization process, as cache data for each of objects included in the print information;
• detecting, among the objects included in the print information, an object that is identified as being printed only once to obtain a detection result;
• converting, in accordance with the detection result, the identified object as being printed only once for the print information into page data, and converting the page data by removing a command to call an overlay performing only once in the page data and adding the overlay data corresponding to the command to call the overlay at a place where the command to call the overlay has existed;
• storing the page data;
• and
• removing in accordance with a result of the detection only bitmap data saved as cache data, for the object which is identified as being printed only once for the print information.
