Print data processing system, print data processing method, and non-transitory computer readable medium

A print data processing method comprising:

• interpreting print data of a to-be-printed image written in a page description language and generating first intermediate format data, second intermediate format data, and attribute information, the first intermediate format data representing each image object of a predetermined type contained in the to-be-printed image, the second intermediate format data representing a portion of the to-be-printed image that is other than each image object of the predetermined type, and the attribute information being information about each image object of the predetermined type and indicating whether or not the image object and another image object overlap within the to-be-printed image;
• storing in a memory the first intermediate format data and first raster image data of each image object of the predetermined type, the first raster image data being generated by performing a drawing process on the first intermediate format data;
• and
• generating second raster image data to be supplied to a printer, by using the first intermediate format data and the first raster image data of each image object of the predetermined type that are stored in the memory and the second intermediate format data,
• wherein
• when the attribute information of each image object of the predetermined type indicates that the image object and another image object overlap within the to-be-printed image, the stored first intermediate format data of the image object is read out from the memory and is used in the generation of the second raster image data, and
• when the attribute information of each image object of the predetermined type indicates that the image object and another image object do not overlap, the stored first raster image data of the image object is read out from the memory and is used in the generation of the second raster image data.

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

• interpreting print data of a to-be-printed image written in a page description language and generating first intermediate format data, second intermediate format data, and attribute information, the first intermediate format data representing each image object of a predetermined type contained in the to-be-printed image, the second intermediate format data representing a portion of the to-be-printed image that is other than each image object of the predetermined type, and the attribute information being information about each image object of the predetermined type and indicating whether or not the image object and another image object overlap within the to-be-printed image;
• storing in a memory the first intermediate format data and first raster image data of each image object of the predetermined type, the first raster image data being generated by performing a drawing process on the first intermediate format data;
• and
• generating second raster image data to be supplied to a printer, by using the first intermediate format data and the first raster image data of each image object of the predetermined type that are stored in the memory and the second intermediate format data,
• wherein
• when the attribute information of each image object of the predetermined type indicates that the image object and another image object overlap within the to-be-printed image, the stored first intermediate format data of the image object is read out from the memory and is used in the generation of the second raster image data, and
• when the attribute information of each image object of the predetermined type indicates that the image object and another image object do not overlap, the stored first raster image data of the image object is read out from the memory and is used in the generation of the second raster image data.
