Image forming apparatus, method for controlling same, and storage medium

A method for controlling an imaging apparatus, comprising:

• inputting print data;
• interpreting the input print data;
• determining whether or not a rendering command targeted for reusable data included in the print data depends on a placement location for placement of the rendering result in a physical coordinate space based on the interpretation result of the print data;
• generating cache data corresponding to the reusable data based on the interpretation result of the print data without graphic processing for the rendering command targeted for the reusable data and storing the generated cache data in a storage unit when it is determined that the rendering command depends on a placement location for placement of the rendering result in a physical coordinate space or performing graphic processing for the rendering command targeted for the reusable data, generating cache data corresponding to the reusable data based on the result of the graphic processing, and storing the generated cache data in a storage unit when it is determined that the rendering command does not depend on a placement location for placement of the rendering result in a physical coordinate space;
• determining whether or not a command to be executed, which is included in the print data, is a command for reusing reusable data;
• determining whether or not cache data corresponding to the reusable data stored in the storage unit needs to be subjected to graphic processing when the command to be executed is determined that the command for reusing reusable data;
• and
• generating rendering data based on the cache data when determined that the cache data does not need to be subjected to graphic processing or generating rendering data after executing the graphic processing for the cache data when determined that the cache data needs to be subjected to graphic processing.

A non-transitory storage medium on which is stored a computer program for making a computer execute:

• inputting print data;
• interpreting the input print data;
• determining whether or not a rendering command targeted for reusable data included in the print data depends on a placement location for placement of the rendering result in a physical coordinate space based on the interpretation result of the print data;
• generating cache data corresponding to the reusable data based on the interpretation result of the print data without graphic processing for the rendering command targeted for the reusable data and storing the generated cache data in a storage unit when it is determined that the rendering command depends on a placement location for placement of the rendering result in a physical coordinate space or performing graphic processing for the rendering command targeted for the reusable data, generating cache data corresponding to the reusable data based on the result of the graphic processing, and storing the generated cache data in a storage unit when it is determined that the rendering command does not depend on a placement location for placement of the rendering result in a physical coordinate space;
• determining whether or not a command to be executed, which is included in the print data, is a command for reusing reusable data;
• determining whether or not cache data corresponding to the reusable data stored in the storage unit needs to be subjected to graphic processing when the command to be executed is determined that the command for reusing reusable data;
• and
• generating rendering data based on the cache data when determined that the cache data does not need to be subjected to graphic processing or generating rendering data after executing the graphic processing for the cache data when determined that the cache data needs to be subjected to graphic processing.
