Image drawing device, image drawing method, and image drawing program

An image drawing method in a device including a first processor that generates a plurality of pieces of second drawing data and a plurality of second drawing command groups including a plurality of second drawing commands from a plurality of pieces of first drawing data and a plurality of first drawing command groups including a plurality of first drawing commands and a second processor that executes a drawing process based on the plurality of pieces of second drawing data and the plurality of second drawing command groups outputted from the first processor, the method comprising:

• generating a plurality of third drawing command groups by changing an arrangement order indicating an order of executing the plurality of first drawing command groups and deleting first drawing commands that have become unnecessary to execute due to the changing of the arrangement order of the plurality of first drawing command groups among the plurality of first drawing commands;
• generating the plurality of pieces of second drawing data by combining pieces of first drawing data corresponding to third drawing commands that can be executed by the second processor in a same drawing condition among a plurality of third drawing commands included in the plurality of third drawing command groups, and generating the plurality of second drawing command groups corresponding to the plurality of pieces of second drawing data by deleting the third drawing commands that have become unnecessary due to the combining of the pieces of first drawing data;
• and
• executing each of the plurality of second drawing commands in an arrangement order of the plurality of second drawing commands.

An image drawing device comprising:

• first and second processors to execute a program;
• and
• a memory to store the program which, when executed by the first and second processors, performs
• a process of generating a plurality of pieces of second drawing data and a plurality of second drawing command groups including a plurality of second drawing commands from a plurality of pieces of first drawing data and a plurality of first drawing command groups including a plurality of first drawing commands;
• and
• a process of executing a drawing process based on the plurality of pieces of second drawing data and the plurality of second drawing command groups outputted from the first processor;
• wherein the program, when executed by the first processor, performs
• a process of generating a plurality of third drawing command groups by changing an arrangement order indicating an order of executing the plurality of first drawing command groups and deleting first drawing commands that have become unnecessary to execute due to the changing of the arrangement order of the plurality of first drawing command groups among the plurality of first drawing commands;
• a process of generating the plurality of pieces of second drawing data by combining pieces of first drawing data corresponding to third drawing commands that can be executed by the second processor in a same drawing condition among a plurality of third drawing commands included in the plurality of third drawing command groups and generating the plurality of second drawing command groups corresponding to the plurality of pieces of second drawing data by deleting the third drawing commands that have become unnecessary due to the combining of the pieces of first drawing data;
• and
• a process of executing each of the plurality of second drawing commands in an arrangement order of the plurality of second drawing commands.
