• step S323 the image information request process can be skipped.
• the rotated image and the non-rotated image are allocated to each of the even-numbered and odd-numbered object handles.
• the present invention is not limited to this allocation rule. example
• (rotated image + X) may be assigned as a non-rotated image (X is an arbitrary integer), or a specific bit of the object number or middle point may be used to specify rotation or non-rotation of the image.
• any method can be used as long as it can correlate the rotated and Z or resized image with the corresponding original image.
• the DSC3012 it is not always necessary to share the assignment rule described above based on the premise that the assignment rule is mutually shared to recognize whether or not the device is a force. It is only necessary for the DSC3012 to recognize that the PDC 1000 is an “allocation rule compatible device” from the PD printer 1000. The DSC3012 operates according to the above allocation rules without knowing whether the connected PD printer 1000 is a “connection rule compatible device”. Just do it. This is because the PD printer 1000 corresponding to the allocation rule requests image data using an even number of object handles as necessary. If the PD printer 1000 does not support allocation rules, image data is always requested using an odd number of object handles.
• the object of the present invention is to provide a system or device with a storage medium storing software program codes for realizing the functions of the present embodiment, and to the computer of the system or device (or CPU or MPU). ) Power It can be achieved even if the program code is read and executed.
• the read program code itself realizes the functions of the above-described embodiment, and the storage medium storing the program code constitutes the present invention.
• Examples of storage media for supplying such program codes include floppy (registered trademark) disk, hard disk, optical disk, magneto-optical disk, CD-ROM, CD-R, magnetic tape, and non-volatile memory power. And ROM can be used.
• the program code whose storage medium power is also read is inserted into the computer. After writing to the memory of the function expansion board or function expansion unit connected to the computer, based on the instructions of the program code, the CPU of the function expansion board or function expansion unit will perform the actual processing. This includes the case where the functions of the above-described embodiment are realized by performing part or all of the processing.
