PURPOSE:To easily execute picture drawing even in the case of a graphic having a part protruded beyond a frame by processing automatically a device depending graphic drawing instruction train so as to be held in the frame, when the device depending graphic drawing instruction train which has converted a device independing graphic drawing instruction train exceeds a frame of a graphic drawing range of a device depending coordinate system. CONSTITUTION:A graphic data conversion processing means 30 derives the maximum value and the minimum value of a device depending coordinate value which is transformed. A device depending coordinate correction value generating means 40 decides whether the movement is necessary or not, based on a device depending coordinate system can be maximum value and the minimum value of the device depending coordinate value which is transferred, and calculates a correction value of the device depending coordinate value for the moment when it is necessary. The graphic data conversion processing means 30 corrects a device depending graphic drawing instruction train which is converted, based on this correction value and outputs it to a graphic output device 50. In such a way, a program can be generated without being aware of a frame of a graphic drawing range, and even in the case of graphic having a part which has protruded beyond the frame, picture drawing can be executed without causing the increase of the processing time and the program generation scale. |
