Image processing apparatus, image output device, image processing method and record medium on which image processing program is recorded

An image processing method for expanding code image data to plotted pattern data, comprising:

• a selection process for selecting whether the code image data is expanded to binarized plotted pattern data or multivalued plotted pattern data;
• an expansion process for expanding the code image data to plotted pattern data selected in the selection process;
• and
• a synthesis process for synthesizing plotted pattern data expanded in the expansion process.

A record medium on which an image processing program for instructing a computer to expand code image data to plotted pattern data is recorded, wherein

• the image processing program instructs a computer to select whether the code image data is expanded to binarized plotted pattern data or to multivalued plotted pattern data;
• the image processing program instructs said computer to expand the code image data to the selected plotted pattern data;
• and
• the image processing program instructs said computer to synthesize the expanded plotted pattern data.
