q. Color Conversion
In this block, a specific color of an original is converted into a different color. (For details, see the User's
Manual.)
When an area is selected on the editor, bit map data will be generated based on area data to determine
which pixels of the image should be corrected. In addition, if a registered color has been selected by a color
palette, color data will be read from the bit map memory to represent the selected pixels on the image.
