“Marks” are graphics comprising 16 by 16 dots that can be used as characters.
They can be used as custom characters within character strings.
“Image data” are graphics comprising any required area of dots. They are regis-
tered in advance and as many as required can be displayed at any position on
the screen.
Windows bit map (BMP) data can be used for images.
There is a two-color mode, in which the display color and background color of the
image are specified when it is registered in a screen, and an eight-color mode in
which colors are assigned to the image in advance.
Since image data is composed of dots, it requires a large data size but offers
great powers of expression.
