Raster Graphics Commands

The graphics feature provides commands that enable you to design your own images in any shape you desire. These commands allow you to create and adjust the density of various lines and patterns in various combinations.

Note: The allowed ranges of n1 and n2 in the following commands are determined by the line length and limited by the width of the installed paper.

To find the values of n1 and n2 for any of the following commands, modify the procedure described for the Select 60 dpi Graphics command in Chapter 4. In step 1 of the procedure, substitute the appropriate dot density value for 60.
