A little experimentation should tell you whether the reassigning code can improve your graphics printouts.

Designing Your Own Graphics

This section takes you through the development of a graphics program. The example is not especially complicated, but it does include the same steps you would use for a more complex figure.

You should plan your figure with dots on graph paper, but before beginning to place the dots, you must decide which graphics density you want. Figure 6-2 shows the differences between three common modes so that you can choose the one you want.

In this figure you can see the main rules for graphic design in the three densities:

•In single-density no dots can be placed on vertical lines.

•In high-speed double-density, dots can be placed on vertical lines, but no dots can overlap.

•In double-density, dots can be placed on vertical lines, and they can overlap.

Figure 6-2.
