Design Your Own Graphics

In this section we take 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 so that you have the basis for designing graphics on your LX-80.

You will plan your figure with dots on graph paper, but before beginning to place the dots, you should decide which graphics density you want. Figure 9-3 shows the differences between the three most- used graphics modes so that you can choose the one you want.

Figure 9-3. Designing in different densities

In this figure you can see the main rules for graphics 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 low-speed double density dots can be placed on vertical lines and they can overlap.

Now look at our figure designed for high-speed double density. It should point you in the right direction for your own designs.
