Designing bitmapped graphics

User interfaces and games can be made much more interesting using color graphics. The GLCD library includes a function called GLCD_DrawBitmap() that can be used to render 16-bit color bitmaps. Bitmaps can be designed using standard editors or downloaded from elsewhere. The following recipe shows you how to generate a simple bitmapped representation of a ball that can be used with the helloBounce and helloPong recipes we developed in Chapter 2, C Language Programming. We'll call this recipe bitmapBounce_c6v0.

How to do it…

To design bitmapped graphics, follow these instructions:

1. Create a color bitmap of width 16 pixels and height 24 pixels using the Windows Paint application. A screenshot of what this should look like ...
