Furthermore, those kinds of graphics offer smaller file sizes then bitmaps, because they don't store file for each pixels. The drawbacks for the drawing-type graphics are that if the screen consists of a lot of objects, it will take more time to display. On the other hand, Drawing-type graphics can't give dedicated photo effect. So for simple illustrations, drawing-type graphics are the ideal choice, but for the fantasy picture the bitmaps are the best one. As shown in Figure 2-4.
Bitmaps are the graphics that compose of dots, or called pixels arranged in rows and columns.
The more bits that represent each pixel, the more shades of color you can see. It can represent 16 colors or gray levels. It can represent 256 colors. It can represent 16 million colors. You can create bitmaps by a. drawing them in a paint program.
