4.1.1. bitmaps is a data matrix that describe the characteristics of all the pixels making up an image

4.2. capturing and editing images

4.3. vector editors-drawing program

4.4. users can scan images from conventional sources and make necessary alterations and manipulations

5. Bitmaps sources

5.1. where do bitmaps come from?

5.1.1. capture a bitmap using a camera from a photo

5.1.2. grab from an active computer screen
