8 What are bitmapped graphics? Bitmapped graphics, also known as raster graphics, consist of grids of tiny dots called pixels. Each pixel is assigned a color. Can be a continuous-tone image, such as a photograph Bitmap graphic editors are called paint programs Enlarging a bitmap graphic may cause the image to lose crispness and clarity

8 What are vector graphics? Vector graphics use mathematical formulas to define lines, curves,

8 What are vector graphics? Vector graphics use mathematical formulas to define lines, curves, and other attributes. Generally much smaller than raster graphic files Vector graphic editors are called draw programs Do not lose clarity as you enlarge them. Appear as bitmaps on computer monitors because computer monitors consist of pixels

8 Graphics Quality Two factors that determine graphics quality are resolution and color depth.

8 Graphics Quality Two factors that determine graphics quality are resolution and color depth. Resolution is the number of pixels per inch. Color depth refers to the number of distinct colors an image can contain. It can range from 2 -bit (black and white) to 24 -bit (16. 7 million colors).
