Lesson 8. Importing and Linking Graphics > Comparing vector and bitmap graphics

Comparing vector and bitmap graphics

The drawing tools of Adobe InDesign and Adobe Illustrator create vector graphics, which are made up of shapes based on mathematical expressions. Vector graphics consist of smooth lines that retain their clarity when scaled. They are appropriate for illustrations, type, and graphics, such as logos that are typically scaled to different sizes.

Bitmap images are based on a grid of pixels and are created by image-editing applications, such as Adobe Photoshop. In working with bitmap images, you edit individual pixels rather than objects or shapes. Because bitmap graphics can represent subtle gradations of shade and color, they are appropriate for continuous-tone images, such as photographs or artwork created in painting programs. A disadvantage of bitmap graphics is that they lose definition and appear “jagged” when enlarged. Additionally, bitmap images are typically larger in file size than a similar vector file.
