Computer graphics fall into two main categories, bitmap graphics and vector graphics. Adobe Illustrator is a vector based software package. Drawing programs such as Illustrator create vector graphics made of lines and curves, defined by mathematical objects called vectors. A vector graphic is resolution-independent! What this means for you is that unlike pixel based images, a vector based piece of artwork can be scaled to any size and printed on any output device (printer) at any resolution without losing its detail or clarity. Vector graphics are the best choice for type, and bold graphics that need to maintain their crispness at various scales.
In Adobe Illustrator you "draw" objects. Objects are simply the points, lines, shapes and paths that you create on the page.
What makes Illustrator powerful is its ability to manipulate any object as a graphic element.
You will learn about creating and manipulating bitmap or raster images in the Photoshop portion of the class.
