Raster and Vector Graphics

What is Raster and Vector Graphics?
Raster graphics come from Photoshop and Corel Photopaint and vector is produced by Adobe Illustrator, Free Hand, and CorelDraw. The results look similar but the way they are made is the difference. One uses more memory than the other.

Raster is made up of millions of squares,pixels of a variety of colors. The more pixels you have the better your image. The raster image can look smooth from a distance but when you zoom in the individual pixels show.

A vector is from a math formula for lines and curves. The quality of the image is the same no matter how close you zoom in. Vector files use millions of individual pixels but use less memory than the raster files
