Vector VS Raster Graphics

Vector graphics define each and every element in the image through mathematical code (postscript). They are composed of geometric and color information. Vector Graphics are resolution-independent (ADVANTAGE). This means that the image quality will remain consistent no matter how large or small the figure is sized. Popular examples of vector programs: Adobe Illustrator Macromedia Freehand, Corel Draw, PowerPoint, Deneba Canvas

These graphics are considered object oriented because everything you make, even text, is an object that can be manipulated independent of other objects and the background. 

NOTE: Vector Graphics will give the highest quality results throughout the publication process. 

Raster graphics are composed of pixels. This format is most commonly used for photographic images. Raster graphics are resolution-dependent (DISADVANTAGE), since resolution has an effect on the total number of pixels that are available within an image. The dimensions of these images cannot be increased without degrading the quality of the image. Popular examples of raster programs: Adobe Photoshop, Corel Photo Paint 

Combination files combine the benefits of both file types, while avoiding their limitations.  They can contain photographic elements, line art, text and complex formatting and positioning.
