ABSTRACT
When computer graphics are created, they are either raster or vector images. Photoshop supports both types of images, and it is common to mix the two in a single project. Newer versions of Photoshop contain the vector type, giving it the ability to be resized and edited within Photoshop and After Effects. While all graphics for video end up as raster images, a clear understanding of the two categories will help reader build, modify, and import artwork. Vector graphics are often used for corporate logos and print pieces. Vector graphics are resolution-independent because they are composed of lines and curves defined by mathematical objects called vectors. Vectors describe an image by its geometric characteristics or shapes. The requirements of print differ greatly from those for video. It is necessary to work with a much higher quantity of pixels to produce satisfactory results when outputting to the printed page.
