What is the difference between a raster and a vector image?
Raster images are made up of individual pixels, and the size of the image is constrained by the number of pixels present in the file. For example, think of a digital photograph. You can usually enlarge a photo from your personal digital camera to about 8×10 without any distortion or blurring of the image, but if you try to make a large poster with the photo, it may start to look blurry and effect the quality of the image. Vector images are made up of a series of points connected by straight or curved lines. These points and lines are associated to each other both geometrically and mathematically allowing the image to be resized over and over again with no change in image quality.
