Types of Graphics

Graphics for computer systems are grouped into two different approaches that have different strengths and weaknesses. A raster graphic is an image composed of a two-dimensional pixel grid. Each pixel of a raster image has a color associated with it, and the mosaic of color creates a digital surrogate of an object. If you have ever taken a picture with a digital camera, you have created a raster image. A vector graphic, by contrast, uses sets of mathematical formulas to represent the different shapes in an image. One of the strengths that a vector-based graphic has over a raster-based graphic is the fact that you can resize a vector image with no loss in the quality of the image. Because vectors use mathematical formulas, resizing ...
