Difference Between Vector and Raster image There are two kinds of computer graphics - raster (composed of pixels) and vector (composed of paths). Raster images are more commonly called bitmap images. A bitmap image uses a grid of individual pixels where each pixel can be a different color or shade. Bitmaps are composed of pixels. Vector graphics use mathematical relationships between points and the paths connecting them to describe an image. Vector graphics are composed of paths. The image to the left below is representative of a bitmap and the image to the right is representative of a vector graphic. They are shown at four times actual size to exaggerate the fact that the edges of a bitmap become jagged as it is scaled up: Bitmap Image: Vector Graphic: With Adobe® Systems' introduction of the PostScript® page-description language computers could display fonts and images using point-to-point math rather than by pixels alone. The advantage to using a page-descript
