Raster images display finer gradation in light and shading at the right resolution.Īnother disadvantage of vector images is that they cannot be used in an electronic format they must first be converted to a raster image. Raster images are used for photographs and high colored images in web and print, as they are capable of displaying various different colors in a single image and allow for color editing in the image. Hence, the logo will look the same on a business card as it will on a billboard. Vector images are often used for logos, letterheads, texts, and other designs, as it always the image to be resized without effecting its quality. A raster image, on the other hand, is visibly pixilated when enhanced. This is mainly due to the mathematical formulas, which allow the image to hold its form, as the formula dictates how the image is rendered. The advantage that vector images have over raster images is that vector images can be resized without any visible negative impacts. A vector image is limited, as an image has to be looped and closed off before it can be filled with color. Raster images are mainly used for high density images, or images with many different colors, as each pixel can have a different color, which can be overlapped for different colors and shapes. The data file for a vector image contains the points where the paths start and end, how much the paths curve, and the colors that either border or fill the paths. A vector image is made up of paths, each with a mathematical formula, also known as a vector, which tells the path how the each part of the image is shaped and what color it is bordered with or filled by. Examples of raster images include gif or jpeg. Raster images are more commonly called bitmap images. Vector images are typically generated using drawing or illustration programs, such as Adobe Illustrator.Ī raster images uses different colored pixels, which are arranged in a manner to display an image. Raster images are produced by digital image capture devices, such as digital scanners or digital cameras, or by pixel editing programs, i.e. The basic difference between raster and vector is that a raster image is made up of pixels, whereas a vector image is made up of paths. Raster and vector are two different ways to draw up computer graphics. Key difference: A raster images uses different colored pixels, which are arranged in a manner to display an image.
