The image quality in vector-based graphics does not depend on the DPI of the output device. This type of artwork in graphic design is good for logo designs because the resulting image is clear and crisp. Vector-based graphics do not work well when there is a need for soft-toned graphics in a picture. A picture which requires a lot of tonal changes is difficult to achieve in vector art. If you are interested in adding a vector-based image on your web page then you need to rasterize the image (convert it into a bitmap image). But the vector images that are created in Flash can be used in a web page without converting it. Besides Flash, there are several plug-ins that are available which support vector-based images. In many cases, the browsing software faces trouble in dealing with a vector-based graphics and rasterizes the vector image itself.
Vector-based images cannot be for realistic pictures. This is very important to know that the conversion of pixel-based image into a vector-based image is very difficult. It can only be done by using specific software. It is wise to use bitmap images in graphics or for web design because images produced by scanners and digital devices are bitmap images and the conversion of pixel-based image into a vector image is a difficult task.
