Answer:
In computer graphics images can be represented in two ways — using raster graphics (or bitmap) or vector graphics. The former is the representation of images as an array of pixlels, and the latter uses paths, points, lines, curves and shapes or polygons (which are all based upon mathematical equations) for the same purpose. Raster images are based on pixels and thus scale with loss of clarity, while vector-based images can be scaled indefinitely without degrading. In other words, vector graphics are resolution-independent and thus can remain the highest quality at any scale.
for people who need to create high-end flowcharts, engineering drawings, and other intricate illustrations. ConceptDraw’s libraries include thousands of scalable objects. If you have enough resources for a powerful leading vector graphics editor, ConceptDraw is definitely an option worth considering.
ZeusDraw (Mac)
ZeusDraw
ZeusDraw is a new vector drawing program with a fluid, graceful interface, great brushes and a host of other features. It requires Mac OS X 10.4 or higher. ZeusDraw is a Universal Binary and can be run on Intel or PowerPC. Its current version is 1.3.1.
Quartz and Cocoa let ZeusDraw show you what you are doing as you do it. When you move or rotate an object, you see the object move or rotate, not its bounding box. ZeusDraw has a selection of vector brushes (smooth, shaded, multi-hair), and it also has an object brush that allows you to paint with any piece of artwork,
