Advantages:
Vector Graphic was created in 1976.
Vector describes both speed and direction. In graphic programs, a vector graphic scales smoothly (more so than a bitmap image).
One possible categorization is in raster images and vector images.
Vector
Scalable Vector Graphic. SVG is a language for describing two-dimensional graphics in XML [XML10]. SVG allows for three types of graphic objects: vector graphic shapes (e.g., paths consisting of straight lines and curves), images and text. See related link for more information.
Raster and Vector
vector graphic you can change size and you don't loose nothing,you get bigger or smaller size and that's it,but bitmap are from pixels and you can make them smaller but not bigger,actually you can but with very bad results
We are a team of highly skilled, experienced graphic designers specializing in the field of vector graphics.
graphic software have more vector based capabilities
There are main two classes of graphics software. These graphic software classes include raster graphics, as well as vector graphics.
PICT
Photoshop can not save vector image but you can work with vector shapes inside Photoshop. There are many similarities, you can add elements to image like type, shape, change color... big difference is that you can not enlarge bitmap image without losing quality.
