With the Vector Markup Language (VML), Web designers can easily edit, cut, and paste vector images into applications. This opportunity, according to Steve Sklepovich, product manager at Microsoft, is essential for users.Unlike raster images, which are images formed by arrays of pixels, vector images include lines, squares, and other geometric objects.Until now, those wishing to add vector images to their Web pages had to use raster image formats such as GIF, JPEG, and PNG. However, it was impossible to reduce or increase their size, even by expanding or shrinking the browser window.With VML, Web site designers can scale vector images on Web pages and load graphics much faster than bitmap images.
