A true innovation in web graphics is brewing. It will bring the rich, compelling, high-resolution graphics that we currently enjoy in the print world to web publishing.
Pixel graphics lose quality under certain conditions such as zooming.
SVG, on the other hand, is entirely based on XML, which makes it immune to pixel-related constraints. Vector graphics, on the other hand, describe shapes and paths only, which is more efficient. Unfortunately until we have an official SVG web standard, our only options are proprietary vector graphic standards such as Flash and QuickTime. The SVG standard is currently a working draft at the W3C, with group members coming from key industry players such as Adobe, HP, IBM, Macromedia, Microsoft, Netscape, Quark, Sun and Visio. The official W3C recommendation will follow.
