![]() This means that an interface designer could create an interface for a TV which would work perfectly on both hand-held TV and a 72 inch plasma display. In 2001 the World Wide Web Consortium (W3C - the fine people who are responsible for steering the direction of the web) introduced the Scaleable Vector Graphics (SVG) 1.0 standard which can be used not only to draw shapes and manipulate them, but also to animate an interact with them. This type of image notation is know as vector graphics. The circle will always be drawn at the native resolution of the screen so it will look like a perfect circle, even if you then transfer it to a different screen. Noting that information in text (or any-other) form, we can draw that circle on any screen of any size. Imagine a circle with a radius of three units, a line width of one unit and a line colour of blue. So how can we describe graphics without using pixels? Mathematics of course! The problem with this is that while the image might look great on your camera phone's display, if you print it out on A3 paper you will easily be able to make out each individual pixel. Wouldn't it be nice to have a way where by you can create a web-page once and have it render crystal clear on every display, no matter the size or resolution? Standard graphic formats use pixels to generate the image - one image maybe made of many millions of pixels each with its own colour information. Wouldn't it be nice to have a way where by you can create a web-page once and have it render crystal clear on every display These problems presents several difficulties for the interface designer who wants his work, particularly that on the internet, to look similar on all screens. An added complication is the resolution of the display, one 14 inch display might have a much higher resolution than another display if it is a High Definition (HD) display. ![]() Computer screens may be 12 inches in the case of a smaller laptop or 30 inches for a large display. ![]() Mobile phones typically have screens which are 1.5 inches in size, while TVs vary from 14 to 72 inches. With new electronics products being launched everyday, there is a huge number of different display sizes and types.
