Based On Svg Technology, K-line Diagram Of The Design And Realization

Scalable Vector Graphics (SVG) is a World Wide Web Consortium (W3C) standard. it is also a text-based graphics language that describes images with vector shapes, text and embedded raster graphics. SVG is a subset of XML. This makes it very easy to incorporate SVG into Web sites and helps to ensure compatibility. Vector graphics have many advantages over bitmapped graphics. They scale well, retaining their resolution at any size and with any change of the viewing device. Text-based simply means that SVG, unlike most graphics standards, is coded with simple text, search engines can index SVG graphics according to what the diagram contains. Because SVG is XML-based, it can (using Java etc. to convert the data to SVG) render graphics from database data, so images can dynamically update, and SVG graphics can easily be animated, made interactive. Meanwhile, SVG graphics can be made accessible to people with visual disabilities by means of voice or Braille software, which can use the text description to describe the image. With these attributes of SVG, A K line graphics done in SVG is well than any graphics.Firstly, the paper ananlyse the develop of SVG technology. Then introduce the principle of SVG, introduce the structure and logical design of K line system based on Web. Finally, design and implement K line graphics accord to the logical design, introduce the technology of reliazing K line graphics base on SVG in detail.
