SVG矢量图形编辑系统,SVG严格遵从XML语法，并用文本格式的描述性语言来描述图像内容，因此是一种和图像分辨率无关的矢量图形格式。SVG格式具有以下优点：
图像文件可读，易于修改和编辑与现有技术可以互动融合。另外，SVG文件还可嵌入Javas cript，从而实现基于内容的图像搜索SVG图形格式支持多种滤镜和特殊效果，在不改变图像内容的前提下可以实现位图格式中类似文字阴影的效果
SVG图形格式可以用来动态生成图形。(SVG vector graphics editing system, SVG strictly follows the XML syntax, and describes the content of the image in a text format descr iption language. Therefore, it is a vector graphics format independent of the image resolution. The SVG format has the following advantages:
The image file is readable, easy to modify and edit, and can be fused with existing technology. In addition, the SVG file can also be embedded in Javas cript, so as to realize the content-based image search SVG graphics format support a variety of filters and special effects based on the precondition of not changing the content of the image can be achieved under the effect of similar text shadow bitmap format
SVG graphics formats can be used to dynamically generate graphics.)
