As a very important means in raster-to-vector conversion of engineering drawing, the technique of mixture edition of raster and vector is more and more attached importance to.
作为工程图样矢量转换过程中一个十分重要的手段，光栅图像与矢量图形的混合编辑技术越来越受到人们的重视。
Vector data require far less storage than raster data because arc node lists simplify and reduce the data required to make sense of the features contained in the map.
矢量数据要求的存储要比栅格数据少得多，因为弧节点列表简化并减少了表示地图中包含的特征所需的数据。
Vector images can be blown up to any size without loss of quality. Raster (or Bitmap) images become jagged when made larger.
矢量图无论放大多少都不会损失图片质量，而光栅图(或位图)一旦放大就会出现锯齿。
