坐标空间及其变换
在视图和窗口中绘图或定位总是在一个二维坐标系进行，依据作用方法的不同，坐标有多种表示方法，并且各种不同坐标之间可以相互转换。-Coordinate Space and Transformation in the view and window graphics or positioning is always in a two-dimensional coordinate system, based on the role of the different methods, the coordinates that have a variety of methods, and a variety of mutual conversion between the coordinates.
