坐标系和坐标转换Coordinate Systems and Transformations

GDI + 提供了世界转换和页转换,以便可以转换 (旋转、 缩放、 转换,等等) 所绘制的项。GDI+ provides a world transformation and a page transformation so that you can transform (rotate, scale, translate, and so on) the items you draw. 两种转换还可以在各种坐标系统中工作。The two transformations also allow you to work in a variety of coordinate systems.
