实现图像的平移，平移量应该可调(即用一个向量或两个标量保存平移量)，并显示对图像“view”的处理结果。实现图像的缩放，缩放系数可调，分别用两个变量或一个向量保存水平和垂直方向的缩放系数，并显示对图像“view”的处理结果。

-The image of the pan, pan, volume should be adjustable (ie, a vector or two scalar to save the translation amount), and display the results on the image of the " view" . Image zoom, adjustable zoom factor, respectively, with a scaling factor of two variables or a vector to save both horizontally and vertically, and display the results on the image of the " view" .
