OpenCV 4下的图像变换，可以进行图像的旋转操作。-OpenCV 4 transform the image, the image can operate rotation.

自己写的对图像的历史记录类,历史记录保存文件类，图像剪切类,包含图像的镜像,翻转旋转等-Write your own image for the history class, history class to save the file, image cut class, that contains a mirror image, flip rotation

此代码实现了图象的平移,旋转,镜像,转置,缩放等几何变换算法,-This code implements the image translation, rotation, mirror, transpose, geometric transformation algorithms such as scaling,
