VB旋转图片，旋转任意的图像文件，实现思路：获得旋转的角度，将坐标轴原点移动到Picture1的中心后原来坐标为(x,y)，获得在更改坐标原点后旋转后该点的X坐标，获得恢复坐标原点后旋转后的Y坐标，将Picture1中(x,y)点复制到Picture2的(X3,Y3)点-VB rotate a picture, rotate any image file, realization of ideas: to get the angle of rotation, the axis moves to the center of origin Picture1 original coordinates (x, y), to obtain the coordinates of the X coordinate origin after changing the point of rotation , the origin of the coordinate obtained after recovery of the rotated Y coordinates of the Picture1 in (x, y) point to the copy of Picture2 (X3, Y3) point
