The way that I remember it is that 90 degrees and 270 degrees are basically the opposite of each other. So, (-b, a) is for 90 degrees and (b, -a) is for 270. 180 degrees and 360 degrees are also opposites of each other. 180 degrees is (-a, -b) and 360 is (a, b). 360 degrees doesn't change since it is a full rotation or a full circle.

Knowing how to apply this rotation inside and outside the Cartesian plane will open a wide range of applications in geometry, particularly when graphing more complex functions. Set the rotation angle in degrees. Rotate an Image by π/4 Radians Clockwise. This example rotates an image by -0.79 radians. In other words, the image gets rotated by -45 degrees. The formula for converting radians to degrees is the following: -45 deg = -0.79 rad x 180° / π. The minus sign makes it rotate in the clockwise direction. Note: Rotating a figure about the origin can be a little tricky, but this tutorial can help! This tutorial shows you how to rotate coordinates from the original figure about the origin. Then, simply connect the points to create the new figure. See this process in action by watching this tutorial!enum RotateFlags { ROTATE_90_CLOCKWISE = 0, //Rotate 90 degrees clockwise ROTATE_180 = 1, //Rotate 180 degrees clockwise ROTATE_90_COUNTERCLOCKWISE = 2, //Rotate 270 degrees clockwise }; Original Answer & Arbitrary degree rotation: You can also do this by using flip and transpose operation, ie for 90CW:"Center" is the 'center of rotation.' This is the point around which you are performing your mathematical rotation. "Degrees" stands for how many degrees you should rotate. A positive number usually by convention means counter clockwise. A rotation is a direct isometry , which means that both the distance and orientation are preserved.103. As of OpenCV3.2, life just got a bit easier, you can now rotate an image in a single line of code: cv::rotate(image, image, cv::ROTATE_90_CLOCKWISE); For the direction you can choose any of the following: ROTATE_90_CLOCKWISE.
