Python OpenCV – cv2.rotate() method
OpenCV-Python is a library of Python bindings designed to solve computer vision problems.
cv2.rotate() method is used to rotate a 2D array in multiples of 90 degrees. The function cv::rotate rotates the array in three different ways.
Syntax: cv2.cv.rotate( src, rotateCode[, dst] )
src: It is the image whose color space is to be changed.
rotateCode: It is an enum to specify how to rotate the array.
dst: It is the output image of the same size and depth as src image. It is an optional parameter.
Return Value: It returns an image.
Image used for all the below examples:
Example #1: Rotate by 90 degrees clockwise
Example #2: Rotate by 180 degrees clockwise
Example #3: Rotate by 270 degrees clockwise
