IMAGE ROTATION

rotate(image,angle)

image - Input Image
angle - cv2.ROTATE_90_COUNTERCLOCKWISE
cv2.ROTATE_180
cv2.ROTATE_90_CLOCKWISE

rot=getRotationMatrix2D(center,angle,scale)

center - center coordinates
angle - any angle
scale - scale factor

warpAffine(image,rot,(width,height))

Procedure

Step-1 : Import CV2
Step-2 : Read Image
Step-3 : Find Center Coordinates
Step-4 : Apply rotation using getRotationMatrix2D( )
Step-5 : Use Step-4 and rotate the input image using warpAffine( )
Step-6 : Write or Save Image
