Rotates a 2D array in multiples of 90 degrees

dst = cv.rotate(src, rotateCode)

Input

• src input array.
• rotateCode an enum to specify how to rotate the array:
  • 90CW Rotate 90 degrees clockwise
  • 180 Rotate 180 degrees clockwise
  • 90CCW Rotate 270 degrees clockwise

Output

• dst output array of the same type as src. The size is the same with '180', and the rows and cols are switched for '90CW' and '90CCW'.

The function cv.rotate rotates the array in one of three different ways:

• Rotate by 90 degrees clockwise (rotateCode = '90CW').
• Rotate by 180 degrees clockwise (rotateCode = '180').
• Rotate by 270 degrees clockwise (rotateCode = '90CCW').
