OpenCV-Python is a library of programming functions mainly aimed at real-time computer vision. cv2.flip() method is used to flip a 2D array. The function cv::flip flips a 2D array around vertical, horizontal, or both axes.
Syntax: cv2.cv.flip(src, flipCode[, dst] )
Parameters: src: Input array.
dst: Output array of the same size and type as src.
flip code: A flag to specify how to flip the array; 0 means flipping around the x-axis and positive value (for example, 1) means flipping around y-axis. Negative value (for example, -1) means flipping around both axes. Return Value: It returns an image.
Image used for all the below examples:
Example:
# Python program to explain cv2.flip() method # importing cv2 import cv2
# path path = r 'C:\Users\user\Desktop\geeks14.png'
# Reading an image in default mode src = cv2.imread(path)
# Window name in which image is displayed window_name = 'Image'
# Using cv2.flip() method # Use Flip code 0 to flip vertically image = cv2.flip(src, 0 )
# Displaying the image cv2.imshow(window_name, image) cv2.waitKey( 0 )
