Image mirroring

1. Implementation principle

Use cv2.flip() function to flip the image.

2. Implementation effect

cd ~/opencv

xxxxxxxxxx
python3 07.image_flip.py

Note: Select the image and press q to exit the program!

3. Implementation code

​x
import cv2
​
def flip_image(input_path, output_path, flip_code):
    image = cv2.imread(input_path)
    if image is None:
        print("Error: Unable to open image file.")
        return
    flipped_image = cv2.flip(image, flip_code)
    if cv2.imwrite(output_path, flipped_image):
        print(f"Image saved to {output_path}")
        cv2.imshow('Image Preview', cv2.imread(output_path))
        cv2.waitKey(0)
        cv2.destroyAllWindows()
    else:
        print("Error: Unable to save image file.")
