Script to reduce the size of image files using the OpenCV library of python.
Prerequisites:
- openCV library
pip install opencv-python
Run the Script:
- Add the image in jpg format with name as ‘input.jpg’ in this folder.
- Run reduce_image_size.py script.
- resized output image will be generated in this folder.
Source Code:
reduce_image_size.py
# import openCV library for image handling
import cv2
# read image to be resized by imread() function of openCV library
img = cv2.imread('input.jpg')
print(img.shape)
# set the ratio of resized image
k = 5
width = int((img.shape[1])/k)
height = int((img.shape[0])/k)
# resize the image by resize() function of openCV library
scaled = cv2.resize(img, (width, height), interpolation=cv2.INTER_AREA)
print(scaled.shape)
# show the resized image using imshow() function of openCV library
cv2.imshow("Output", scaled)
cv2.waitKey(500)
cv2.destroyAllWindows()
# get the resized image output by imwrite() function of openCV library
cv2.imwrite('resized_output_image.jpg', scaled)
