In this solution we are going to Resize the image in Python. Python. Python has many libraries which provide the ability to work with Images .The image capabilities in Python include Image manipulation, enhancement etc. OpenCv comprehensive and popular Python library. In this solution kit, I am sharing the code snippet and library that I use to resize images using Opencv in Python which can be executed directly in the IDE.

width = 350
height = 450
dim = (width, height)

# resize image
resized = cv2.resize(img, dim, interpolation = cv2.INTER_AREA)

print('Resized Dimensions : ',resized.shape)

cv2.imshow("Resized image", resized)
cv2.waitKey(0)
cv2.destroyAllWindows()

Copy the code using the "Copy" button above, and paste it in a Python file in your IDE.
