Python Program to Find the Size (Resolution) of Image

Here in this article, we have provided two different python source codes which can find the resolution of a jpeg image.

Prerequisite Python Program to Find the Size (Resolution) of Image

• Python Function
• Python File handling.
• Python PIL library
• Python user-defined function
• Python file I/O

Python Program to Find the Size (Resolution) of Image

Find the Size (Resolution) of a JPEG Image Without any External Library

def image_resolution(filename):

   # open image in binary mode
   with open(filename,'rb') as img:

       # height of image (in 2 bytes) is at 164th position
       img.seek(163)

       # read the 2 bytes
       x = img.read(2)

       # calculate height
       height = (x[0] << 8) +x[1]

       # next 2 bytes is width
       x = img.read(2)

       # calculate width
       width = (x[0] << 8) + x[1]

   print("Width X Height: ", width,"X",height)

image_resolution("image.jpg")

Output:

Width X Height: 57601 X 255

Find the Size (Resolution) of Image With PIL Library

Use the pip install PIL command to install the PIL library:

Code:

from PIL import Image
image = "Image.jpg"
img = Image.open(image)
width, height = img.size
print("The image resolution  is", width, "x", height)

Output:

The image resolution is 1333 x 1000
