Project description

Image operation utility


Installation using pip

$ pip install imgutil


  • jpegtran
  • pngcrush

Command line utilities


$ imgoptimize [-h] [-o OUTPUT] src_img
  • Optimize image to reduce file size.
  • Should install jpegtran and pngcrush.


  • -o: (Optional) Specifiy the output image.
  • src_img: Specify the input image.


$ imgresize [-h] [-o OUTPUT] [-W WIDTH] [-H HEIGHT] src_img
  • Resize image by specifying width or height.


  • -o: (Optional) Specifiy the output image.
  • -W or --width: (Optional) Specify the desired image width. If only width is specified, height will be determined by the aspect ratio of image.
  • -H or --height: (Optional) Specify the desired image height. If only height is specified, width will be determined by the aspect ratio of image.
  • src_img: Specify the input image.



imgoptimize(input_filename, output_filename=None)
  • Should install jpegtran and pngcrush.
  • It reduces jpeg/png file size.
  • It converts CMYK to RGB.

quick example

import os
from imgutil import imgoptimize

test_img = '/tmp/test.jpg'
os.stat(test_img).st_size              # 81073
imgoptimize(test_img, '/tmp/opt.jpg')  # output to /tmp/opt.jpg
os.stat('/tmp/opt.jpg').st_size        # 81026
imgoptimize(test_img)                  # optimize the original file
os.stat(test_img).st_size              # 81026


imgresize(input_filename, width=None, height=None, output_filename=None)
  • It can resize image and preserve aspect ratio.
  • It can resize image to specified dimension.

quick example

from imgutil import imgresize

test_img = '/tmp/test.jpg'    # It is a 1024x768 image
imgresize(test_img, width=600, output_filename='/tmp/resize.jpg') # /tmp/resize.jpg is 600x450
imgresize(test_img, height=600, output_filename='/tmp/resize.jpg') # /tmp/resize.jpg is 800x600
imgresize(test_img, width=100, height=100, output_filename='/tmp/resize.jpg') # /tmp/resize.jpg is 100x100
imgresize(test_img, width=200, height=400) # /tmp/test.jpg is 200x400 now
