pgmagick is a GraphicsMagick binding for Python. This module provides methods for Image Editing and Manipulation. pgmagick is written by Hideo Hattori.
We can do a lot of things using this library such as :

1. Resize, rotate, sharpen, color reduce, or add special effects to an image.
2. Create transparent image assets.
3. Compare two images.
4. Create a gradient image.
5. Draw Text.
6. Draw Text of 2 byte code.
7. Get image size
8. Edge extraction
9. Create GIF animation using images.
10. Add frames to image.
11. Converts images from one format to another.

Installation :
There are two ways to install pgmagick:

1. Windows: Execute following command in Command Prompt-

   pip install pgmagick
   

2. Ubuntu : Execute the following command in Terminal-

   ### Ubuntu11.10+ ###
   $ apt-get install python-pgmagick
   
   ### Ubuntu10.04+ ###
   $ apt-get install libgraphicsmagick++1-dev
   $ apt-get install libboost-python1.40-dev
   

Example#1: Let’s discuss a code to resize the image-

For illustration purpose I have taken following sample image-

Output:

Example#2: Let’s discuss a code to scale the image-
I have used the same sample image for input as in above example.

if you try running the code at your end, you will see that the image is successfully resampled as per the new dimensions and you will get a new image.
