pgmagick Python- Introduction and Installation

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- Python3 1==

from pgmagick import Image

#Include full path to the input image
img = Image('input_image.jpg')  
img.filterType(FilterTypes.SincFilter)
img.resize('150x150')
img.write('output_image.jpg')

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. Python3 1==

from pgmagick import Image

#Include full path to the input image
img = Image('input_image.jpg') 
img.quality(100)
img.scale('100x100')
img.sharpen(1.0)
img.write('output_image.jpg')

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. References:
