ImageMagic
We will be using simple image processing with PIL library
use command below to install it:
python3 -m pip install pillow
opening an image file using PIL:
use command below to install it:
python3 -m pip install pillow
opening an image file using PIL:
from PIL import Image im = Image.open("images/egg.png") im.show() #delegates show image command to system's default image viewer
Save image:
from PIL import Image im = Image.open("images/egg.png") im.save("images/newegg.png")
Crop Image
from PIL import Image im = Image.open("images/egg.png") cropbox = 50, 50, 200, 200 im = im.crop(cropbox) im.save("images/cropegg.png")
Creating a thumbnail:
The filter argument can be one of NEAREST (use nearest neighbour), BILINEAR (linear interpolation in a 2x2 environment), BICUBIC (cubic spline interpolation in a 4x4 environment), or ANTIALIAS (a high-quality downsampling filter). If omitted, or if the image has mode “1” or “P”, it is set to NEAREST.

from PIL import Image im = Image.open("images/egg.png") size = (30, 30) im.thumbnail(size, Image.ANTIALIAS ) im.save("images/neweggthumb.png")

Rotate Image
from PIL import Image im = Image.open("images/egg.png") im = im.rotate(90) im.save("images/rotatedegg.png")
Blur Image
from PIL import Image from PIL import ImageFilter im = Image.open("images/egg.png") im = im.filter(ImageFilter.BLUR) im.save("images/eggblur.png")
The current version of the library provides the following set of predefined image enhancement filters:
BLUR, CONTOUR, DETAIL, EDGE_ENHANCE,EDGE_ENHANCE_MORE, EMBOSS, FIND_EDGES, SMOOTH,SMOOTH_MORE, and SHARPEN.
