How to change an image with Python

Today I would like to play a little bit with Python and Pillow library. I will test some possibilities of PIL.

I open PyCharm and I create in a directory PycharmProjects a project imagePython.
Normally PyCharm creates it automatically

I want to work with pictures so I install pillow for mac:

python3 -m pip install --upgrade pip python3 -m pip install --upgrade Pillow 

When I create a directory images and download a picture that I want to modify from Pixabay. It is better to chose a little image so it will take less time to transform it.

Now I change a main.py file:

from PIL import Image tulips = Image.open("./images/tulips.jpeg") tulips.show() 

and I run this code and this is a result:

That you see the image change a name and format.

Now I can rotate my image:

rotateImage = tulips.rotate(180) rotateImage.show() 

I can also resize it:

little = tulips.resize((128, 128)) little.show() 

Now I change colors to white and black:

# all is black and white im = tulips.convert("L") im.show() 

I can also change the colors of the image like this:

r, g, b = tulips.split() r = r.point(lambda i: i * 2) g = g.point(lambda i: i / 2) b = b.point(lambda i: i + 50) img = Image.merge("RGB", (r, g, b)) img.getextrema() img.show() 

There is possible to use also some filters like blur or contour and much more than you can find in documentation:

from PIL import ImageFilter im1 = tulips.filter(ImageFilter.BLUR) im1.show() im2 = tulips.filter(ImageFilter.CONTOUR) im2.show() 

I can also regulate the contrast of my image:

 from PIL import ImageEnhance # contrast of 50% contrastedImg = ImageEnhance.Contrast(tulips) contrastedImg.enhance(1.5).show() 

These are only some examples of Pillow possibilities so don't hesitate to test them and use them in your projects.
