Python Processing Pictures

PIL is the most common image processing library in Python, the PIL module in Python 2.x, replaced with pillow module in Python 3.x, installing Pil:pip install Pillow

1, Python view some properties of the picture

#!/usr/bin/env python#-*-coding:utf-8-*-From PILImportImageimage= Image.Open("dora.jpg")#open a Picture objectPrint(Image.format)#view the format of the image with the result ' JPEG 'Print(image.size)#View the size of the picture, and the result is (800,450) pixels of width and height, respectivelyPrint(Image.mode)#View the mode of the picture, the result is ' RGB ', other modes are bitmap mode, grayscale mode, Duotone mode, etc.

2. Python Resize Image

# !/usr/bin/env python#-*-coding:utf-8-*-  import= Image. Open ("dora.jpg")    # Open a Picture object  = Image.resize ((+))    # Adjust the picture to a width of 128 pixels, 128 pixels high
Out.show ()                        # view pictures

3. Python Rotate Picture

# !/usr/bin/env python#-*-coding:utf-8-*-  import= Image. Open ("dora.jpg")    # open a Picture object out = image.rotate            #  rotate the picture counterclockwise 45 degrees out.show ()                        # View pictures

4. Python Flip Picture

# !/usr/bin/env python#-*-coding:utf-8-*-  import= Image. Open ("dora.jpg")                  # open a Picture object out = Image.transpose (image.flip_left_right)    #  Flip the picture around if you want to flip the argument up and down to ' Image.flip_top_bottom 'out.show ()                                      #  View pictures
