python旋转图片的代码详解编程语言

# rotate an image counter-clockwise using the PIL image library 

# free from: http://www.pythonware.com/products/pil/index.htm 

# make sure to install PIL after your regular python package is installed 

import Image 

# open an image file (.bmp,.jpg,.png,.gif) 

# change image filename to something you have in the working folder 

im1 = Image.open("Donald.gif") 

# rotate 60 degrees counter-clockwise 

im2 = im1.rotate(60) 

# brings up the modified image in a viewer, simply saves the image as 

# a bitmap to a temporary file and calls viewer associated with .bmp 

# make certain you have an image viewer associated with this file type 

im2.show() 

# save the rotated image as d.gif to the working folder 

# you can save in several different image formats, try d.jpg or d.png 

# PIL is pretty powerful stuff and figures it out from the extension 

im2.save("d.gif")
