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")
