python旋转图片的代码

# 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")</pre>
