Another application of the Python Image Library (PIL). This time we are loading an image and rotate it counterclockwise by a specified number of degrees. The image is shown rotated and then saved to the working folder. PIL handles a fair amount of image file formats easily.
# 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")
