yipeiwu_com6年前Python基础

本文实例讲述了python简单实现旋转图片的方法。分享给大家供大家参考。具体实现方法如下:

# 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")

希望本文所述对大家的Python程序设计有所帮助。
