图片的操作： import media path = media.choose_file() pic = media.load_picture(path) media.show(pic) for p in media.get_pixels(pic): new_blue = int(0.6 * media.get_blue(p)) new_green = int(0.6 * media.get_green(p)) media.set_blue(p, new_blue) media.set_green(p, new_green) media.show(pic) print pic.title new_name = raw_input("Enter the name to save the new file:") new_name += '.jpg' media.save_as(pic, new_name) print pic.title
将图片的每个像素的蓝 {MOD}和绿 {MOD}降低为原来的60%，以便让图片看起来更暗，更红些。像是在暮光下拍的。
