python產生方形圖片的tip

代碼來自網友Jimmy Kuu和方石：import Imageimage = Image.open('01.jpg')image.thumbnail((48, 48), Image.ANTIALIAS)w, h = image.sizeif w == 48 and h == 48:    image.save('thumb.jpg')else:    image2 = Image.new(image.mode, (48, 48), (255, 255, 255))    if w < 48:        box = ((48 - w) / 2, 0, 24 + w / 2, 48)    else:        box = (0, (48 - h) / 2, 48, 24 + h / 2)    image2.paste(image, box)    image2.save('thumb.jpg')這個更好一點def get_Square_photo(imgname, outimgname, width):    """        @param imgname:    @param outimgname:    @param width:    """    img = Image.open(imgname, "r")      if img.size[0] > img.size[1]:        offset = int(img.size[0] - img.size[1]) / 2        img = img.transform((img.size[1], img.size[1]), EXTENT, (offset, 0, int(img.size[0] - offset), img.size[1]))    else:        offset = int(img.size[1] - img.size[0]) / 2        img = img.transform((img.size[0], img.size[0]), EXTENT, (0, offset, img.size[0], (img.size[1] - offset)))    img.thumbnail((width, width))    img.save(outimgname, 'png')
