python旋转图片和压缩像素的方法

img = Image.open(path)   

if img.size[0] > img.size[1]:

    im_rotate = img.rotate(90, expand=True)

    size = (int(im_rotate.size[0] / 3), int(im_rotate.size[1] / 3))

    im_rotate = im_rotate.resize(size)

    im_rotate.save(savepath, quality=95)

else:

    size = (int(img.size[0] / 3), int(img.size[1] / 3))

    img = img.resize(size)

    img.save(savepath, quality=95)
