Python中用PIL/Pillow旋轉圖片

如果你的系統沒有安裝Pillow模塊，安裝：

 

pip install pillow

 

逆時針方向旋轉

# 導入 Pillow:
from PIL import Image
 
# 加載原始圖片
img = Image.open("rubberwhale1.png")
 
# 逆時針方向旋轉
img2 = img.rotate(45)
img2.save("rubberwhale2.jpg")
img3 = img.rotate(90)
img3.save("rubberwhale3.jpg")

 

順時針旋轉

img4 = img.rotate(-45)
img4.save("rubberwhale4.jpg")

 

 

關閉裁剪

img5 = img.rotate(45, expand=True)
img5.save("rubberwhale5.jpg")

 

重采樣過濾

近鄰取樣（默認）

 

img6 = img.rotate(45, resample=Image.NEAREST)
img6.save("rubberwhale6.jpg")

 

 

線性插值

img7 = img.rotate(45, resample=Image.BILINEAR)
img7.save("rubberwhale7.jpg")

 

三次樣條插值

img8 = img.rotate(45, resample=Image.BICUBIC)
img8.save("rubberwhale8.jpg")
