PIL是Python Imaging Library,它為python解釋器提供了圖像編輯函數。PIL.Image.crop()
方法用於裁剪任何圖像的矩形部分。
用法: PIL.Image.crop(box = None)
參數:
box –定義左,上,右和下像素坐標的4元組。
返回類型:圖像(將矩形區域返回為(左,上,右,下)元組)。
返回:Image對象。
代碼1:
# Improting Image class from PIL module
from PIL import Image
# Opens a image in RGB mode
im = Image.open(r"C:\Users\Admin\Pictures\geeks.png")
# Size of the image in pixels (size of orginal image)
# (This is not mandatory)
width, height = im.size
# Setting the points for cropped image
left = 5
top = height / 4
right = 164
bottom = 3 * height / 4
# Cropped image of above dimension
# (It will not change orginal image)
im1 = im.crop((left, top, right, bottom))
# Shows the image in image viewer
im1.show()

代碼2:
# Improting Image class from PIL module
from PIL import Image
# Opens a image in RGB mode
im = Image.open(r"C:\Users\Admin\Pictures\network.png")
# Setting the points for cropped image
left = 155
top = 65
right = 360
bottom = 270
# Cropped image of above dimension
# (It will not change orginal image)
im1 = im.crop((left, top, right, bottom))
# Shows the image in image viewer
im1.show()
