Python PIL | ImageDraw.Draw.rectangle()
PIL 是Python Imaging Library，它为Python解释器提供了图像编辑功能。 ImageDraw模块为 Image 对象提供简单的 2D 图形。您可以使用此模块创建新图像、注释或修饰现有图像，以及动态生成图形以供 Web 使用。
ImageDraw.Draw.rectangle()绘制一个矩形。
Syntax: PIL.ImageDraw.Draw.rectangle(xy, fill=None, outline=None)
Parameters:
xy – Four points to define the bounding box. Sequence of either [(x0, y0), (x1, y1)] or [x0, y0, x1, y1]. The second point is just outside the drawn rectangle.
outline – Color to use for the outline.
fill – Color to use for the fill.
Returns: An Image object in rectangle shape.
# importing image object from PIL
import math
from PIL import Image, ImageDraw
w, h = 220, 190
shape = [(40, 40), (w - 10, h - 10)]
# creating new Image object
img = Image.new("RGB", (w, h))
# create rectangle image
img1 = ImageDraw.Draw(img)
img1.rectangle(shape, fill ="# ffff33", outline ="red")
img.show()
输出： _0.png)
另一个例子：这里我们使用不同的颜色进行填充。
# importing image object from PIL
import math
from PIL import Image, ImageDraw
w, h = 220, 190
shape = [(40, 40), (w - 10, h - 10)]
# creating new Image object
img = Image.new("RGB", (w, h))
# create rectangleimage
img1 = ImageDraw.Draw(img)
img1.rectangle(shape, fill ="# 800080", outline ="green")
img.show()
输出： _1.png)
