Python PIL | ImageDraw.Draw.line()
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.line()在 xy 列表中的坐标之间绘制一条线。
Syntax: PIL.ImageDraw.Draw.line(xy, fill=None, width=0)
Parameters:
xy – Sequence of either 2-tuples like [(x, y), (x, y), …] or numeric values like [x, y, x, y, …].
fill – Color to use for the line.
width –The line width, in pixels. Note that line joins are not handled well, so wide polylines will not look good.
Returns: An Image object in ellipse 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 line image
img1 = ImageDraw.Draw(img)
img1.line(shape, fill ="none", width = 0)
img.show()
_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 line image
img1 = ImageDraw.Draw(img)
img1.line(shape, fill ="red", width = 0)
img.show()
输出： _1.png)
