Python，用PIL画一个圆 [英] Python, Draw a circle with PIL

问题描述

我正在寻找一个使用PIL在现有图像上绘制圆的命令.

I am looking for a command that will draw a circle on an existing image with PIL.

im = Image.open(path)

我想要一个函数来绘制半径为r且中心为(x,y)

I want a function that will draw a colored circle with radius r and center (x,y)

推荐答案

image = Image.open("x.png")
draw = ImageDraw.Draw(image)
leftUpPoint = (x-r, y-r)
rightDownPoint = (x+r, y+r)
twoPointList = [leftUpPoint, rightDownPoint]
draw.ellipse(twoPointList, fill=(255,0,0,255))

请参考官方文档: PIL.ImageDraw.ImageDraw.ellipse(xy，fill = None，outline = None，width = 0)
