在python中逐个像素绘制圆

from PIL import Image, ImageDraw

width = 500  # 图像宽度
height = 500  # 图像高度
image = Image.new('RGB', (width, height), (255, 255, 255))  # 创建一个白色背景的图像

draw = ImageDraw.Draw(image)

center_x = 250  # 圆心的x坐标
center_y = 250  # 圆心的y坐标
radius = 100  # 圆的半径
color = (255, 0, 0)  # 圆的颜色，这里使用红色

for x in range(width):
    for y in range(height):
        if (x - center_x) ** 2 + (y - center_y) ** 2 <= radius ** 2:
            draw.point((x, y), fill=color)

image.save('circle.png')
