使用PIL在照片上绘制圆角

from PIL import Image, ImageDraw

def rounded_corner(image, radius):
    # 获取图像的宽度和高度
    width, height = image.size

    # 创建一个新的图像，并在其中绘制圆角
    new_image = Image.new('RGBA', (width, height), (0, 0, 0, 0))
    draw = ImageDraw.Draw(new_image)
    draw.pieslice((0, 0, radius, radius), 180, 270, fill=(255, 255, 255, 255))
    draw.pieslice((width - radius, 0, width, radius), 270, 360, fill=(255, 255, 255, 255))
    draw.pieslice((0, height - radius, radius, height), 90, 180, fill=(255, 255, 255, 255))
    draw.pieslice((width - radius, height - radius, width, height), 0, 90, fill=(255, 255, 255, 255))
    draw.rectangle((radius / 2, 0, width - (radius / 2), height), fill=(255, 255, 255, 255))
    draw.rectangle((0, radius / 2, width, height - (radius / 2)), fill=(255, 255, 255, 255))

    # 将原始图像绘制到新图像上
    new_image.paste(image, (0, 0), image)

    return new_image

image = Image.open('image.jpg')
radius = 20
rounded_image = rounded_corner(image, radius)
rounded_image.save('rounded_image.png')
