有没有办法在python中为图像制作漂亮的抗锯齿圆角？

from PIL import Image, ImageDraw

def add_rounded_corners(image_path, output_path, corner_radius):
    img = Image.open(image_path)
    img = img.convert("RGBA")
    img_draw = ImageDraw.Draw(img)

    x, y = img.size
    alpha = Image.new('L', img.size, 255)
    draw = ImageDraw.Draw(alpha)
    draw.pieslice([0, 0, x, y], 180, 270, fill=255)
    draw.pieslice([0, 0, corner_radius, corner_radius], 180, 270, fill=0)
    img.putalpha(alpha)

    img.save(output_path)

image_path = "path/to/your/image.png"
output_path = "path/to/your/output/image.png"
corner_radius = 50
add_rounded_corners(image_path, output_path, corner_radius)
