在python中绘制多个PIL.Image

from PIL import Image, ImageDraw

width = 800
height = 600
background_color = (255, 255, 255)  # 白色背景
image = Image.new('RGB', (width, height), background_color)

draw = ImageDraw.Draw(image)

# 绘制直线
start_point = (100, 100)
end_point = (200, 200)
line_color = (0, 0, 0)  # 黑色线条
draw.line([start_point, end_point], fill=line_color)

# 绘制矩形
rectangle = (300, 300, 400, 400)
rectangle_color = (255, 0, 0)  # 红色矩形
draw.rectangle(rectangle, fill=rectangle_color)

# 绘制圆形
center = (500, 500)
radius = 50
circle_color = (0, 255, 0)  # 绿色圆形
draw.ellipse([(center[0]-radius, center[1]-radius), (center[0]+radius, center[1]+radius)], fill=circle_color)

image.save('output.png')
