创建文字PNG图片

from PIL import Image, ImageDraw, ImageFont

# 创建一个空白的图片
width, height = 200, 200
image = Image.new("RGB", (width, height), "white")
draw = ImageDraw.Draw(image)

# 设置字体和颜色
font = ImageFont.truetype("arial.ttf", 100)
text = "S"
color = "black"

# 计算文本的宽度和高度
text_width, text_height = draw.textsize(text, font)

# 计算文本的位置
x = (width - text_width) / 2
y = (height - text_height) / 2

# 在图片上绘制文本
draw.text((x, y), text, font=font, fill=color)

# 保存图片
image.save("sensor_logo.png")
