如何使用python绘制曲线文本？将文本转换为曲线图像？

import matplotlib.pyplot as plt
import numpy as np
from PIL import Image, ImageDraw, ImageFont

width, height = 800, 400
image = Image.new('RGB', (width, height), (255, 255, 255))
draw = ImageDraw.Draw(image)

font_path = 'path_to_font_file.ttf'  # 替换为实际的字体文件路径
font_size = 50
font = ImageFont.truetype(font_path, font_size)

text = "Hello, World!"

text_width, text_height = draw.textsize(text, font=font)

start_x = (width - text_width) // 2
start_y = height // 2 - text_height // 2
end_x = start_x + text_width
end_y = start_y + text_height

draw.text((start_x, start_y), text, font=font, fill=(0, 0, 0))

data = np.array(image)
gray_data = np.mean(data, axis=2)
x, y = np.nonzero(gray_data < 128)
curve = np.polyfit(x, y, deg=10)  # 曲线拟合，可以调整多项式的阶数
curve_y = np.polyval(curve, x)
curve_image = Image.new('RGB', (width, height), (255, 255, 255))
curve_draw = ImageDraw.Draw(curve_image)
curve_draw.line(list(zip(x, curve_y)), fill=(0, 0, 0), width=1)

plt.imshow(curve_image)
plt.axis('off')
plt.show()
# 或者保存为文件
curve_image.save('curve_image.png')
