用PIL绘制粗体/斜体文字？

from PIL import Image, ImageDraw, ImageFont

# 创建一个空白图像
image = Image.new('RGB', (500, 200), (255, 255, 255))
draw = ImageDraw.Draw(image)

# 设置字体和字体大小
font = ImageFont.truetype('path_to_font_file.ttf', size=40)

# 绘制粗体文字
draw.text((50, 50), "Bold Text", font=font, fill=(0, 0, 0), align='left', anchor='nw', stroke_width=2, stroke_fill=(255, 0, 0))

# 绘制斜体文字
italic_font = ImageFont.truetype('path_to_font_file.ttf', size=40, italic=True)
draw.text((50, 100), "Italic Text", font=italic_font, fill=(0, 0, 0), align='left', anchor='nw', stroke_width=2, stroke_fill=(255, 0, 0))

# 显示图像
image.show()
