使用cairo（从此处获取了很多代码）：
import cairodef text_extent(font, font_size, text, *args, **kwargs): surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, 0, 0) ctx = cairo.Context(surface) ctx.select_font_face(font, *args, **kwargs) ctx.set_font_size(font_size) return ctx.text_extents(text)text='Example'font="Sans"font_size=55.0font_args=[cairo.FONT_SLANT_NORMAL](x_bearing, y_bearing, text_width, text_height, x_advance, y_advance) = text_extent(font, font_size, text, *font_args)surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, int(text_width), int(text_height))ctx = cairo.Context(surface)ctx.select_font_face(font, *font_args)ctx.set_font_size(font_size)ctx.move_to(-x_bearing, -y_bearing)ctx.text_path(text)ctx.set_source_rgb(0.47, 0.47, 0.47)ctx.fill_preserve()ctx.set_source_rgb(1, 0, 0)ctx.set_line_width(1.5)ctx.stroke()surface.write_to_png("/tmp/out.png")
