Create Outline Text in Python with Pillow

Sometimes, we may want to add surrounding color to text strokes in Python. Prior to version 6.2.0, we can not do this in Pillow. Fortunately, starting from version 6.2.0, pillow now supports text outlines natively in the ImageDraw.text() method.

from PIL import Image, ImageFont, ImageDraw

def main():
    im = Image.new('RGB', (500, 500), (255, 255, 255))
    text = "测试文字"
    font = ImageFont.truetype(
        font="C:/WINDOWS/Fonts/STKAITI.TTF",
        size=70)
    drawer = ImageDraw.Draw(im)

    fill_color = (255, 0, 0)
    stroke_color = (0, 0, 255)

    drawer.text((50, 10), text, font=font, fill=fill_color, stroke_width=1, stroke_fill=stroke_color)
    drawer.text((50, 80), text, font=font, fill=fill_color, stroke_width=3, stroke_fill=stroke_color)
    drawer.text((50, 150), text, font=font, fill=fill_color, stroke_width=5, stroke_fill=stroke_color)
    drawer.text((50, 220), text, font=font, fill=fill_color, stroke_width=7, stroke_fill=stroke_color)

    im.show("text-image")

if __name__ == "__main__":
    main()

The parameter stroke_width controls the width of outline, and stroke_fill controls the outline color.

The above script will create the following image.
