python - Wrap text in PIL

Question

I'm using PIL to draw text on an image. How would I wrap a string of text. This is my code:

text = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

image = Image.open("/tmp/background-image.jpg")
draw = ImageDraw.Draw(image)
font = ImageFont.truetype("/usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf"), 50, encoding='unic')
draw.text((100, 100), text, font=font, fill="#aa0000")
image.save("/tmp/image.jpg")

Answer 1

You will need to first split the text into lines of the right length, and then draw each line individually.

The second part is easy, but the first part may be quite tricky to do accurately if varible-width fonts are used. If fixed-width fonts are used, or if accuracy doesn't matter that much, then you can just use the textwrap module to split the text into lines of a given character width:

margin = offset = 40
for line in textwrap.wrap(text, width=40):
    draw.text((margin, offset), line, font=font, fill="#aa0000")
    offset += font.getsize(line)[1]
