How to convert a string to an image?

Question

I started to learn python a week ago and want to write a small program that converts a email to a image (.png) so that it can be shared on forums without risking to get lots

Answer 1

1. use ImageDraw.text - but it doesn't do any formating, it just prints string at the given location

   img = Image.new('RGB', (200, 100))
   d = ImageDraw.Draw(img)
   d.text((20, 20), 'Hello', fill=(255, 0, 0))
   

   to find out the text size:

   text_width, text_height = d.textsize('Hello')
   

2. When creating image, add an aditional argument with the required color (white):

   img = Image.new('RGB', (200, 100), (255, 255, 255))
   

3. until you save the image with Image.save method, there would be no file. Then it's only a matter of a proper transformation to put it into your GUI's format for display. This can be done by encoding the image into an in-memory image file:

   import cStringIO
   s = cStringIO.StringIO()
   img.save(s, 'png')
   in_memory_file = s.getvalue()
   

   or if you use python3:

   import io
   s = io.BytesIO()
   img.save(s, 'png')
   in_memory_file = s.getvalue()
   

   this can be then send to GUI. Or you can send direct raw bitmap data:

   raw_img_data = img.tostring()

The first 3 lines are not complete, when I'm not wrong. The correct code would be:

from PIL import Image
from PIL import ImageDraw
from PIL import ImageFont
