I remember seeing a tutorial on OpenCV on making an imagine out of a multiline string.

Example :

"""
001000000
001000000
001000000
001000000
001000000
001000000
"""

That would produce a black pixel for every 0 in the string, and a white pixel for the 1s.

Please tell me if I can give you more information!
