How to create pictures in bitmap binary (-1,1) format?

Question

Neural networks

In other words, I have a task
"Sorting - Recognizing digits 5,6,8,9 in bitmap binary (-1,1) format - You must create 10x4 = 40
incomplete or distorted patterns (there is a perfect and incomplete pattern for each digit in the file)"

I would like to know if there are services where I can create such numbers in this resolution.
