itp [image file]

itp finds primes which look similar to an image using the following steps:

• step 1: Convert the image into a number. Brightness chart is "7772299408".
• step 2: If last digit is even or 5 change it, otherwise number can't be a prime.
• step 3: If first digit is 0 change it. No redundant leading zeros allowed
• step 4: Check if number is prime. If it is a prime, print it and exit.
• step 5: If number is not prime, switch one of the digits with a similar one.
• step 6: Goto step 4.
