If the text is identical, same colors & size, then you could find the first char by scanning each pixel column. Then you could get the region of each character and see if all the pixels in that region matches. For each found character you append it to the string to return.

There are some text recognition libraries that might make it easier.

If you are looking to find a library then you could do a search for optical character recognition in VB.Net.

If you cant implement your way of using the library then you shouldn't start with such a hard thing
