Alright, guess I'll start this off simple...
This code is to make a picture out of Coordinates from a txt file...
the problem I'm having right now though, is that my fill function isn't working...
What is fill supposed to do? It takes a type of character we wish to fill, along with coordinates, and puts it into the image instead of the ' ' characters that are between said coordinates...
However, I'm having an issue getting it to print out the characters along with the image (I got it to print out the characters, but it then decided to erase those when the image was printed.)
I know there's something I'm missing, but I don't know what... and my head is getting all bloody from how many times its hit the monitor...
This is the Txt file I'm using
the file name is Final Assignment.txt

Any help would be greatly appreciated... also, sorry if my formatting is still "bad"... just I'm still getting the hang of it.
Frick, I fail... Meant to put this in Coding x.x
Tab Browsing got me x.x...
