I have no idea what the problem is, I'm trying to read an image and place the colour inside an array which I'll use as a height map later, but right now... How to get pixel colour into a two dimensional array.

Do we have to guess what the symptoms of the problem are or are you willing to share them?

Your for loop conditions are not correct. You are trying to set WIDTH + 1 and HEIGHT + 1 element, but you only have WIDTH and HEIGHT of them in your arrays.

The quieter you are, the more you are able to hear.

My silly mistake an array of 10 index's starts at 0 and ends at 9
I was going from 0 to one higher than the arrays length.

And the error was a arrayoutofbound
I agree. Here's the link:
