glDrawPixels Only Drawing one Element
This seems simple enough, but here goes:
I am reading glReadPixels correctly, but when I try to write to the screen, i only am able to write one color, which is what ever color is in the bottom right hand corner. I specified to opengl that i want to read a section at the lower corner, and i can see by outputting the data that its reading correctly.
But i don't change the value of the pixels.
When I call glDrawPixels, its doesn't copy the array properly, it just uses one value and copies that value across the width and height.
I have these two flags set:
I'm not sure if i'm missing anything else.
Thanks for the help.
