NeHe Tutorial 6 bitmap problem

OpenGL OpenGL: Basic Coding
1

Hi all,

I’m learning OpenGL from the NEHe tutorials. #6 is about mapping a bmp onto a quad. works perfectly with his bmp. But my bmp that I made using Paint to convert from a jpg simply doesn’t work though the C code does open the file. I just get a white square. Can anyone suggest what migh cause this kind of problem.

Thanks.

Are the width and height of your bitmap both powers of two?

(they should be)…

No - it was 96 by 96 and changing it to 64 x 64 fixed it. Thanks for answering what must have seemed a basic question.
