Thank you, with that explanation I finally understand where you trying
to get to. And the code that I pointed you to should work quite well for
that purpose. My feeling is still that your code that is calling this
has a problem. If you want you can send me the code off line and I have
a quick look at what may go wrong here.

Ok. Let me clear it for once. I am trying to render image using
opengl, that we normally do for games. Opengl do not speak nsimage.
They speak textures . All i needed is magic piece of code that
converts every image to raw rbga or rbg data. In mac they do using
coreimage framework. But its ok. I can live happily without
gray scale images. White image is sufficient. Thanks to everybodies
time.

Sorry, I still don't understand your problem. Why are you converting
the
image? The standard code should work fine in displaying it. Actually
the
code I pointed you to is used for that.
From your screen shot I would expect that your drawing code uses the
wrong sizes. To verify this it would help if you sent a bit more of
your
code.

PS: For drawing pre-multiplied images get used. Better convert in to
that format. But this is completely unrelated to your problem.
