How to use gluScaleImage() ?

[B_old]

Hi.
I want to use gluScaleImage() to make my textures smaller.
But how do I use it?
This is what I does:



gluScaleImage(GL_TEXTURE_2D, Image->Width, Image->Height,
ColorType, Image->Data, 64,
64, ColorType, Image->Data)

And it gives me an error.
Does the ratio matter?
I do this after loading my TGA and before loading the data up to OGL.
Thanks for any advice.

Check out some documentation (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/opengl/glufnc01_3k4l.asp) about gluScaleImage. First parameter is wrong. And don't pass the same pointer for in and out image. Allocate a new buffer for the scaled image.

Thanks for the hint!
I'll check it out!

EDIT:
Thanks again, works fine.
