texturing problem

[powerpad]

I want to texture a simple quad with a texture loaded from an img (in .Net with C#)

1. I load the bitmap
2. I call

Gl.glTexImage2D(Gl.GL_TEXTURE_2D, 0, 3, this.iTexWidth, this.iTexWidth, 0, Gl.GL_BGR_EXT, Gl.GL_UNSIGNED_BYTE, this.tex2.getImageData());3. and I set the quad with

Gl.glBegin(Gl.GL_QUADS);
Gl.glTexCoord2f(0.0f, 1.0f);
Gl.glVertex3f(0.0f, 0.0f, 0.0f);
Gl.glTexCoord2f(1.0f, 1.0f); Gl.glVertex3f(5.0f, 0.0f, 0.0f);
Gl.glTexCoord2f(1.0f, 0.0f); Gl.glVertex3f(5.0f, 5.0f, 0.0f);

Gl.glTexCoord2f(0.0f, 0.0f);
Gl.glVertex3f(0.0f, 5.0f, 0.0f);

Gl.glEnd(); but I get a quad with a mirrored texture - which is not the intented result ... has anyone suggestions here ....
tnx

just change glTexCoord.
(0, 0) should go the bottom left vertex
and (1, 1) to top right. Just play a bit with the other two and you should figure it out.
Texture Coordinates define how the image is applied to the object.

I flipped them and this help but the other reason why I asked this was, what about glDrawPixels()

one can't assign texture coordinates to this function only "manual" flipping.

And I tried code from nehe's tutorial on texture mapping and even this has the same problem
- thanks for the fast answer
