OpenGL C#, loading textures in upside down

Is there a way to load images into openGL with the y-coords flipped? (upside down). I'm using the .NET Bitmap and BitmapData classes, and passing BitmapData.Scan0 to OpenGL.

Flipping the Bitmap on the CPU using .RotateFlip() is too slow.

Aside from flipping all of the texcoords, can I solve this problem in our engine?

Solution

  • I think the answer is no. OpenGl takes a pointer to an image as texture data, and I never seen any way to tell him to flip the lines.
