Hi,
I’m using the texture matrix and the CLAMP_TO_BORDER texture wrapping parameter in order to set the correct pixel-aspect-ratio of an image on a texture, hiding the superfluous pixels with the default TEXTURE_BORDER_COLOR. The problem is that on some platform using the DRI, CLAMP_TO_BORDER which is OpenGL 1.3 specific doesn’t exist as an extension, and I want to keep the same behavior.
Do you know the best method to simulate CLAMP_TO_BORDER on those OpenGL 1.2 platforms ?
Regards.
