Microsoft DirectX 9.0

Border Color Texture Address Mode

The border color texture address mode, identified by the D3DTADDRESS_BORDER member of the D3DTEXTUREADDRESS enumerated type, causes Microsoft?Direct3D?to use an arbitrary color, known as the border color, for any texture coordinates outside the range of 0.0 through 1.0, inclusive.

This is shown in the following figure in which the application specifies that the texture be applied to the primitive using a red border.

Red border

Applications set the border color by calling IDirect3DDevice9::SetSamplerState. Set the first parameter for the call to the desired texture stage identifier, the second parameter to the D3DSAMP_BORDERCOLOR stage state value, and the third parameter to the new RGBA border color.
