Constants

D3DPBLENDCAPS_ZERO

Blend factor is (0, 0, 0, 0).

D3DPBLENDCAPS_ONE

Blend factor is (1, 1, 1, 1).

D3DPBLENDCAPS_SRCCOLOR

Blend factor is (R_s, G_s, B_s, A_s).

D3DPBLENDCAPS_INVSRCCOLOR

Blend factor is (1–R_d, 1–G_d, 1–B_d, 1–A_d).

D3DPBLENDCAPS_SRCALPHA

Blend factor is (A_s, A_s, A_s, A_s).

D3DPBLENDCAPS_INVSRCALPHA

Blend factor is (1–A_s, 1–A_s, 1–A_s, 1–A_s).

D3DPBLENDCAPS_DESTALPHA

Blend factor is (A_d, A_d, A_d, A_d).

D3DPBLENDCAPS_INVDESTALPHA

Blend factor is (1–A_d, 1–A_d, 1–A_d, 1–A_d).

D3DPBLENDCAPS_DESTCOLOR

Blend factor is (R_d, G_d, B_d, A_d).

D3DPBLENDCAPS_INVDESTCOLOR

Blend factor is (1–R_d, 1–G_d, 1–B_d, 1–A_d).

D3DPBLENDCAPS_SRCALPHASAT

Blend factor is (f, f, f, 1); f = min(A_s, 1-A_d).

D3DPBLENDCAPS_BOTHSRCALPHA

The driver supports the D3DBLEND_BOTHSRCALPHA blend mode. (This blend mode is obsolete. For more information, see CONST_D3DBLEND.)

D3DPBLENDCAPS_BOTHINVSRCALPHA

Source blend factor is (1–A_s, 1–A_s, 1–A_s, 1–A_s), and destination blend factor is (A_s, A_s, A_s, A_s); the destination blend selection is overridden.

Remarks

The RGBA values of the source and destination are indicated by the subscripts s and d.

The values in this enumeration define the values for the SrcBlendCaps member of D3DCAPS8.
