Blend factor is (f, f, f, 1); where f = min(Aₛ, 1 - Ad).
D3DBLEND_BOTHSRCALPHA
12
Obsolete. Starting with DirectX 6, you can achieve the same effect by setting the source and destination blend factors to D3DBLEND_SRCALPHA and D3DBLEND_INVSRCALPHA in separate calls.
D3DBLEND_BOTHINVSRCALPHA
13
Obsolete. Source blend factor is (1 - Aₛ, 1 - Aₛ, 1 - Aₛ, 1 - Aₛ), and destination blend factor is (Aₛ, Aₛ, Aₛ, Aₛ); the destination blend selection is overridden. This blend mode is supported only for the D3DRS_SRCBLEND render state.
D3DBLEND_BLENDFACTOR
14
Constant color blending factor used by the frame-buffer blender. This blend mode is supported only if D3DPBLENDCAPS_BLENDFACTOR is set in the SrcBlendCaps or DestBlendCaps members of D3DCAPS9.
D3DBLEND_INVBLENDFACTOR
15
Inverted constant color-blending factor used by the frame-buffer blender. This blend mode is supported only if the D3DPBLENDCAPS_BLENDFACTOR bit is set in the SrcBlendCaps or DestBlendCaps members of D3DCAPS9.
D3DBLEND_SRCCOLOR2
16
Blend factor is (PSOutColor[1]r, PSOutColor[1]g, PSOutColor[1]b, not used). See Render Target Blending. This flag is available in Direct3D 9Ex only.
D3DBLEND_INVSRCCOLOR2
17
Blend factor is (1 - PSOutColor[1]r, 1 - PSOutColor[1]g, 1 - PSOutColor[1]b, not used)). See Render Target Blending. This flag is available in Direct3D 9Ex only.
D3DBLEND_FORCE_DWORD
0x7FFFFFFF
Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. This value is not used.
The result is the destination added to the source. Result = Source + Destination
D3DBLENDOP_SUBTRACT
2
The result is the destination subtracted from to the source. Result = Source - Destination
D3DBLENDOP_REVSUBTRACT
3
The result is the source subtracted from the destination. Result = Destination - Source
D3DBLENDOP_MIN
4
The result is the minimum of the source and destination. Result = MIN(Source, Destination)
D3DBLENDOP_MAX
5
The result is the maximum of the source and destination. Result = MAX(Source, Destination)
D3DBLENDOP_FORCE_DWORD
0x7FFFFFFF
Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. This value is not used.
Accept the new pixel if its value is less than the value of the current pixel.
D3DCMP_EQUAL
3
Accept the new pixel if its value equals the value of the current pixel.
D3DCMP_LESSEQUAL
4
Accept the new pixel if its value is less than or equal to the value of the current pixel.
D3DCMP_GREATER
5
Accept the new pixel if its value is greater than the value of the current pixel.
D3DCMP_NOTEQUAL
6
Accept the new pixel if its value does not equal the value of the current pixel.
D3DCMP_GREATEREQUAL
7
Accept the new pixel if its value is greater than or equal to the value of the current pixel.
D3DCMP_ALWAYS
8
Always pass the test.
D3DCMP_FORCE_DWORD
0x7FFFFFFF
Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. This value is not used.
Do not update the entry in the stencil buffer. This is the default value.
D3DSTENCILOP_ZERO
2
Set the stencil-buffer entry to 0.
D3DSTENCILOP_REPLACE
3
Replace the stencil-buffer entry with a reference value.
D3DSTENCILOP_INCRSAT
4
Increment the stencil-buffer entry, clamping to the maximum value.
D3DSTENCILOP_DECRSAT
5
Decrement the stencil-buffer entry, clamping to zero.
D3DSTENCILOP_INVERT
6
Invert the bits in the stencil-buffer entry.
D3DSTENCILOP_INCR
7
Increment the stencil-buffer entry, wrapping to zero if the new value exceeds the maximum value.
D3DSTENCILOP_DECR
8
Decrement the stencil-buffer entry, wrapping to the maximum value if the new value is less than zero.
D3DSTENCILOP_FORCE_DWORD
0x7FFFFFFF
Forces this enumeration to compile to 32 bits in size. Without this value, some compilers would allow this enumeration to compile to a size other than 32 bits. This value is not used.
