D3DBLENDOP

Defines the supported blend operations.

typedef enum _D3DBLENDOP {
    D3DBLENDOP_ADD              = 1,
    D3DBLENDOP_SUBTRACT         = 2,
    D3DBLENDOP_REVSUBTRACT      = 3,
    D3DBLENDOP_MIN              = 4,
    D3DBLENDOP_MAX              = 5,

    D3DBLENDOP_FORCE_DWORD      = 0x7fffffff
} D3DBLENDOP;

Constants

D3DBLENDOP_ADD

The result is the destination added to the source.

Result = Source + Destination

D3DBLENDOP_SUBTRACT

The result is the destination subtracted from to the source.

Result = Source - Destination

D3DBLENDOP_REVSUBTRACT

The result is the source subtracted from the destination.

Result = Destination - Source

D3DBLENDOP_MIN

The result is the minimum of the source and destination.

Result = MIN(Source, Destination)

D3DBLENDOP_MAX

The result is the maximum of the source and destination.

Result = MAX(Source, Destination)

D3DBLENDOP_FORCE_DWORD

Forces this enumeration to compile to 32 bits in size. This value is not used.

Remarks

This enumerated type defines values used by the D3DRS_BLENDOP render state.
