D3DSTENCILOP enumeration

Defines stencil-buffer operations.

Syntax

typedef enum D3DSTENCILOP { 
  D3DSTENCILOP_KEEP         = 1,
  D3DSTENCILOP_ZERO         = 2,
  D3DSTENCILOP_REPLACE      = 3,
  D3DSTENCILOP_INCRSAT      = 4,
  D3DSTENCILOP_DECRSAT      = 5,
  D3DSTENCILOP_INVERT       = 6,
  D3DSTENCILOP_INCR         = 7,
  D3DSTENCILOP_DECR         = 8,
  D3DSTENCILOP_FORCE_DWORD  = 0x7fffffff
} D3DSTENCILOP, *LPD3DSTENCILOP;

Constants

D3DSTENCILOP_KEEP

Do not update the entry in the stencil buffer. This is the default value.

D3DSTENCILOP_ZERO

Set the stencil-buffer entry to 0.

D3DSTENCILOP_REPLACE

Replace the stencil-buffer entry with a reference value.

D3DSTENCILOP_INCRSAT

Increment the stencil-buffer entry, clamping to the maximum value.

D3DSTENCILOP_DECRSAT

Decrement the stencil-buffer entry, clamping to zero.

D3DSTENCILOP_INVERT

Invert the bits in the stencil-buffer entry.

D3DSTENCILOP_INCR

Increment the stencil-buffer entry, wrapping to zero if the new value exceeds the maximum value.

D3DSTENCILOP_DECR

Decrement the stencil-buffer entry, wrapping to the maximum value if the new value is less than zero.

D3DSTENCILOP_FORCE_DWORD

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.

Remarks

Stencil-buffer entries are integer values ranging from 0 through 2ⁿ - 1, where n is the bit depth of the stencil buffer.
