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.
