D3D12DDI_STENCIL_OP enumeration

Description

The D3D12DDI_STENCIL_OP enumeration type contains values that identify operations on stencil buffers in a call to the driver's CreateDepthStencilState function.

Constants

`D3D12DDI_STENCIL_OP_KEEP`

Do not update the entry in the stencil buffer. D3D12DDI_STENCIL_OP_KEEP is the default value.

`D3D12DDI_STENCIL_OP_ZERO`

Set the stencil-buffer entry to 0.

`D3D12DDI_STENCIL_OP_REPLACE`

Replace the stencil-buffer entry with a reference value.

`D3D12DDI_STENCIL_OP_INCR_SAT`

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

`D3D12DDI_STENCIL_OP_DECR_SAT`

Decrement the stencil-buffer entry, clamping to zero.

`D3D12DDI_STENCIL_OP_INVERT`

Invert the bits in the stencil-buffer entry.

`D3D12DDI_STENCIL_OP_INCR`

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

`D3D12DDI_STENCIL_OP_DECR`

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