```

### Members

*Filter*\
Type: D3D12\_FILTER

A [D3D12\_FILTER](/reference/graphics/d3d12/enums/d3d12_filter_public)-typed value that specifies the filtering method to use when sampling a texture.

*AddressU*\
Type: D3D12\_TEXTURE\_ADDRESS\_MODE

A [D3D12\_TEXTURE\_ADDRESS\_MODE](/reference/graphics/d3d12_x/enums/d3d12_texture_address_mode)-typed value that specifies the method to use for resolving a u texture coordinate that is outside the 0 to 1 range.

*AddressV*\
Type: D3D12\_TEXTURE\_ADDRESS\_MODE

A [D3D12\_TEXTURE\_ADDRESS\_MODE](/reference/graphics/d3d12_x/enums/d3d12_texture_address_mode)-typed value that specifies the method to use for resolving a v texture coordinate that is outside the 0 to 1 range.

*AddressW*\
Type: D3D12\_TEXTURE\_ADDRESS\_MODE

A [D3D12\_TEXTURE\_ADDRESS\_MODE](/reference/graphics/d3d12_x/enums/d3d12_texture_address_mode)-typed value that specifies the method to use for resolving a w texture coordinate that is outside the 0 to 1 range.

*MipLODBias*\
Type: FLOAT

Offset from the calculated mipmap level. For example, if the runtime calculates that a texture should be sampled at mipmap level 3 and **MipLODBias** is 2, the texture will be sampled at mipmap level 5.

*MaxAnisotropy*\
Type: UINT

Clamping value used if **D3D12\_FILTER\_ANISOTROPIC** or **D3D12\_FILTER\_COMPARISON\_ANISOTROPIC** is specified in **Filter**. Valid values are between 1 and 16.

*ComparisonFunc*\
Type: D3D12\_COMPARISON\_FUNC

A [D3D12\_COMPARISON\_FUNC](/reference/graphics/d3d12/enums/d3d12_comparison_func_public)-typed value that specifies a function that compares sampled data against existing sampled data.

*BorderColor*\
Type: FLOAT\[4]

RGBA border color to use if [D3D12\_TEXTURE\_ADDRESS\_MODE\_BORDER](/reference/graphics/d3d12_x/enums/d3d12_texture_address_mode) is specified for **AddressU**, **AddressV**, or **AddressW**. Range must be between 0.0 and 1.0 inclusive.

*MinLOD*\
Type: FLOAT

Lower end of the mipmap range to clamp access to, where 0 is the largest and most detailed mipmap level and any level higher than that is less detailed.

*MaxLOD*\
Type: FLOAT

Upper end of the mipmap range to clamp access to, where 0 is the largest and most detailed mipmap level and any level higher than that is less detailed. This value must be greater than or equal to **MinLOD**. To have no upper limit on LOD, set this member to a large value.
