-
S [in]
-
Type: SamplerState
The zero-based sampler index.
-
Location [in]
-
Type: float
The sample coordinates (u,v).
-
Offset1 [in]
-
Type: int2
The first offset component applied to the texture coordinates before sampling.
-
Offset2 [in]
-
Type: int2
The second offset component applied to the texture coordinates before sampling.
-
Offset3 [in]
-
Type: int2
The third offset component applied to the texture coordinates before sampling.
-
Offset4 [in]
-
Type: int2
The fourth offset component applied to the texture coordinates before sampling.
-
Status [out]
-
Type: uint
The status of the operation. You can't access the status directly; instead, pass the status to the CheckAccessFullyMapped intrinsic function. CheckAccessFullyMapped returns TRUE if all values from the corresponding Sample, Gather, or Load operation accessed mapped tiles in a tiled resource. If any values were taken from an unmapped tile, CheckAccessFullyMapped returns FALSE.
Type: TemplateType
A four-component value whose type is the same as the template type.
The texture samples can be used for bilinear interpolation.
This function is supported for the following types of shaders:
Vertex | Hull | Domain | Geometry | Pixel | Compute |
