Texture2DArray::GatherGreen(S,float,int2,int2,int2,int2) function
Returns the green components of the four texel values that would be used in a bi-linear filtering operation.
Syntax
TemplateType GatherGreen(
in SamplerState S,
in float3 Location,
in int2 Offset1,
in int2 Offset2,
in int2 Offset3,
in int2 Offset4
);
Parameters
-
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.
Return value
Type: TemplateType
A four-component value whose type is the same as the template type.
Remarks
The texture samples can be used for bilinear interpolation.
