Texture2DArray::GatherBlue(S,float,int) function

Returns the blue components of the four texel values that would be used in a bi-linear filtering operation.

Syntax

TemplateType GatherBlue(
  in sampler s,
  in float3 location,
  in int2 offset
);

Parameters

s [in]

Type: sampler

The zero-based sampler index.

location [in]

Type: float3

The sample coordinates (u,v).

offset [in]

Type: int2

An offset that is applied to the texture coordinate 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.

This function is supported for the following types of shaders:
