Texture2D::GatherGreen(S,float,int) function

For four texel values that would be used in a bi-linear filtering operation, returns a comparison of their green component against a compare value.

Syntax

TemplateType GatherGreen(
  in sampler s,
  in float2 location,
  in int2 offset
);

s [in]

Type: sampler

The zero-based sampler index.

location [in]

Type: float2

The sample coordinates (u,v).

offset [in]

Type: int2

An offset that is applied to the texture coordinate before sampling.

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
x	x	x	x	x	x
