For four texel values that would be used in a bi-linear filtering operation, returns a comparison of their red component against a compare value along with tile-mapping status.
TemplateType GatherCmpRed( in SamplerState S, in float Location, in float CompareValue, in int Offset, out uint Status );
The zero-based sampler index.
The sample coordinates (u,v).
A value to compare each against each sampled value.
The offset applied to the texture coordinates before sampling.
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.
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:
