Samples a texture on mipmap level 0 only and compares the result to a comparison value. Returns status about the operation.
DXGI_FORMAT SampleCmpLevelZero( in SamplerState S, in float Location, in float CompareValue, out uint Status );
A Sampler state. This is an object declared in an effect file that contains state assignments.
The texture coordinates. The argument type is dependent on the texture-object type.
Texture-Object Type Parameter Type Texture1D float Texture1DArray, Texture2D float2 Texture2DArray, Texture3D, TextureCube float3 TextureCubeArray float4
A floating-point value to use as a comparison value.
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.
The texture format, which is one of the typed values listed in DXGI_FORMAT.
