Parameters
_Address_mode
The address mode to use to sample the texture_view. The address mode is the same for all dimensions._Sampler
The sampler configuration to use to sample the texture_view._Coord
The coordinates to take the sample from. Fractional coordinate values are used to interpolate between sample texels.
Return Value
A rank 4 short vector containing the red (x) component of the 4 sampled texel values.
