pydicom.pixels.apply_presentation_lut(arr: np.ndarray, ds: Dataset) → np.ndarray

Apply a Presentation LUT to arr and return the P-values.

Parameters:

• arr (numpy.ndarray) – The ndarray to apply the presentation LUT operation to.

• ds (dataset.Dataset) – A dataset containing Presentation LUT Module elements.

Returns:

If a Presentation LUT Module is present in ds then returns an array of P-values, otherwise returns arr unchanged.
