- frameIndex
- A zero-based index that identifies the frame number of in the dataset. If the dataset does not support Multi-frames, this parameter is ignored.
- flags
- determines how the modality LUT is deleted

Parameters
- frameIndex
- A zero-based index that identifies the frame number of in the dataset. If the dataset does not support Multi-frames, this parameter is ignored.
- flags
- determines how the modality LUT is deleted
Example
For an example, refer to DicomDataSet.SetModalityLut(DicomModalityLutAttributes,Int32[]).
Remarks
This method will delete all the elements defined under the "Modality LUT Module".
If the DICOM dataset has a Multi-frame Functional Groups module, the Modality LUT information will be found in the Pixel Value Transformation Sequence. The Pixel Value Transformation Sequence will be under an item in either:
If the Pixel Value Transformation Sequence is found under the Per-frame Functional Groups Sequence, parameter uFrameIndex must be set to the correct frame number so that the proper Pixel Value Transformation Sequence is removed.
If the Pixel Value Transformation Sequence is found under the Shared Functional Groups Sequence, parameter uFrameIndex is ignored. However, the DicomSetImageFlags.MfgOverwriteShared flag must be included to remove the Pixel Value Transformation Sequence.
The specific elements deleted are shown below:
(0028,9145) Pixel Value Transformation Sequence child elements
Valid flags are DicomSetImageFlags.MfgOverwriteShared and DicomSetImageFlags.None. All other flags are ignored. For a detailed discussion on Multi-frame Functional Groups see the topic Multi-frame Functional Groups.
