L_UINT16 LDicomDS::DeleteModalityLUT(uFrameIndex, uFlags)
L_UINT32 uFrameIndex; |
/* index value */ |
L_UINT uFlags; |
/* reserved for future use */ |
Deletes all the elements that describe the Modality LUT.
Parameter |
Description |
uFrameIndex |
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. |
uFlags |
Default is 0. |
Returns
0 |
The function was successful. |
> 0 |
An error occurred. Refer to Return Codes. |
Comments
This function 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:
(5200,9229) Shared Functional Groups Sequence
(5200,9230) Per-frame Functional Groups Sequence
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 DICOM_SETIMAGE_MFG_OVERWRITE_SHARED flag must be included to remove the Pixel Value Transformation Sequence.
The specific elements deleted are shown below:

Rescale Intercept |
(0028,1053) |
Rescale Slope |
(0028,1054) |
