'Usage

Dim instance As DicomDataSet
Dim frameIndex As Integer
Dim flags As DicomSetImageFlags
 
instance.DeleteWindow(frameIndex, flags)

public void DeleteWindow( 
   int frameIndex,
   DicomSetImageFlags flags

public void deleteWindow(int frameIndex, int dicomSetImageFlags)

 function Leadtools.Dicom.DicomDataSet.DeleteWindow(Int32,DicomSetImageFlags)( 
   frameIndex ,
   flags 
)

public:
void DeleteWindow( 
   int frameIndex,
   DicomSetImageFlags flags
)

Parameters

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

This method will delete the following elements:

Window Center (0028,1050)

Window Width (0028,1051)

Window Center and Width Explanation (0028,1055)

If the DICOM dataset has a Multi-frame Functional Groups module, the Window information will be found in the Frame VOI LUT Sequence. The Frame VOI LUT Sequencewill be under an item in either:

(5200,9229) Shared Functional Groups Sequence
(5200,9230) Per-frame Functional Groups Sequence

If the Frame VOI LUT Sequence is found under the Per-frame Functional Groups Sequence, parameter uFrameIndex must be set to the correct frame number so that the proper Frame VOI LUT Sequence is removed.

If the Frame VOI LUT Sequence is found under the Shared Functional Groups Sequence, parameter uFrameIndex is ignored. However, the DicomSetImageFlags.MfgOverwriteShared flag must be included to remove the Frame VOI LUT Sequence.
The specific elements deleted are shown below:

(0028,9132) Frame VOI LUT Sequence Child Elements

Tag	Name
(0028,1050)	Window Center
(0028,1051)	Window Width
(0028,1055)	Window Center & Width Explanation

Valid flags are DicomSetImageFlags.None and DicomSetImageFlags.MfgOverwriteShared. All other flags are ignored. For a detailed discussion on Multi-frame Functional Groups see the topic Multi-frame Functional Groups.

For an example, refer to SetWindow.
