DeleteWindow(Int32,DicomSetImageFlags) Method
Summary
Deletes all the elements that describe "window center" and "window width".
Syntax
public void DeleteWindow(int frameIndex,Leadtools.Dicom.DicomSetImageFlags flags)
Public Overloads Sub DeleteWindow( _ByVal frameIndex As Integer, _ByVal flags As Leadtools.Dicom.DicomSetImageFlags _)
public void DeleteWindow(int frameIndex,Leadtools.Dicom.DicomSetImageFlags flags)
public void deleteWindow(int frameIndex, int dicomSetImageFlags) function Leadtools.Dicom.DicomDataSet.DeleteWindow(Int32,DicomSetImageFlags)(frameIndex ,flags)
public:void DeleteWindow(int frameIndex,Leadtools.Dicom.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
Remarks
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.
