Deletes all the elements that describe window center and window width.
L_UINT16 LDicomDS::DeleteWindow(uFrameIndex, uFlags)
A zero-based index that identifies the frame number in the dataset. If the dataset does not support Multi-frames, this parameter is ignored.
|DICOM_SETIMAGE_MFG_OVERWRITE_SHARED||[0x008] If set, existing Frame VOI LUT Sequence items under the Shared Functional Groups Sequence will be deleted. If this flag is not included, Shared Functional Groups Sequence elements are unchanged.|
|0||The function was successful.|
|> 0||An error occurred. Refer to Return Codes.|
This function will delete the following elements:
Window Center (0028,1050)
Window Width (0028,1051)
Window Center & 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 Sequence will 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 DICOM_SETIMAGE_MFG_OVERWRITE_SHARED 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
