LDicomDS::DeleteWindow

#include "ltdic.h"

L_UINT16 LDicomDS::DeleteWindow(uFrameIndex, uFlags)

Deletes all the elements that describe window center and window width.

Returns

Comments

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
