L_DicomCopyDS

#include "ltdic.h"

L_LTDIC_API L_UINT16 L_DicomCopyDS(hDstDS, pDstParent, hSrcDS, pSrcParent)

Copies the data elements from one data set to another.

Returns

Comments

If both pSrcParent and pDstParent are NULL, the source data set will be inserted at the root level of the destination data set. Therefore the highest level elements of the source data set will be added as siblings to the highest level elements of the destination data set. This can be seen in the diagram below.

If pSrcParent is not NULL and pDstParent is NULL, the children of pSrcParent will be added at the root level of the destination data set (i.e. as siblings to elements at the highest level). This can be seen in the diagram below. Note that the source elements to be added are in blue.

If pScrParent is NULL and pDstParent is not NULL, the entire source data set will be added as children to pDstParent. This can be seen in the diagram below.

If pSrcParent and pDstParent are both not NULL, then the children of pSrcParent are added as the children of pDstParent. This can be seen in the diagram below. The original children of pDstParent are in red and the source elements to be added are in blue.

If an inserted element has the same tag value as a destination element at the same level and with the same parent, then the value from the source element is copied into the destination element and any child elements are added accordingly. For example, the diagram below shows the result of a call to L_DicomCopyDS. If the two elements indicated by the arrows have the same tag value, the value from the source element is copied into the destination element and the structure on the right results. This is shown by the red outline of the destination element with the blue center of the source element.

To make the destination data set an exact copy of the source data set, instead of inserting it within the destination data set, you must call L_DicomResetDS with the destination data set as the parameter, before calling L_DicomCopyDS.
