LDicomDS::CreateLayer

Summary

Adds a new item under the "Graphic Layer Sequence" (0070,0060) in the Graphic Layer Module".

Syntax

#include "Ltdic.h"

L_UINT16 LDicomDS::CreateLayer(pGraphicLayer, pLayerIndex)

Parameters

pDICOMGRAPHICLAYER pGraphicLayer

Pointer to a Graphic Layer attributes structure, which holds the attributes of the layer to be created.

L_UINT * pLayerIndex

Pointer to a variable, which will be updated with the index of the newly created layer.

Returns

Value	Meaning
0	SUCCESS
>0	An error occurred. Refer to Return Codes.

Comments

Before calling this function, initialize pDICOMGRAPHICLAYER->uStructSize to be sizeof(DICOMGRAPHICLAYER) and initialize all the structure members.

If for example there are already 2 items under the "Graphic Layer Sequence" (0070,0060) and we call this function, then the index of the new layer will be 2.

This function will fail and return DICOM_ERROR_PARAMETER if a layer with the same name as the new layer already exists in the dataset.
