L_LTDIC_API L_UINT16 L_DicomSetLayerInfo(hDS, uLayerIndex, pGraphicLayer)

Parameters

HDICOMDS hDS

A DICOM handle.

Zero-based index of the layer to be updated.

pDICOMGRAPHICLAYER pGraphicLayer

Structure containing the layer attributes.

Returns

Value	Meaning
DICOM_SUCCESS	The function was successful.

Comments

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

The index(uLayerIndex) is based on the number of items under the "Graphic Layer Sequence" (0070,0060), for example the index of the first item is zero.
