L_DicomGetLayerInfo

#include "l_bitmap.h"

L_LTDIC_API L_UINT16 L_DicomGetLayerInfo(hDS, uLayerIndex, pGraphicLayer, uStructSize)

HDICOMDS hDS;	a DICOM handle
L_UINT uLayerIndex;	zero-based index of the layer
pDICOMGRAPHICLAYER pGraphicLayer;	pointer to a DICOMGRAPHICLAYER structure
L_UINT uStructSize;	the size of the DICOMGRAPHICLAYER structure - pass sizeof(DICOMGRAPHICLAYER)

Retrieves the attributes of a layer at the specified index.

Parameter	Description
hDS	A DICOM handle.
uLayerIndex	Zero-based index of the layer whose attributes are to be retrieved.
pGraphicLayer	Pointer to a structure which will be filled with the layer attributes.
uStructSize	Size of the DICOMGRAPHICLAYER structure. Pass sizeof(DICOMGRAPHICLAYER).

Returns

DICOM_SUCCESS	The function was successful.
>0	An error occurred. Refer to Return Codes.

Comments

This function will retrieve the attributes of a layer and store their values in the structure pointed to by pGraphicLayer.

pGraphicLayer->uStructSize will be set to the value of the parameter uStructSize.

The members of the structure pGraphicLayer are based on the "Graphic Layer Module Attributes" in the DICOM standard.

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.
