#include "l_bitmap.h"

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

Retrieves the attributes of a layer at the specified index.

Parameters

HDICOMDS hDS

A DICOM handle.

L_UINT uLayerIndex

Zero-based index of the layer whose attributes are to be retrieved.

pDICOMGRAPHICLAYER pGraphicLayer

Pointer to a structure which will be filled with the layer attributes.

L_UINT uStructSize

Size of the DICOMGRAPHICLAYER structure. Pass sizeof(DICOMGRAPHICLAYER).

Returns

Value Meaning
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.
