LDicomDS::GetGraphicObjectInfo

#include "Ltdic.h"

L_UINT16 LDicomDS::GetGraphicObjectInfo(pGraphicAnnSQItem, uGraphicObjectIndex, pGraphicObject, uStructSize)

pDICOMELEMENT pGraphicAnnSQItem;

pointer to a DICOMELEMENTstructure

L_UINT uGraphicObjectIndex;

graphic annotation object index

pDICOMGRAPHICOBJECT pGraphicObject;

pointer to the graphic annotation object attributes structure to be updated

L_UINT uStructSize;

the size of the DICOMGRAPHICOBJECT structure

Gets the attributes of the specified graphic annotation object.

Parameter

Description

pGraphicAnnSQItem

Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module".

uGraphicObjectIndex

The index of the graphic annotation object whose attributes we want to retrieve.

pGraphicObject

Pointer to a structure which will be filled with the graphic annotation object attributes.

uStructSize

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

Returns

0

SUCCESS

>0

An error occurred. Refer to Return Codes.

Comments

This function will retrieve the attributes of the specified graphic object and store their values in the structure pointed to by pGraphicObject.

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

Before calling this function you can call LDicomDS::GetGraphicObjPointsCount in order to get the "Number of Graphic Points" (0070,0021) in this object and allocate pGraphicObject->pAnnPoints accordingly.
