#include "Ltdic.h"

L_UINT16 LDicomDS::SetGraphicObjectInfo(pGraphicAnnSQItem, uGraphicObjectIndex, pGraphicObject)

pDICOMELEMENT pGraphicAnnSQItem;	/* pointer to a DICOMELEMENT structure */
L_UINT uGraphicObjectIndex;	/* graphic annotation object index */
pDICOMGRAPHICOBJECT pGraphicObject;	/* pointer to the graphic annotation object attributes structure */

Updates the attributes of a graphic annotation object.

Parameter	Description
pGraphicAnnSQItem	Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module".
uGraphicObjectIndex	Index of the graphic annotation object to be updated
pGraphicObject	Structure containing the graphic annotation object attributes.

Returns

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

Comments

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