#include "Ltdic.h"
L_UINT16 LDicomDS::GetGraphicObjectInfo(pGraphicAnnSQItem, uGraphicObjectIndex, pGraphicObject, uStructSize)
Gets the attributes of the specified graphic annotation object.
Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module".
The index of the graphic annotation object whose attributes we want to retrieve.
Pointer to a structure which will be filled with the graphic annotation object attributes.
Size of the DICOMGRAPHICOBJECT structure. Pass sizeof(DICOMGRAPHICOBJECT).
Value | Meaning |
---|---|
0 | SUCCESS |
>0 | An error occurred. Refer to Return Codes. |
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.
