HDICOMDS hDS; |
a DICOM handle |
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 - pass sizeof(DICOMGRAPHICOBJECT) |
Gets the attributes of the specified graphic annotation object.
Parameter |
Description |
hDS |
A DICOM handle. |
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). |
DICOM_SUCCESS |
The function was successful. |
>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 L_DicomGetGraphicObjPointsCount in order to get the "Number of Graphic Points" (0070,0021) in this object and allocate pGraphicObject->pAnnPoints accordingly.
