HDICOMDS hDS;	a DICOM handle
pDICOMELEMENT pGraphicAnnSQItem;	pointer to a DICOMELEMENT structure
L_UINT uTextObjectIndex;	text annotation object index
pDICOMTEXTOBJECT pTextObject;	pointer to the text annotation object attributes structure

Updates the attributes of a text annotation object.

Parameter	Description
hDS	A DICOM handle.
pGraphicAnnSQItem	Pointer to an item element under the "Graphic Annotation Sequence" (0008,1115) in the "Graphic Annotation Module".
uTextObjectIndex	Index of the text annotation object to be updated
pTextObject	Structure containing the text annotation object attributes.

Returns

DICOM_SUCCESS	The function was successful.
>0	An error occurred. Refer to Return Codes.

Comments
