#include "Ltdic.h"

L_UINT16 LDicomDS::SetTextObjectInfo(pGraphicAnnSQItem, uTextObjectIndex, pTextObject)

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
pGraphicAnnSQItem	Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module".
uTextObjectIndex	Index of the text annotation object to be updated
pTextObject	Structure containing the text annotation object attributes.

Returns

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

Comments

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