L_UINT16 LDicomDS::GetTextObjectInfo(pGraphicAnnSQItem, uTextObjectIndex, pTextObject, uStructSize)

pDICOMELEMENT pGraphicAnnSQItem;	/* pointer to a DICOMELEMENT structure */
L_UINT uTextObjectIndex;	/* text annotation object index */
pDICOMTEXTOBJECT pTextObject;	/* pointer to the text annotation object attributes structure to be updated */
L_UINT uStructSize;	/* the size of the DICOMTEXTOBJECT structure */

Gets 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	The index of the text annotation object whose attributes we want to retrieve.
pTextObject	Pointer to a structure which will be filled with the text annotation object attributes.
uStructSize	Size of the DICOMTEXTOBJECT structure. Pass sizeof(DICOMTEXTOBJECT).

Returns

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

Comments

This function will retrieve the attributes of a text object and store their values in the structure pointed to by pTextObject. pTextObject->uStructSize will be set to the value of the parameter uStructSize.
