L_LTDIC_API L_UINT16 L_DicomGetTextObjectInfo(hDS, pGraphicAnnSQItem, uTextObjectIndex, pTextObject, uStructSize)

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 to be updated

L_UINT uStructSize;

the size of the DICOMTEXTOBJECT structure - pass sizeof(DICOMTEXTOBJECT)

Gets 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

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

DICOM_SUCCESS

The function was successful.

>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.
