LDicomDS::CreateTextObject

#include "Ltdic.h"

L_UINT16 LDicomDS::CreateTextObject(pGraphicAnnSQItem, pTextObject, bCheckLayer=FALSE)

Creates a new text annotation object.

Parameters

pDICOMELEMENT pGraphicAnnSQItem

Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module".

pDICOMTEXTOBJECT pTextObject

Pointer to the text object attributes structure.

L_BOOL bCheckLayer

Flag that indicates whether to verify that the layer (to which the text object will be added) exists or not.

Value Meaning
TRUE Check if the layer exists before adding the object. If it does not existed, then return an error.
FALSE Add the new object without checking the existence of the layer.

Returns

Value Meaning
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.

When the parameter bCheckLayer is set to TRUE, then the function checks if the layer specified in the member variable pszLayerName exists or not. If it does not exist, an error will be returned.
