LDicomDS::CreateGraphicObject

#include "Ltdic.h"

L_UINT16 LDicomDS::CreateGraphicObject(pGraphicAnnSQItem, pGraphicObject, bCheckLayer)

Creates a new graphic annotation object.

Parameters

pDICOMELEMENT pGraphicAnnSQItem

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

pDICOMGRAPHICOBJECT pGraphicObject

Pointer to the graphic object attributes structure.

L_BOOL bCheckLayer

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

Value	Meaning
TRUE	Check if the layer exists before adding the object. If it does not exist, 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 pDICOMGRAPHICOBJECT->uStructSize to be sizeof(DICOMGRAPHICOBJECT) and initialize all the structure members.

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