LDicomDS::OnConvertLEADAnnObjToDicomAnnObj

Summary

Called for each DICOM annotation object generated by LDicomDS::ConvertLEADAnnObjToDicomAnnObjs.

Syntax

#include "Ltdic.h"

virtual L_UINT16 LDicomDS::OnConvertLEADAnnObjToDicomAnnObj(pGraphicObject, pTextObject)

Parameters

const pDICOMGRAPHICOBJECT pGraphicObject

Pointer to a DICOMGRAPHICOBJECT structure, which will hold the attributes of the generated DICOM graphic annotation object. If set to NULL, then the resulting object is a DICOM text annotation and in this case pTextObject cannot be NULL.

const pDICOMTEXTOBJECT pTextObject

Pointer to a DICOMTEXTOBJECT structure, which will hold the attributes of the generated DICOM text annotation object. If set to NULL then the resulting object is a DICOM graphic annotation and in this case pGraphicObject cannot be NULL.

Returns

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

Comments

As a result of calling LDicomDS::ConvertLEADAnnObjToDicomAnnObjs one or more DICOM annotation objects will be generated. For each of the resulting objects this overridable virtual function will get called once. If the resulting object is a "Graphic Object", then the parameter pGraphicObject will point to a DICOMGRAPHICOBJECT structure, which describes the new object, and in this case pTextObject will be set to NULL.

If the resulting object is a "Text Object", then the parameter pTextObject will point to a DICOMTEXTOBJECT structure, which describes the new object, and in this case pGraphicObject will be set to NULL. Suppose that a LEAD annotation object will get converted into two DICOM graphic objects and one DICOM text object. This means that this function will get called three times, it will be called twice with pGraphicObject != NULL and pTextObject == NULL and will be called once with pGraphicObject == NULL and pTextObject != NULL.

pTextObject and pGraphicObject cannot both be valid or both be NULL at the same time.

The implementation of the LDicomDS class for the function OnConvertLEADAnnObjToDicomAnnObj simply returns DICOM_SUCCESS. In order to make use of this callback function, you should create a new class derived from the LDicomDS class and override the function OnConvertLEADAnnObjToDicomAnnObj, providing the desired implementation.
