L_UINT16 LDicomDS::CreateGraphicObject(pGraphicAnnSQItem, pGraphicObject, bCheckLayer)
pDICOMELEMENT pGraphicAnnSQItem; |
/* pointer to a DICOMELEMENT structure */ |
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 */ |
Creates a new graphic annotation object.
Parameter |
Description |
|
pGraphicAnnSQItem |
Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module". |
|
pGraphicObject |
Pointer to the graphic object attributes structure. |
|
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
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.
