pDICOMGRAPHICLAYER pGraphicLayer; |
/* pointer to a Graphic Layer attributes structure */ |
L_UINT * pLayerIndex; |
/* pointer to a variable, which will be updated with the index of the newly created layer.*/ |
Adds a new item under the "Graphic Layer Sequence" (0070,0060) in the Graphic Layer Module".
Parameter |
Description |
pGraphicLayer |
Pointer to a Graphic Layer attributes structure, which holds the attributes of the layer to be created. |
pLayerIndex |
Pointer to a variable, which will be updated with the index of the newly created layer. |
Returns
0 |
SUCCESS |
>0 |
An error occurred. Refer to Return Codes. |
Comments
Before calling this function, initialize pDICOMGRAPHICLAYER->uStructSize to be sizeof(DICOMGRAPHICLAYER) and initialize all the structure members.
If for example there are already 2 items under the "Graphic Layer Sequence" (0070,0060) and we call this function, then the index of the new layer will be 2.
This function will fail and return DICOM_ERROR_PARAMETER if a layer with the same name as the new layer already exists in the dataset.
