Leadtools.Dicom Namespace > DicomDataSet Class : GetOverlayAttributes Method |
public RasterOverlayAttributes GetOverlayAttributes( int index )
'Declaration
Public Function GetOverlayAttributes( _ ByVal index As Integer _ ) As RasterOverlayAttributes
'Usage
Dim instance As DicomDataSet Dim index As Integer Dim value As RasterOverlayAttributes value = instance.GetOverlayAttributes(index)
public RasterOverlayAttributes GetOverlayAttributes( int index )
public RasterOverlayAttributes getOverlayAttributes(int index)
function Leadtools.Dicom.DicomDataSet.GetOverlayAttributes( index )
public: RasterOverlayAttributes^ GetOverlayAttributes( int index )
If the overlay data is embedded in the "Image Pixel Data" (7FE0,0010), UseBitPlane will be set to true. If UseBitPlane is false, then the overlay data is stored in the "Overlay Data" (60xx,3000) element and in this case you can call GetOverlayImage to get the data for that overlay.
Origin will hold the value of the "Overlay Origin" (60xx,0050) element; however, the upper left pixel of the image will have the coordinate 0\0, instead of 1\1 (as in the DICOM standard).
This method will always set Color to black.
For multi-frame overlays, this method will update FramesInOverlay with the value of "Number of Frames in Overlay" (60xx,0015) element and ImageFrameOrigin with the value of "Image Frame Origin" (60xx,0051) element.
ActivationLayer will be updated with the value of the element "Overlay Activation Layer" (60xx,1001).
