Example
using Leadtools;
using Leadtools.Dicom;
public void TestOverlay()
{
string dicomFileName = Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "Overlay.dcm");
//Make sure to initialize the DICOM engine, this needs to be done only once
//In the whole application
DicomEngine.Startup();
using (DicomDataSet ds = new DicomDataSet())
{
//Load DICOM File
ds.Load(dicomFileName, DicomDataSetLoadFlags.None);
if (ds.OverlayCount > 0)
{
RasterOverlayAttributes attributes = ds.GetOverlayAttributes(0);
if (attributes != null)
{
// We can call in here methods like GetOverlayGroupNumber, IsOverlayInDataset
// and GetOverlayActivationLayer to get some further infromation about the overlay
//Let's get the overlay Image, If RasterOverlayAttributes.NumFramesInOverlay
//Is greater than 1 we can call GetOverlayImages to extract all the frames
RasterImage overlayImage = ds.GetOverlayImage(0);
if (overlayImage != null)
{
using (DicomDataSet ds1 = new DicomDataSet())
{
ds1.Initialize(DicomClassType.DXImageStoragePresentation, DicomDataSetInitializeType.ExplicitVRLittleEndian);
ds1.SetOverlayAttributes(0, attributes, DicomSetOverlayFlags.None);
ds1.SetOverlayImage(0, overlayImage);//We can call SetOverlayImages if the overlay has more than one frame
ds1.Save(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "NewOverlay.dcm"), DicomDataSetSaveFlags.None);
}
}
}
}
}
