Summary

Removes all layers under the "Graphic Layer Module".

Syntax

Parameters

annSequence
true to remove the items, under the "Graphic Annotation Sequence", that reference the layers; false to remove only the layers.

Example

using Leadtools; using Leadtools.Dicom; public void DicomLayerSample() { //Make sure to initialize the DICOM engine, this needs to be done only once //In the whole application DicomEngine.Startup(); using (DicomDataSet dicomDataset = new DicomDataSet()) { // We can also initialize in here the "Grayscale Softcopy Presentation State" class dicomDataset.Initialize(DicomClassType.Undefined, DicomDataSetInitializeType.ExplicitVRLittleEndian); //We can remove individual layers by calling RemoveLayerByIndex and RemoveLayerByName dicomDataset.RemoveAllLayers(true); DicomGraphicLayer graphicLayer = new DicomGraphicLayer(); graphicLayer.LayerOrder = 1; graphicLayer.LayerDescription = "First Layer"; graphicLayer.LayerName = "LAYER0"; graphicLayer.Grayscale = 0; graphicLayer.RgbLayerColor[0] = 255; dicomDataset.CreateLayer(graphicLayer); Debug.Assert(dicomDataset.GetLayerIndex("LAYER0") == 0); DicomGraphicLayer graphicLayer1 = dicomDataset.GetLayerInformation(0); Debug.Assert(graphicLayer1 != null); Debug.Assert(graphicLayer1.LayerOrder == 1); graphicLayer.LayerName = "LAYER1"; dicomDataset.SetLayerInformation(0, graphicLayer); Debug.Assert(dicomDataset.LayerCount == 1); // We can also call GetLayerElementByName to get the layer element DicomElement layer = dicomDataset.GetLayerElementByIndex(0); Debug.Assert(layer != null); dicomDataset.RemoveLayerGraphicObjects(layer); Debug.Assert(dicomDataset.GetLayerGraphicObjectCount(layer) == 0); dicomDataset.RemoveLayerTextObjects(layer); Debug.Assert(dicomDataset.GetLayerTextObjectCount(layer) == 0); dicomDataset.Save(Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "PresentationState.dcm"), DicomDataSetSaveFlags.None); } DicomEngine.Shutdown(); } static class LEAD_VARS { public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; }
