I am not being able to change de slice views background colors. I am doing this:
viewNode = slicer.app.layoutManager().sliceWidget('Red').mrmlSliceNode()
viewNode.SetBackgroundColor(1,1,1)
viewNode.SetBackgroundColor2(1,1,1)
But it has no effect. What should I do? I want to change to white. Thank you!
Try:
view = slicer.app.layoutManager().sliceWidget('Red').sliceView() view.setBackgroundColor(qt.QColor.fromRgbF(1,1,1))
@jumbojing you forgot to add view.forceRender() to apply the modifications
For all slice view we can write like
layoutManager = slicer.app.layoutManager()
for sliceViewName in layoutManager.sliceViewNames():
view = layoutManager.sliceWidget(sliceViewName).sliceView()
view.setBackgroundColor(qt.QColor.fromRgbF(1,1,1))
view.forceRender()
@Dwij_Mistry Perfect! Thanks 
但是, 如果每个slice有个边框就更好了
However, it would be better if each slice had a balck border.
If you are ok to use dark mode of slicer then we can get border which is nothing but a background color of central widget of MainWindow
Dark mode can be activated from Menu → Edit → application settings → appearance → style → dark slicer
Finally I found a way by which we can have border without changing the slicer color mode.
def paint_border(view):
color = [0.0, 0.0, 0.0] #change color for border
lineThickness = 10.0
viewRenderer = view.renderWindow().GetRenderers().GetItemAsObject(0)
borderPoints = vtk.vtkPoints()
borderPoints.InsertNextPoint( 1e-4, 1e-4, 0)
borderPoints.InsertNextPoint(0.9999, 1e-4, 0)
borderPoints.InsertNextPoint(0.9999, 0.9999, 0)
borderPoints.InsertNextPoint( 1e-4, 0.9999, 0)
borderCells = vtk.vtkCellArray()
borderCells.InsertNextCell(5)
for i in range(5):
borderCells.InsertCellPoint(i%5)
borderPolyData = vtk.vtkPolyData()
borderPolyData.SetPoints(borderPoints)
borderPolyData.SetLines(borderCells)
borderCoordinate = vtk.vtkCoordinate()
borderCoordinate.SetCoordinateSystemToNormalizedViewport()
borderCoordinate.SetViewport(viewRenderer)
borderPolyDataMapper = vtk.vtkPolyDataMapper2D()
borderPolyDataMapper.SetInputData(borderPolyData)
borderPolyDataMapper.SetTransformCoordinate(borderCoordinate)
borderPolyDataMapper.SetTransformCoordinateUseDouble(True)
highlightedBorderActor = vtk.vtkActor2D()
highlightedBorderActor.SetMapper(borderPolyDataMapper)
highlightedBorderActor.GetProperty().SetColor(color[0], color[1], color[2])
highlightedBorderActor.GetProperty().SetDisplayLocationToForeground()
highlightedBorderActor.GetProperty().SetLineWidth(lineThickness)
viewRenderer.AddActor2D(highlightedBorderActor)
view.renderWindow().Render()
#calling
paint_border(slicer.app.layoutManager().threeDWidget(0).threeDView())
for sliceViewName in slicer.app.layoutManager().sliceViewNames():
paint_border(slicer.app.layoutManager().sliceWidget(sliceViewName).sliceView())
OutPut
I am also facing the same issue, Can any one please share why it is happening? or any alternative solution?
I cannot reproduce this, so I cannot tell what’s wrong, but maybe you need to tweak the 1e-4 and 0.9999 constants.
