Problems with Slicermorph’s HiResScreenCapture module

3

Meeting notes

  • Discussed issue & improvements of @oothomas related to HiResScreenCapture module

    • Three approaches:

      1. Paraview-based approach - using a tile-based approach where the scene is rendered in multiple passes with different viewports
      2. offscreen rendering: Z-buffer was behaving differently, issue with text rendering
      3. Render Slicer view in a larger “window” - may cause issues with clipped window or inability to set sizes larger than the screen

    • Current effort are geared toward approach 3

      Experiment to make threeD view into a floating window:

      layoutManager = slicer.app.layoutManager()
currentLayout = layoutManager.layout
threeDWidget = layoutManager.threeDWidget(0)
threeDWidget.setParent(None)
threeDWidget.show()
threeDWidget.size = qt.QSize(5000, 5000)
print(threeDWidget.size)
threeDWidget.grab().save("/tmp/file.png")

# make sure the layout changes so that the threeDWidget is reparented and resized.
differentLayout = slicer.vtkMRMLLayoutNode.SlicerLayoutCustomView
assert differentLayout != currentLayout
layoutManager.layout = differentLayout
layoutManager.layout = currentLayout
  • Discussed the potential usefulness of a Python package that mocks 3D Slicer’s Python module for improved autocompletion in external editors like VSCode.
