Hollow 2d markups in slice views

Support

Hi, I understand support for 2D operations is limited due to this platform being mostly used for 3D tasks. However, I am developing a python extension that requires key point placement in single slice views, for which I would prefer the markup control point glyphs show as rings. I have a couple of questions:

  • Has anyone had any success with showing markups in slice view without fill (circle2D, Square2D)
  • If this is not possible, can anyone recommend an approach to developing a custom markup to serve this purpose?

Thanks,
I would appreciate any help or similar experiences anyone can offer

Currently, control point glyph filling is not controllable independently because filling it is used as a hint when fiducial projection is enabled (filling indicates if the point is in front of or behind the current slice).

You can use Cross2D, StarBurst2D, CrossDot2D glyphs that do not occlude the center.

Thanks for your quick reply. I have added a switcher in my module to toggle between CrossDot2D and “circle” glyphs, which I am showing by programatically shifting the control points behind the slice view and showing their projections in slice view with ‘outline behind slice pane’ enabled (Using the Circle2D glyph type).

While this brings a new challenge when moving to 3d space and forces a fill on the circles while dragging them, it is sufficient for my requirement.

Thanks for your assistance and eager support for those using your software :slight_smile:
Cheers.
