Obtain pixel location instead of RAS using Markups

Support

I would like to be able to use the Markups module to obtain a 2D pixel location, instead of the RAS coordinates on a transformed image.
For example I would like to obtain the coordinates of Image_Probe not RAS in the following image:

Any help is appreciated. Thanks.

As shown in

https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Get_DataProbe_text

you can do something like

infoWidget = slicer.modules.DataProbeInstance.infoWidget
infoWidget.layerIJKs['B'].text

I’ve added an example to the script repository that shows how to get voxel coordinate from RAS coordinate of a markup fiducial point: https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Get_volume_voxel_coordinates_from_markup_fiducial_RAS_coordinates
