stepping through with debugger:

  • the three channel images are created correctly
  • the crash happens when its trying to harmonize the original leaf Dataset from the ImagePlus modified by the plugin
  • somehow the original ImagePlus has c,z,t == 1 and a completely empty stack.
  • plugin code does not look like it deletes slices.
  • plugin calls updateAndDraw(). This might cause harmonization while plugin is active (only preharm done up to that point) and the ImagePlus has already been locked.

more debugging:

  • RGBStackSplitter does indeed deleteSlice() from original image unless alt key down. - Putting alt key down does not fix it in IJ2. Do we need to send setKeyDown() and setKeyUp() events to IJ from our keyboard events to support alt and shift and other things that IJ1 can react to. I think so.

In 2ea5999118fe7ce2f7851645dae7bf80d1451089 I added event code to LegacyManager to make sure IJ1 knows status of ALT, SHIFT, CONTROL, and SPACE. Running the split channels with ALT key down runs to completion successfully.

Now in the legacy layer need to handle case where the ImagePlus has been emptied out by IJ1.
