I am want to use the overlay to mark a single pixel in an image that has been zoomed to show individual pixels - within a macro.

But I cannot see how to mark a single pixel in the overlay.
Overlay.drawRect   marks an area of 2x2 pixels centred on my target pixel but 1x1
Overlay.drawLine  with the two positions set the same, marks a single pixel offset

I can mark a single pixel using the ROI manager and then move it and convert it to an overlay, but this seems unduly cumbersome, is there a better way of marking single pixels in a overlay ?
