Possible to modify the size and background-color of ROI labels displayed?

[Emmanuel Levy]

Hello,

I found that naming a ROI (e,g. roiManager("Rename", "newName");)

and subsequently displaying its name (image -> overlay -> overlay
options -> show names) is very helpful to annotate images in a non
destructive manner.

However, the ROI labels are alway black on a cyan background. Ideally
I would like to have white labels and no background at all. Is this
possible? If it was possible to tune their aspect/ratio relative to
the size of the image it would also be great.

Thanks for any hint,

Emmanuel
