ROI

[uschifriedrich]

Hi
Sorry for this "stupid" question, but Im actually very uneducated in those kind of things.

My problem is: How do I Draw random points in only a ROI?

I use for example the macro "DrawRandomDots". the roplem: it draws in the whole picture!

Does anyone knows how to restrict the  dots to a ROI?

may I ask a more stupid question ~what is a ROI ? sorry I am a greener~
