At this stage I'm trying to build an application that draw and manages ROI'
s, with some requirements but still trying to make it simple. My priorities
make that I'm trying to maximize the use of idl functions. And then when
finished, if I still have time for development then I make some functions of
my own. That was the reason why was making use of cw_defroi
(and I'm still trying)
Besides drawing, it should allow the user, to move and eventually resize,
and to save and load. I was thinking of making it through x and y indices.
I can "see" if the user presses the arrows and then affecting the indices.
For resizing, checking if the user clicks the border and then .
I haven't think in the solution for all options. But for now it is clear
that if I want to manipulate the roi I need to get the indices in the (x,y)
form.
