[s]I discovered that the unit of measure of the point xy is the decimeter.[/s]

i have found that deltax=1 corrispond 1=100micrometres

you could do so to be able to save changes to the default settings? eg if I set sigma = 2.4 then I should be able to save the change that I would see when I press the reset.

enter the rulers in centimeters or decimetres for both x and y thanks

I'd like to have the possibility to set the height of the work area, not just the scale with a slider that starts from 1 centimeter up to 20 centimeters

the program is almost ready ;D
