Hi
I need for help to programming ENVI.
I want only read some points (x,y,DN) from some images opened in ENVI.
I'am trying with DISP_GET_LOCATION but I cant display image and the
function DISP_GET_LOCATION gives me (x,y) of the last point I have
click!
How can I do it?
thanks
Roberto

You probably need to write a user-defined move/motion routine. Look at the
ENVI Programmer's Guide ("progguid.pdf") documentation manual included with
the installation. The "Interactive User Routines" chapter has a section on
"User Move Routines".
