Hello David,
The first part of the code goes like this
Pro ChangeView, file1,file2,file3
argsarray=command_line_args(count=nparams)
if nparams eq 3 then begin
file1=argsarray[0]
file2=argsarray[1]
file3=argsarray[2]
endif
if (nparams lt 3) then begin
file1 = DIALOG_PICKFILE(title='Select the first image')
file2 = DIALOG_PICKFILE(title='Select the second image')
file3 = DIALOG_PICKFILE(title='Select the change image')
endif
img1= read_envi_img(file1,lines=lines, samples=samples, bands=bands)
.
.
.
and I try to execute it using
idl -vm=changeview.sav -args "c:\june" "c:\october" "c:\june_oct"
This one opens the dialog window which means it is not recognizing the
input arguments. Is there something wrong with my procedure definition
"Pro changeview, file1,file2,file3" ?
Thank you
Prashanth
