Hi.
Does anyone know ... ?
If I do prefer calling IDL functions from my C routines, instead of
calling my C routines from IDL, could you please teach me how to do that
?
I was able to use "tv", but was never successful to use "tvscl".
I also need to grab the true image coordinates(image coordinates of a
pixel, in the original image size domain before image size scaling)
of the location of cursor (picked by mouse)
on the image displayed by "tvscl".
I heavily use matrix computation that is one of the reason why I
hesitate to use CALL_EXTERNAL.
Thanks in advance.

I do not understand why matrix computation might be a reason to use C
for calling idl. However, in idl distribution external/callable of unix
and VMS machines an example calltest.c given.
