#3552: i.spectral fails due to missing monitor
-------------------------+-------------------------
Reporter: marisn | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.6.0
Component: Imagery | Version: svn-trunk
Keywords: i.spectral | CPU: Unspecified
Platform: Unspecified |
-------------------------+-------------------------
From the code of i.spectral I could not figure out what should happen when
gnuplot is absent – should it plot on screen? Into a file?
In either case, code needs enhancements to handle corner cases (i.e.
output file not provided or is not writeable).
At the moment it doesn't do any of those things:
{{{
