[Octave-bug-tracker] [bug #31161] image() opens gnuplot despite image_viewer("xloadimage %s")

[John W. Eaton]

Follow-up Comment #1, bug #31161 (project octave):

I consider using image viewers other than the Octave graphics renderer
(currently either gnuplot or the new OpenGL+FLTK backend) to be obsolete
because it is highly unlikely that any external image viewer will ever
integrate properly with Octave's other graphics features.  So rather than
fixing the graphics backends to respect the image_viewer selection, I think we
should be removing support for this feature.  But before doing that, I will
discuss it with others on the maintainers mailing list.

If you want to use some external program to view images, it should be
relatively easy to write a function that would save the image using imwrite
and then call system to run the external program to display the image file.
