[Octave-bug-tracker] [bug #54693] Qt/FLTK - export as PNG - wrong image size and aspect ratio

[Pantxo Diribarne]

Update of bug #54693 (project octave):

                  Status:                    None => Invalid

Follow-up Comment #1:

With OpenGL toolkits (qt and fltk) you need to use the figure "paper*"
properties to control the aspect ratio of printed output. In particular,
unless the "paperpositionmode" is "auto"  (which is not the default), the
aspect ratio will be given by "paperposition". 

What you want is something like this


figure ("position", [100 100 600 300], ...
        "paperpositionmode", "auto");
plot (1:10)
print /tmp/toto.png


Those properties are documented here:

https://octave.org/doc/interpreter/Figure-Properties.html#XREFfigurepaperposition

I'll close this report as invalid since what you describe is intended for
Matlab compatibility. Or, do you want to make it a gnuplot toolkit bug :-) ?
