[Octave-bug-tracker] [bug #52303] printing "demo getframe 2" results in emtpy figure

[Dan Sebald]

Follow-up Comment #5, bug #52303 (project octave):

Dmitri, you wrote "The same with png output."  Are you also seeing a blank
output for the PNG files?

I'm getting the following odd behavior:


octave:6> graphics_toolkit qt
octave:7> clf reset;
octave:8> contourf (rand (5));
octave:9> frame = getframe (gcf ());
octave:10> imshow (frame.cdata);
octave:11> set (gca, "position", [0 0 1 1]);
octave:12> print("t1.svg")
GL2PS warning: GL2PS must be compiled with PNG support in order to embed
images in SVG streams
octave:13> print("t1.png")
octave:14> exit


The t1.png file looks fine.  But I don't understand the warning message about
GL2PS needing PNG support, given that I saved the plot in PNG format.  Could
it be a poorly initialized input variable for one of the gl2ps routines?
