[Octave-bug-tracker] [bug #34142] printing to gif does not output text elements.

[anonymous]

Follow-up Comment #1, bug #34142 (project octave):

while png does output correctly I also find similar issues if I try to create
debug output for png (as a aid to finding the gif bug.).


 print ('plot.png','-dpng');
 drawnow ('png','plot.png', false,  "debug.gp")
gdImageStringFT: Could not find/open font while printing string -0.8 with font
{}
gdImageStringFT: Could not find/open font while printing string -0.6 with font
{}
gdImageStringFT: Could not find/open font while printing string -0.4 with font
{}
gdImageStringFT: Could not find/open font while printing string -0.2 with font
{}

this is the debug output for either gif or png, it fails as soon as it tries
to add the title:

set title " non-rad : rad = 0.3:0.7" font "{},10" enhanced;
set xlabel "dSST / K" textcolor rgb "#000000" font "{},10" enhanced rotate by
0.000000;


A fairly simple and obvious bug: if no font is explicitly set it is outputting
octave's indication of an empty cell array instead of skipping the unnecessary
font specifier and comma.


Please fix gif output.
