[Octave-bug-tracker] [bug #38323] printing image to svg uses same embedded png filename with gnuplot 4.6

[Dan Sebald]

Follow-up Comment #16, bug #38323 (project octave):

I'm attaching my recommended solution to this.  It adds an 'svgstandalone'
option.  Also, if the user decides that the images should be kept separate. 
Put the following code in some .m file and rerun.  Take note of the gnuplot
behavior for creating the auxiliary file.  I'm not quite happy with the way it
does that.  (It creates a new file every time...and then if one relaunches
gnuplot, e.g., exits/restarts Octave the numbering starts from 1 again.) 
However, I don't think there is anything we can do--such as delete existing
files--that would address gnuplot's internal workings.


img = repmat(linspace(0,1,300),300,1);
pts = rand(100,2)*300;
imshow (img);
hold on;
plot(pts(:,1),pts(:,2),'x');
mkdir('mydir');
print('test_aux.svg','-dsvg');
print('mydir/nondir_test_aux.svg','-dsvg');
print('test_emb.svg','-dsvgstandalone');
print('mydir/nondir_test_emb.svg','-dsvgstandalone');
ls -l
ls -l mydir
