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

[Mike Miller]

Update of bug #38323 (project octave):

                Category:                Plotting => Plotting with gnuplot  
                 Summary:  embedded png in svg missing in fltk when printing;
always same png filename with gnuplo => printing image to svg uses same
embedded png filename with gnuplot 4.6

Follow-up Comment #7:

I can reproduce OPs problem with gnuplot 4.6. Works fine with gnuplot 4.4
because there is no png file. Apparently this is a new feature that makes the
svg file smaller by embedding an external png.

A similar problem with this approach is if you print two or more different
images to svg, the embedded png file will always have the same filename,
gp_image_01.png, overwriting any previous plot saves.

This seems to me like unexpected, unscalable, and backwards-incompatible
behavior. I'd be in favor of bypassing this feature of gnuplot if at all
possible.

Regarding fltk, is this not already reported as bug #37753? Let's keep this
one strictly about this gnuplot problem.
