[Octave-bug-tracker] [bug #35259] fltk surf plots don't print properly

[Ben Abbott]

Follow-up Comment #14, bug #35259 (project octave):

I have not yet determined why the gl2ps eps-files are violating the operand
stack count. However, I did confirm that adding by saving the initial state
and then restoring it after the eps-file code is run, the problem goes away.

At the top of the eps-file I placed,

/init_state_before_gl2ps save def % save initial state

And at the bottom.

init_state_before_gl2ps def % restore initial state


Then I ran,


epstool --test-eps example.eps


and obtained

File has   %%BoundingBox: 0 0 576 450
Correct is %%BoundingBox: 42 43 510 422
PostScript appears well behaved.
File claims to be EPS.
PASS: File appears to be well behaved EPS.
OK


This isn't a proper fix, but it does give an indication that the gl2ps
eps-file is either leaving an operand on the stack or is eating one.
