I have re-tested the code from comment #2 with the new Octave 5.1.0 release (official w64 installer) on Windows 7. I see:

  • The "holes" in the plot, as originally reported, are still gone (as already observed in my comment #5).
  • The pdf output is not cropped in any wrong way. (This is better as observed in my commment #5).

The output is still not perfect (look at the z-axis thickness between 4 and 5). But I would summarize that it looks equally good as the rendered screen output (which has the same z-axis look in this case). So my suggestion would be to CLOSE this bug report as "fixed".

I will attach my two pdf output files, so anyone can judge himself.

Version 4.2.0 is deprecated and no longer supported.  Please try with the latest stable release which is 5.1.0.  The problem is likely to have been fixed.

I have tested this with Octave 4.2.0 under Windows XP.

Using the test code from comment #2 I see:

  • The resulting pdf files do not have "holes" any more.
  • But the figures in the pdf files are now both cropped at the top.

I have run this script on Linux machine (ubuntu) with gl2ps-1.3.8 and there is no problem. May it's a ghostscript problem,
Octave 4.0.0 os bundlesd with 1.3.8.

(BTW: using
print test.ps
with MXE-Octave on windows creates a monochrome postscript, and not

I can confirm this on a Windows XP virtual machine.  The problem is only with OpenGL, gnuplot printing works fine and can be a workaround for the original bug reporter.

The plot is also fine on a Linux machine that uses gl2ps-1.3.6.  MXE Octave is using gl2ps-1.3.8 now which could be the issue.  I don't know what version of gl2ps was bundled with 4.0.0.

The script is probably:

 set (gcf, "papersize", [6.4, 4.8])
set (gcf, "paperposition", [0, 0, 6.4, 4.8])
[x,y] = meshgrid(0:.1:5);
z=2.5 + 2.5*tanh( (1-(x-3).*(x-3)-5*(y-4).*(y-4))*5 );
print -mono test1.pdf
print test2.pdf

I presume that the bug is related to gl2ps, because plotting with
gnuplot does not produce this "holes" in the image.
The catogory should be changed to "Plotting with OpenGL".

Could you upload the sample script, or re-post on the bug tracker but use the verbatim tags?

The script

set (gcf, "papersize", [6.4, 4.8])
set (gcf, "paperposition", [0, 0, 6.4, 4.8])
[x,y] = meshgrid(0:.1:5);
z=2.5 + 2.5*tanh( (1-(x-3).*(x-3)-5.*(y-4).*(y-4))*5 );
print -mono test1.pdf
print test2.pdf

leads to pdf's with "holes" as attached.
See e.g. the corner near (5,5)
