Re: Error when a figure is saved in DXF format

[Emil M. Oanta]

Dear All,

The same script run in Ubuntu under Octave version 4.2.2 has the warning:

Stage: save the diagram(s) in the following png file:/home/emil/octave-workspace/Interpolari/00099_Speed-Torque_Mech_Charact_01/00099_Speed-Torque_Mech_Charact_01_laws_2019_05_09_17_06_15.png
warning: print.m: fig2dev binary is not available.
Some output formats are not available.
warning: called from
    __print_parse_opts__ at line 388 column 9
    print at line 316 column 8
    saveas at line 105 column 3
    SplInt at line 1176 column 4

in the following sequence of my script

1174   %
1175   disp(strcat("Stage: save the diagram(s) in the following png file: ",png_filename));
1176   saveas(fig, [png_filename], "png");
1177   pause(2);
1178   %

In   /usr/share/octave/4.2.2/m/plot/util/private/__print_parse_opts__.m   the according sequence is

379
380  if (warn_on_missing_binary)
381    if (isempty (arg_st.ghostscript.binary))
382      warning ("print:missing_gs", "print.m: Ghostscript binary is not available.\nOnly eps output is available.");
383    else
384      if (isempty (arg_st.epstool_binary))
385        warning ("print:missing_epstool", "print.m: epstool binary is not available.\nSome output formats are not available.");
386      endif
387      if (isempty (arg_st.fig2dev_binary))
388        warning ("print:missing_fig2dev", "print.m: fig2dev binary is not available.\nSome output formats are not available.");
389      endif
390      if (isempty (arg_st.pstoedit_binary))
391        warning ("print:missing_pstoedit", "print.m: pstoedit binary is not available.\nSome output formats are not available.");
392      endif
393    endif
394    warn_on_missing_binary = false;
395  endif
396

The automatically generated PNG file is OK while the automatically generated DXF file cannot be used (it has only 43 lines).

There were no warnings or errors regarding the DXF format.

Thank you for the answers,

Emil

If I try the following with Octave-5.1.1 (next version to become stable
5.2.0):

plot (0:10)
print ('tst.dxf', '-ddxf')

I get:
warning: print: "dxf" format is no more officially supported

TBH, I didn't even know that DXF format was once supported.
