Re: A tip for converting the result directories xmgrace files to eps and png -- June 13, 2013 - 16:36

I am happy that you think it is great. :-)

As soon there is a file type, which can fast be opened by a image viewer, I am happy.

It works for PNG here, and it is very probably a compilation issue.

I have PNG as a possibility to print in my xmgrace menu.

I found the commands here:

http://ringo.ams.sunysb.edu/index.php/Xmgrace

This is for EPS and PNG, but I havent found options for JPEG yet.

I would say the "more the merrier". 

It take's time to create scripts, but no time to delete.

That's a great trick!  My knowledge of Grace is not that extensive.
You know what would be even better - if the
relax_disp.plot_disp_curves user function created this script and
dropped it into the directory with the Grace files!  I've now shifted
the code into the
specific_analyses.relax_disp.disp_data.plot_disp_curves() function.
Such a script could easily be created at the end of this function -
best by calling a special function in lib.software.grace.

What would be good would be to generate one script for the PNG files,
maybe called 'grace_to_png.sh' just to be more informative to the user
that this is for conversion and that it is a shell script, one for EPS
files called possibly 'grace_to_eps.sh', and a third called
'eps_to_pdf.sh'.  The plot_disp_curves() function can even make them
executable for the user.  I suggest that the *.tmp files be removed by
the script at the end.

The only problem is that I tried this and received error messages and
broken files:

Unknown device: DEVICE "PNG" FONT ANTIALIASING ON
Unknown device: DEVICE "PNG" OP "compression:9"
File modifications are disabled in safe mode: PRINT
File modifications are disabled in safe mode: PRINT
disp_:70@N agr

The EPS files are created successfully.  I'm not sure why the PNGs
failed, maybe it's not compiled in.  JPEG and SVG are present in the
print options through the GUI though, so maybe scripts for these
formats can be very easily created as well.  A simple loop over 'PNG',
'EPS', 'SVG', and 'JPEG' could create separate scripts for each format
and make them executable, and then at the end the 'eps_to_pdf.sh' can
be created.  The script generation could be documented in the user
function docstring.  What do you think?

Cheers,

Edward
