octave-ipython.ipynb example rendering problems

[henczati]

After adding the https://github.com/sagemath/cloud-examples.git repo to a project (New.. -> Add from web) and then opening cloud-templates/octave/octave-ipython.ipynb, in In [6]: after the plot command I get the following warnings:

warning: print.m: epstool binary is not available.
Some output formats are not available.
warning: print.m: fig2dev binary is not available.
Some output formats are not available.

By the way, I got the same thing when on my local linux box I installed octave from the repos (together with the octave-miscellaneous package that has the publish command) and then ran publish on a script file containing a plot. Installing the epstool and transfig (containing fig2dev) packages solved it for me.

Hmm. Unfortunately, both the epstool and transfig Ubuntu packages are installed already. Hmmm....?

Hmm. Ok. Could you check if you have the same warnings in that file then?

I Also have a load of ghostscript errors in In [7]: and In [8]: btw..

GPL Ghostscript 9.05: Error: Font Renderer Plugin ( FreeType ) return code = -1

x16 in In [7]: x24 in In [8]: Interestingly there are also graphics displayed under the error and warning messages...

Edit: ...with awful-looking text and numbers. :)

[henczati]

The text and numbers look weird in http://nbviewer.ipython.org/github/blink1073/oct2py/blob/master/example/octavemagic_extension.ipynb, too, so that's probably their doing. :) But at least they seem not to have the font problem.
