You first export your org-file to latex. the function I sent assumes the tex file has the same basename as the org-file, and ends in .tex. Then, with your org-file as the current buffer, call that function. It will modify the latex file by replacing your \includegraphics lines with the equivalent line minus the .png. then you need to manually build the latex file if you want the pdf. I am not sure what an ebb file is, or what the difference in latex vs xelatex is. https://github.com/jkitchin/jmax/blob/master/ox-manuscript.el John ----------------------------------- John Kitchin Associate Professor Doherty Hall A207F Department of Chemical Engineering Carnegie Mellon University Pittsburgh, PA 15213 412-268-7803 http://kitchingroup.cheme.cmu.edu On Fri, Apr 25, 2014 at 11:23 AM, Leu Zhe wrote: > Dear John， > > Thanks very much for your help. > > I have tried your code but nothing happened.
