Hi I use org mode more and more to plot data using python source blocks. If I create pngs, org mode will display these results as an inline image, which is nice. Since I also export my org buffer via latex to pdf, it would be nice to create pdf plots with python, so that I get vector graphics in the pdf. This is easy to do in python's matplotlib, but once I change to pdf output, the images don't get displayed inline in org-mode anymore :( instead, I just get a file:<file> link.
I had a quick look, but can't figure out how to enable this. Should be relatively easy I would think, since emacs already can display pdfs and right-clicking on the file:<file> link will open a new frame with the pdf. Is there any reason not to display them inline? The closest I found is: http://stackoverflow.com/questions/15407485/inline-pdf-images-in-org-mode If it is not that easy, is there a way to run a pre-export and post-export hook that changes my *.png files to *pdf before the export and then changes them back to *.png after the export? Here is a test file ---------------- #+STARTUP: inlineimages * test #+NAME: checkfilename #+HEADER: :var fileout="test--checkfilename.pdf" #+BEGIN_SRC python :session :results file import numpy as np import matplotlib.pyplot as plt fig, ax = plt.subplots(1, 1) X = np.linspace(1, 10) Y = np.sin(X) ax.plot(X, Y) fig.savefig(fileout) plt.close(fig) fileout #+END_SRC --------------------- to create a png, just replace the .pdf in the HEADER with .png this uses ipython and cpaste ------- ; use ipython in org mode (setq org-babel-python-command "ipython3 --no-banner --classic --no-confirm-exit") ; use %cpaste to paste code into ipython in org mode (defadvice org-babel-python-evaluate-session (before org-python-use-cpaste (session body &optional result-type result-params) activate) "Add a %cpaste and '--' to the body, so that ipython does the right thing." (setq body (concat "%cpaste -q\n" body "\n--"))) ------- Arun
