ditta image size

ditta image size

[SabreWolfy]

The following Org file:

--8<---------------cut here---------------start------------->8---
* Picture
#+BEGIN_SRC ditaa :file hello-world.png :cmdline -r -s 1.0
+----+
| Hi |
+----+
#+END_SRC
--8<---------------cut here---------------end--------------->8---

rendered to LaTeX and then PDF (C-c C-e l o) with ditaa version 0.9 and
org-version 8.2.4 in Emacs 24.3.1 produces output with the ditaa image very
much enlarged and pixelated. How can I avoid this?

I prepared another, more complex diagram, which is now rendered smaller than
before, but is still of poor, pixelated quality. This is a PNG scaling
problem? GraphhViz will give better quality?

Hi,

You have a couple of options I believe. Firstly, take a look at 14.8.2.25
`:post` from the org manual, which provides an example of automatically
wrapping a generated image with the necessary LaTeX attributes to correct
the sizing. Secondly, there is a ditaa addons pack which enables you to
generate eps. I've not tried this, but it might be worth a try.

Cheers,

Will
