Bug: latex blocks preview inline [9.2.1 (release_9.2.1-217-g232160 )]

Bug: latex blocks preview inline [9.2.1 (release_9.2.1-217-g232160 )]

[Joao Cortes]

Consider this latex source block, 

      #+HEADER: :file latex.svg
      #+HEADER: :results drawer
      #+BEGIN_SRC latex 
	\begin{tikzpicture}
	  \draw[red] (0,0) circle (1cm);
	\end{tikzpicture}
      #+END_SRC

I would like to preview the result inline using
org-toggle-inline-images.

When using the latest release from https://code.orgmode.org/bzg/org-mode
(9.2.1-217-g232160), the result is

      #+RESULTS:
      :results:
      :end:


When using the org-plus-contrib package from the org archive
(9.2.1-8-g1b1797-elpaplus),

      #+RESULTS:
      :results:
      [[file:latex.svg]]
      :end:
      
I was expecting to get the second result with both installations as it
seems to be the intended behaviour.

Is there any way to tweak the latest release (from
https://code.orgmode.org/bzg/org-mode) to get the second output?

Thanks
Joao

Hi,

>       #+HEADER: :file latex.svg
>       #+HEADER: :results drawer
>       #+BEGIN_SRC latex

I think you're missing some headers to get it working. For example, I
use the following defaults to preview/export images generated with
tikz to html/markdown documents:

      org-babel-default-header-args:latex '((:results . "file raw")
                                            (:exports . "results")
                                            (:cache . "yes")
                                            (:headers . ("\\usepackage{tikz}"))
                                            (:imagemagick . "yes")
                                            (:fit . "yes")))

Try adding them to you src block or to you config. :cache and :fit
aren't necessary for your goal but desirable anyway. The others I
think you will need them.

Of course, if you're embedding your tikz environment in a document
exported to latex, simply embed the fragment (that is, without the src
block) and preview it with C-c C-x C-l.

I don't know what is this, but could it be shipped with different
babel defaults?

Best regards

Also, make sure imagemagick is installed.

Btw, you might find this useful for previewing babel-generated images:

(defun my-org-babel-redisplay-images ()
  (when org-inline-image-overlays
    (org-redisplay-inline-images)))
(add-hook 'org-babel-after-execute-hook
          #'my-org-babel-redisplay-images)

This reloads the previewed images each time they potentially change.
