In some cases latex genarage empty png.
I found that dvips generate wrong ps file in some cases (tested on PSTricks package).
Convert can't read that file

convert-im6.q16: geometry does not contain image `test.ps' @ warning/attribute.c/GetImageBoundingBox/247.
# identify test.png
test.png PNG 1x1 1x1-1-1 8-bit sRGB 123B 0.000u 0:00.000

It seems dvips bug https://groups.google.com/forum/#!msg/comp.text.tex/VvDvcQlCaag/X4pyuX999nIJ

I needed to remove -E (Try to create EPSF) option hard coded in class.latexrender.php and all works ok.

Hey!
I'm running on nginx and debian 8.
I tried the quick and dirty fix on
https://www.dokuwiki.org/plugin:latex#local_with_mactexlatex_compilation_failed

Still not working.
Thanks for your help!

I can't use
\begin{align_}
x^2 + y^2 &= 1
\ y &= \sqrt{1 - x^2}.
\end{align_}
it should be part of amsmath- package and is a replacement of eqnarray

Dokuwiki version 2023-04-04a "Jack Jackrum" and Debian 11 "bullseye" with php 7.4 work perfectly.

After update Debian to 12 with php 8.2 I get error when open pages with LaTex formula '$2+2 = 4$' or $$ 2+2=4$$
Error: Call to a member function getFormulaURL() on null
When open admin page 'https://my-doku.site/?do=admin&page=latex' and run test I get
Error: Call to a member function getPicturePath() on null

Doku wiki ver: Rincewind

Once I click "Delete!" button in the admin page, I moves to "doku_do_admin" page which says "This topic does not exist yet".

It seems that there is a bug in "admin.php" at the line number 154:

... form action="'.wl($INFO['id']).'?do=admin&page='.$this->getPluginName().'" ...

I think that the question mark(?) should be "&" mark.

... form action="'.wl($INFO['id']).'&do=admin&page='.$this->getPluginName().'" ...

I've just converted a bunch of pages over from mediawiki, where the tags are used rather than or the other tags in your plugin. Would it be too much of a hassle to support math tags as well?

From: https://www.dokuwiki.org/plugin:latex#dollar_signs

Instead of a space add an "*" to the ''EntryPattern'' and the "ExitPattern" in "dollar.php".

1. This is a very rare combination and
2. it will work for all those languages which have a currency symbol after the ammount. E.g. in many european countries we are used to write 2.000,00$
3. It will not break all existing pages.
   So change "dollar.php" to:

<code>$this->Lexer->addEntryPattern('\$\*(?=.*\$)',$mode,'plugin_latex_dollar');  </code> 

and also add an ''*'' to the ExitPattern:

<code>function postConnect() { $this->Lexer->addExitPattern('\*\$','plugin_latex_dollar'); }</code> 

The syntax will change to

 $* a + b = c *$ 

which is close to the comment-plugin Syntax (/* a comment */). And $2000, 2.000,00$ and a $ alone will work as before.

Hey! That's a great plugin I must say!
I have a question, is this plugin compatible with the new version of DokuWiki, 2014-09-29a "Hrun"?

There seems to be a data format compatibility breaking issue in the plugin introduced by the latest development upgrades on the wiki. I tried to figure out the details but cannot get beyond this point figuring out where in breaks in the plugin code.

Any plans to update this or will this plugin become redundant now?

Thanks

In my installation LaTeX is only rendered between the .. tags.

Outside the tags no images of equations appear, all commands ($...$/$$...$$/\begin{xxx}...\end{xxx}) are ignored and there are no PNG files generated in dokuwiki/data/media/wiki/latex.

The example of the admin page works, there are no errors and all files are generated in dokuwiki/data/media/wiki/latex.

My system: Debian 10 (buster) with DokuWiki release 2016-06-26a "Elenor of Tsort"

Thanks for your help!

I've installed the dokuwiki and this plugin on Windows Server 2019. Everything seems to be working except the final PNG conversion. I've attached screenshots to go along with this. The test render fails saying it can't find the PNG file. If I save the test files and then manually run the same command ("C:/Program Files/ImageMagick-7-portable/convert" -density 120 -trim -transparent "#FFFFFF" 48743788316f095c1e12022620e8d979.ps 48743788316f095c1e12022620e8d979.png 2>&1) in the command prompt, it completes and generates a PNG file just fine.

Any idea why it's acting this way? It gives the same file not found error if I try to run the command from outside of the latex tmp folder...
