[Phpwiki-talk] Latex and png images.

[Chris O'H. <cm...@gm...>]

Hello,

I am running phpwiki 1.3.11p1  on my Kubuntu Dapper machine.

I am trying to get the Tex2png plugin working.

The first error I got related to the /images/tex directory not being writeable.

I created the directory in /usr/share/phpwiki/ so that I now have

/usr/share/phpwiki/images/tex

I can now see the png files being created in this directory and the
error about not being writeable has gone away.

However, whenever I use the wiki, the latex code is still displayed.
ie the alt description in the <img> tag.  I can see the correct
reference for src="images/tex/12345abcde.png" but the images isn't
displayed.

I've set the read write permissions to everyone

And I've checked in the config.ini file and made sure png is included
in the inline images configuration.

Is there something else I need to do to make it go?

Thanks for your time and attention.

Chris

"/usr/share/phpwiki/images/tex" is the file location
but the webserver must find it under "images/tex"
so must set an alias for images.
or better symlink from images to /usr/share/phpwiki/images/tex

[Chris O'H. <cm...@gm...>]

Thanks for the reply.

I might need a more explicit instruction here.

In the apache.conf file in /etc/phpwiki there are the alias definitions.

Alias /phpwikidata   /usr/share/phpwiki/
Alias /phpwiki         /usr/share/phpwiki/index.php/

As per your suggestion, I have tried adding the following lines.

Alias /phpwiki/images/tex    /usr/share/phpwiki/images/tex/
or
Alias /images/tex                       /usr/share/phpwiki/images/tex/
or
Alias /phpwiki/images/         /usr/share/phpwiki/images/tex
or
Alias /phpwiki/images/         /usr/share/phpwiki/

The remainder of the apache.conf file is

<Directory /usr/share/phpwiki/>
       DirectoryIndex  index.php
       Options +FollowSymLinks
       AllowOverride None

etc

The images are still not displaying.
Any thoughts of comments appreciated.

Chris

Re: [Phpwiki-talk] Latex and png images.

[Chris O'H. <cm...@gm...>]

Replying again

I can see in the webserver access logs

... "GET /phpwiki/images/tex/c0e78585c2add482621c0a58207171029.png
HTTP/1.1" 304 1593 "http://ohalloran.homeip.net/phpwiki/" "Mozilla/5.0
(Windows; etc etc

I was wondering if the 304 response was indicating somethings about the setup?


Thanks again.

304 is just 304, not modified since.

images/tex/c0e78585c2add482621c0a58207171029.png is treated as empty 
wikipage text/html, and not as image/png

in your accesslog there must be
"GET /phpwikidata/images/tex/c0e78585c2add482621c0a58207171029.png ..."
otherwise you'll see no image

Have you already tried the real and working latex plugin? TexToPng
This requires PLUGIN_CACHED_CACHE_DIR to be configured, but this plugin 
should work with your non-simple setup.

your setup is clear.
/phpwiki/images resolves in your setup to /usr/share/phpwiki/index.php/images.
this will not work.
you have to change the source of the problem: the plugin, which wants
/phpwiki/images and not /phpwikidata/images.

Thanks for your help.
I am not entirely sure what you mean but I will have a think about
what you've said.
Are you suggesting that I need to change some code in the Tex2png plugin?
