[Mediawiki-l] texvc md5 question

[Andrea Ganduglia]

Hi. I'm working around MediaWiki code and I have question about textvc.

If I calculate md5 hash directy from tex_string I obtain a different
md5 hash that texvc, example:

$texstring= '\sum_{3}=x';
$md5_texstring = md5($texstring);
$TEXVC_OUTPUT  = `./texcv TMPDIR IMGDIR "$texstring" 'iso-8859-1'`;
...
print $md5_texstring."\n";
print $texvc_image_name."\n";

How can I obtain texvc md5 hash **before** run it?
