[Mediawiki-l] Funtion wfImageDir missing

[Günter Gratzer]

hello,
I upgraded MediaWiki from 1.9 to 1.11.0 on Windows. We use the wikipdf extension. After the upgrade the pdf conversion does not work any more because the function wfImageDir which was located in includes\ImageFunctions.php is missing.
 
Anyone knows which function I can use instead? I didn't find anything about this function on the web.
 
Thanks
 
Günter
