All the math images have a white background. So I changed wgTexvcBackgroundColor to be transparent. So all the new math renderings are transparent, but the existing ones are still white. Is there a way to force them to re render, under maintenance or something?
I don't know this part of MediaWiki, so I've been poking around in the docs and the source. Grepping through the maintenance directory, it doesn't seem like there is a script for this.
However, if $wgMathCheckFiles is set to true (which it is by default), then MediaWiki should ensure that the files generated by texvc exist. If I'm reading the manual page (http://www.mediawiki.org/wiki/Manual:$wgMathCheckFiles) right, then you should just be able to move the existing images to another directory and new images should be generated on demand.
I've dropped a few more notes into http://www.mediawiki.org/wiki/Manual:Math. The changes are currently awaiting review, so you'll need to log in or visit http://www.mediawiki.org/w/index.php?title=Manual:Math&stable=0&redi... to see them.
