Extension:PdfHandler

This is the README file for the PdfHandler extension for MediaWiki software. The extension is only useful if you've got a MediaWiki installation; it can only be installed by the administrator of the site.

The extension shows uploaded pdf files in a multipage preview layout. With enabled WebStore the extension generates automatically Images from the specified page.

This is the first version of the extension and it's almost sure to have bugs. See the BUGS section below for info on how to report problems.
