Features

PdfHandler shows uploaded pdf files in a multipage preview layout. 

Together with the Proofread Page extension enabled, PDF files can be displayed side-by-side with text for transcribing books and other documents, as is commonly done with DjVu files (particularly in Wikisource).

Usage:

• The main usage of the PdfHandler extension is without user interaction. If you upload a new pdf file, the metadata will be stored in the database, and then this file can be shown in a multipage preview layout like the djvu handler does. Without this extension, pdfs will not display properly when uploaded.
• Additionally, this extension allows Extension:ProofreadPage to handle pdfs in side-by-side view for transcribing/proofreading, as is done on Wikisource
• Another option, introduced quite long ago (r25575), is to use it to display PDF files as an image, showing a single page at a time.
• Because PdfHandler extends ImageHandler, you can use all the arguments that you would for an Image -- for example: thumb, right/left, caption, border, link, etc.
