The PDF Pro Viewer Macro allows users to load and view PDF files inside a wiki page. The Viewer supports a double full screen mode:

  • first going full screen in your browser
  • then going full screen on your computer if your browser supports that mode.

The PDF location could be the current wiki page, another wiki page or an external URL.


External Resources




Below are described the parameters of the PDF Viewer Macro that need be used in order to define the way a PDF file is displayed in a wiki page.

NamePretty nameMandatory?DefaultDescription
asauthorDelegate my view rightcancel0

If this value is true (or 1 or yes) and the viewing user has no access to the document containing the PDF file, the PDF file could still be viewed on behalf of your view right (as long as you have view right on the containing document).

This parameter is helpful when you want to add to a page B a macro pointing to the PDF from another page A, that is protected for some users. Note that the view right is delegated only if the last person that saved page B had indeed view rights on page A. Also, this will not alter the view right on page A.

documentDocumentcancelcurrent documentReference to the XWiki document to which the file is attached (e.g. xwiki:Path.To.Document). The xwiki: part can be ignored if the file is located in the current wiki). If file argument is an absolute URL, this argument is ignored.
fileFileacceptN/AName or the absolute URL of the PDF file.
heightHeightcancel1000The viewer height, accepts values in pixels or in percentage.
widthWidthcancel100%The viewer width, accepts values in pixels or in percentage.

Using the macro from WYSIWYG editor

Edit a wiki page in WYSIWYG mode and look in the tool bar for the icon (XWiki Macro), search for PDF Viewer Macro and fill in the parameters values. 

Using the macro from wiki editor (code)

PDF file attached to a wiki page

To note that when using this option to display a PDF on a wiki page, the URL for the PDF will be generated using the XWiki API which can handle different setups for the wiki (path based, domain based, alias updates, etc).

{{pdfviewer file="gsoc.pdf" document="dev:GoogleSummerOfCode.WebHome" asauthor="1" height="900" width="80%"/}}

PDF file attached to a terminal wiki page

When having a PDF file attached to a terminal page, the syntax is slightly different, leaving out the "WebHome" mention.

{{pdfviewer file="gsoc.pdf" document="dev:GoogleSummerOfCode" asauthor="1" height="900" width="80%"/}}

PDF accessed from an external resource via URL

When using an absolute/explicit URL to display the PDF on a wiki page, keep in mind that you might need to update the URL if the alias of the source where the PDF is located will be changed.

If the absolute URL is from an external domain, you might encounter an error which is addressed in the Trusted Origins subtitle.

{{pdfviewer file="http://dev.xwiki.org/xwiki/bin/download/GoogleSummerOfCode/WebHome/gsoc.pdf" /}}


Display multiple PDF files in the same page using a tab system layout

Add more PDF files, separated by comma.

{{pdfviewer file="TLSanalysis.pdf,H-MSD2018.pdf"/}}



Administration Page

Trusted Origins

If you use URLs of PDFs from external domains, you might encounter an error with the following message `Message: file origin does not match viewer's`. 1712216925490-172.png

This error appears, as the message suggests, because domain of the viewer is different from the domain where the pdf is located.

To avoid this problem, you should append the domain of you wiki and/or subwiki to the `Trusted Origins` field of the Administration Section.


With Credentials

If you are trying to access pdf files located on servers that need authentication and your cookies contain the validation data, you will need to set the `With Credentials` field to yes. This way, the cookies will be forwarded when making a request to the said pdf file.
