PDF's not displaying after import

Please see bug report 322981 on my site.
If a PDF is included in a page, then it displays as an empty block.
Another issues is that clicking it doesn't open the file. it sends the user to a very confusing page that states that the user is looking at the contents of the file. Which is not true.
If the user clicks the file then they want to view the file contents. Not go somewhere else. I understand that this is how VW4 now works, but from an end user point of view it doesnt work. Its a large step back from VW3.

Your environment does not have support for treating PDFs as images.

PHP was not compiled with the Imagick extension. While your server may have the ImageMagick binaries installed, along with the appropriate GhostScript extension, which was needed in vBulletin, vBulletin had provided command-line access to the binaries, while XenForo requires the presence of the Imagick PHP extension.

In your environment, it would be necessary to download the PDF in order to view it. The link in the wiki page sends the user to the correct download page for the PDF.

The only issue I notice here is that the generic file icon is not showing when FILE has been used in 'thumbnail' mode and the file cannot have thumbnails. I have fixed this in the next release. Everything else you describe is working as designed, and by the way, it's exactly how the FILE BB-Code (then IMAGE) worked in VW3, so it is in no way a step back or a regression. Your gripe is with the conversion of ATTACH to FILE in VW4, which gives all wiki attachments a separate description and download page, has been litigated ad nauseum elsewhere.

Marking this as Working as Designed.

Thats not correct. XenForo doesn't require ImageMagick. It requires GD.
XenForo System Requirements: https://xenforo.com/purchase/
We actually switched from ImageTragick to GD due to this requirement.
IMHO Imagemagick should not be used at all due to vulnerabilities.

GD has no support for PDFs.

XenForo requires AT LEAST GD, but will use ImageMagick if the Imagick extension is installed. XenForo requires Imagick in order to use ImageMagick. But yes, there are vulnerabilities in ImageMagick.

How about displaying a PDF icon or just the link when there is no ImageMagick?
I would like to avoid ImageMagick. My host objects to installing it.
