Imagick opening PDF 1.8 - why can not open?

[lubosdz]

Does anybody know, why is imagick not capable to open PDF files higher than version 1.5 ?

currently, there is official 1.8 PDF version.
is this caused by ghostScript or Imagick is not supporting this at all?

My question is simply: How can I use Imagick to convert PDF 1.8 document into image?

Thank you.

I think Imagick support stopped a couple of years ago and may not be able to work with anything newer than 1.5 or it could depend on the version of Imagick you are using.

ImageMagick relies on the Ghostscript delegate library or program to render PDF. Try your PDF with Ghostscript, if it fails to render, the limitation is in Ghostscript. Try it with mudraw. Does that work?
