typo3 - PDF thumbnail not appearing -

-

pdf file in text & media element won't show.

i added 2 pdf , 1 image. can see generated markup, pdf come out empty, while image shows:

enter image description here

have tried tests in install tool. every test succeeded except render text truetype font using 'nicetext' option (screenshot)

the cause non-working pdf thumbnails ghostscript not installed. can check in typo3 install tool.

another possibility misconfiguration of imagemagick in typo3, version (im_version_5 setting , friends).

as problem occurs in frontend, should check if path correct and/or if have permission problems writing typo3temp/. if correct, try flushing processed files cache (in install tool) , check if thumbnails in backend appear correctly again.
