pdf - tty

[jayjay]

If you try to convert certain pdf-files using magick++ without being logged on/using a tty under linux, you get an errormessage:


Magick: Postscript delegate failed `/tmp/magick-12151iAzPpgLwp8cj': No such file or directory @ error/pdf.c/ReadPDFImage/682.

If I redo the same job while being logged on, everything works. It might be related to something within ghostscript.

imagemagick 6.8.6-4
ghostscript 9.07

It seems that ImageMagick cannot find Ghostscript. You will get more info when you use the following statement:

Code: Select all

MagickCore::SetLogEventMask("All");

[jayjay]

strace shows that imagemagick does find ghostscript and also executes it.
However, ghostscript fails with an unrecoverable error. This is probably not related to imagemagick. Ill figure it out on my own. Thanks for your quick response anyway.

Could you post an example program ?

What is your distribution/OS ?
