convert stops at GS prompt

[twodown]

When I run convert against a pdf it is stopping at a Ghostscript prompt (GS>) When I run i with verbose it seems to be pulling correct delegate entry but not executing in the correct way, stops at a GS prompt. Works correctly on another machine. What does stopping at GS prompt indicate?

convert -verbose /tmp/CCMC.pdf -density 72 -auto-orient -resize "450x450>" /tmp/ImageMagickContentTransformerWorker_target_979552780204846943.png

Your version of GS (8.64) is very old. I suggest you upgrade it.

If that doesn't solve it, what version of IM are you running? If old, upgrade it.

If that doesn't solve it, please post your pdf file somewhere like dropbox.com and paste the URL here.

will upgrade GS, but with same version of ImageMagick and PDF this works fin on another machine/environment:

Do you have the same versions of Ghostscript on both systems?

What do you get from each system when you type

convert -version

[twodown]

Version: ImageMagick 6.9.1-10 Q16 x86_64 2015-08-12 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2015 ImageMagick Studio LLC

I'm not sure why ImageMagick is using different versions of ghostscript in diff environments. How does ImageMagick identify version of gs to use? Is it what resolved from PATH?

[twodown]

obviously gs is not finding something it needs (or is not installed completely) because:

"gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pngalpha" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" "-sOutputFile=/tmp/magick-13028bu5JnBmsJvuj%d" "-f/tmp/magick-13028e9YyY17KSpe8" "-f/tmp/magick-13028weQD1jmtioYW"

works with both 8.64 & 8.7 of gs in working environment. Just not sure how to detect what is missing/corrupt

Did you try upgrading Ghostscript as user snibgo suggested? What is your platform?

Try reinstalling GS (and upgrading) and then install IM again.

[twodown]

Is there a way to see which delegate is actually being used (assuming one is)?

[fmw42]

convert -verbose ...

Will show you which GS version is being used. Or will give an error message regarding GS

How do you know it is stopping at GS? All verbose tells you is that it is using GS unless there is an error message and I do not see one above.

What is your version libpng?

convert -list format

will tell you that and others (but not GS), e.g.


PNG* PNG rw- Portable Network Graphics (libpng 1.6.24)

You can find what version of GS is on your system via

gs --version

at least on unix systems.

I would concur with user snibgo. The best thing would be to upgrade ghostscript and then upgrade IM.
