Imagemagick, Snow Leopard and PDF Conversion

Question

Having difficulties with Imagemagick and Snow Leopard.

Imagemagick was installed using the install script from here here. Everything builds and installs correctly. Imagemagick behave normally for all commands (that I can find) except when trying to convert a PDF. For example,

$ convert my.pdf my.jpg
Segmetation Fault

I thought it may be ghostscript and tried to run the command that Imagegick delegates too (via the -verbose option)

$ convert -verbose spec/fixtures/documents/upload_test_file.pdf test.jpg
"gs" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pnmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72"  "-sOutputFile=/var/folders/Xz/Xz6TDr0DFQaV5J1F7Ndamk+++TM/-Tmp-/magick-4zvJXfSz" "-f/var/folders/Xz/Xz6TDr0DFQaV5J1F7Ndamk+++TM/-Tmp-/magick-O7a9fDyp" "-f/var/folders/Xz/Xz6TDr0DFQaV5J1F7Ndamk+++TM/-Tmp-/magick-rBEzLUsx"

$ "gs" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pnmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72"  "-sOutputFile=my.jpg" "-fmy.pdf"

And it works. It creates the pnmrow file as its supposed to.

I am not sure where to go from here, anyone else seen this or seen it and solved it?

Answer 1

I'm dealing with the same problem here.

Answer 2

me too.

$ identify issue7.pdf 
Segmentation fault

Looks like the imagemagick team is aware of the problem and it should be fixed in version 6.5.5-8.

UPDATE: Actually - The MacPorts package uses the newer version of ImageMagick as of 9/16/09. Try doing a self update and then upgrading php5-imagick.

sudo port selfupdate
sudo port upgrade php5-imagick

This fixed the problem for me.
