6.8.9-7: Postscript/PDF failure with ghostscript 8.70

[remi]

Ghostscript 8.70 is the standard version on RHEL / CentOS 5 and 6

With this version and ImageMagick 6.8.9-7 reading .ps or .pdf fails
Reverting coders/ps.c and coders/pdf.c to version 6.8.9-0 solves this issue.

From a quick analysys of the changes in these coders

- previous : rely on command exit code, and retrieve message if needed
- current : rely on output and catch message with PostscriptDelegateMessage

Problem: ghostscript succeeds but display a warning, which raise an exception in ImageMagick.

Code: Select all

Exception: PDFDelegateFailed `[ghostscript library] -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pam" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" -dUseCIEColor "-sOutputFile=/tmp/magick-320807xqpPIxdkvMk%d" "-f/tmp/magick-32080x_2jLbAXRyaJ" "-f/tmp/magick-32080lL2VmTkUoDy7"': -dname= must be followed by a valid token @ error/pdf.c/InvokePDFDelegate/256

Issue reported by users of my repository where "recent" versions of ImageMagick are available for Fedora / RHEL / CentOS...

We need to reproduce the problem before we can offer a solution. Under CentOS 5.10 and ImageMagick 6.8.9-7, we tried:

Can you try these commands? Do they work for you?

You can also add --with-gslib=no to your configure commandline. ImageMagick will then use the 'gs' program rather than the gs library.

Yes, convert works... so I need to find why it doesn't work from php/imagick...

[remi]

We can close this one.... very strange conflict in PHP land between gd and imagick extension...

Code: Select all

$ php56 -n  -d extension=imagick.so -r 'var_dump($im = new Imagick("../foo.pdf"));'
object(Imagick)#1 (0) {
}

$ php56 -n  -d extension=gd.so -d extension=imagick.so -r 'var_dump($im = new Imagick("../foo.pdf"));'
