manually set delegate path to gs (ghostscript)

Postby imarcw » 2009-07-13T10:29:54-07:00

I'm using IM to convert both PDFs and image files to JPEG. I have IM and ghostscript installed on Mac OS X using MacPorts and everything works fine in Terminal, with PDFs or otherwise.

I tried to call the convert command using AppleScript's "do shell script" command and "convert" wasn't recognized. Thanks to the following Apple developer note, I realized that AppleScript just needed the path to IM to be explicitly set, so instead of convert, I used /opt/local/bin/convert.

http://developer.apple.com/technotes/tn2002/tn2065.html

Problem partially solved. Now I'm finding that when using IM within AppleScript on PDFs, it has the same problem finding the gs command, only I don't know how to specify the path because I'm not calling gs directly.

This is just a shot in the dark, but I'm looking at /opt/local/lib/ImageMagick-6.5.4/config/delegates.xml and wondering if the following line (or another one like it) can be edited somehow to include the full path to gs:

<delegate decode="pdf" encode="eps" mode="bi" command="&quot;gs&quot; -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=0 &quot;-sDEVICE=epswrite&quot; &quot;-sOutputFile=%o&quot; &quot;-f%i&quot;"/>

If so, what is the exact language needed (I already know the path is /opt/local/bin/gs), and if not, what else can I do?

You specify an absolute path. Find out where gs is located and substitute it in the delegates.mgk configuration file (i.e. &quot;/opt/local/bin/gs&quot;);

That worked, just as I speculated it might. Thanks!

I read above three messages about 10 times, my logic device gives up :)
So where can I set path to GS? Having no any delegates.mgk file.

UPD. Oh, I'm blind. Now see the BOLD "&quot;gs&quot;" in first message )

I was having a similar problem (though building ImageMagic from source code) and based on my reading of the configure shell script, this worked for me:

PSDelegate=/usr/local/ghostscript/bin/gs ./configure --prefix=/usr/local/ImageMagick-6.5.4-2 --with-frozenpaths

Hope this helps someone.

This looks like exactly my problem but unfortunately the paths/config files aren't the same.

I am triggering PDF>JPG through Terascript (middleware) calling a shell script. If I construct the command manually and enter it on the command line it works. If I trigger it from the middleware it doesn't.

I assume this solution involves telling ImageMagick where to find Ghostscript.

I have ImageMagic 6.9.3-6 and Ghostscript 9.19 installed but the directories/files are different.

There is no '/opt/local/bin/g's. There is a file '/usr/local/bin/gs'.

I did a 'locate delegates.xml':
/usr/local/Cellar/imagemagick/6.9.3-6/etc/ImageMagick-6/delegates.xml
/usr/local/Cellar/imagemagick/6.9.3-6/share/doc/ImageMagick-6/www/source/delegates.xml
/usr/local/etc/ImageMagick-6/delegates.xml < is an alias or symbolic link to the first occurrence

I have edited all reference to gs to include the path:
&quot;/usr/local/bin/gs&quot;

Still no go.

And the hardest thing is how do I debug this? Is there a console somewhere where I can see the script calling imagemagick and imagemagick calling ghostscript and what the errors are?

Ok, so I do see an error in the Console:

In the IM command, "-verbose" will show you the command IM is using to run Ghostscript. "-debug all" gives information on how it makes that command, by reading delegates.xml.

Thanks for that. I can really see a lot of what is going on. Unfortunately so far I have only been able to see results for the Command Line version, which is successful. I have not been able to view results for the script driven version which is not. I will look into piping the results to a text file if that is possible.

I added ' 2>error.txt' to the command in the script and managed to capture some information. It's fairly longwinded but I located the first mention of gs and copied from there on down:

Re: manually set delegate path to gs (ghostscript)

Postby snibgo » 2016-04-18T20:15:52-07:00

You have:

Code: Select all

convert: FailedToExecuteCommand `"/usr/local/bin/gs"... @ error/delegate.c

This is the path in which you found gs. And the convert command works at the command-line. You could check the gs command at the command line. I suspect that will also work (after you have replaced the temporary filenames).

Perhaps the problem is permissions. Does everyone have permission to run gs?

You might try using proper IM 6 syntax and read the input image before applying processing functions such as -thumbnail and -flatten.

I check permissions this morning and gave everyone permission to run gs.

I'll also try running gs directly.

Has syntax changed? This has always worked previously (and still does on the dev server). Is syntax different for 6.9.3-6?

I'll revisit the command syntax but any pointers you can provide would be appreciated.

Imagemagick does not follow normal unix command syntax. You need to put the image right after convert (unless it is a vector format), then put the settings and then the operators. IM 6 is somewhat forgiving, but may falter if not proper syntax. IM 7 will be much less forgiving. See http://www.imagemagick.org/Usage/basics/#cmdline
