Imagick/Ghostscript error with PDF input
Question
I have installed ImageMagick on Windows with the DLL for imagick PHP.
I need to convert PDFs into JPEGs. So I also installed Ghostcript.
If I run this command:
convert rose.pdf rose.jpg
it works well. But if I try to reproduce this same functionality in my web environment with PHP:
$im = new imagick('test_pdf.pdf[0]' );
$im->setImageColorspace(255);
$im->setCompression(Imagick::COMPRESSION_JPEG);
$im->setCompressionQuality(100);
$im->setImageFormat('pdf');
$im->writeImage('thumb.jpg');
then my page goes down.
I assume that Imagick PHP fails with PDF to JPEG, because it doesn't know how to use the Ghostscript library gslib .
With this code, however, I can convert PNG to JPEG.
I tried to edit in delegates.xml but I'm not exactly sure how this should be done.
Here are the relevant lines from my delegates.xml :
<delegate decode="pdf" encode="eps" mode="bi" \
command=""@PSDelegate@" \
-q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 \
-dEPSCrop \
-sDEVICE=epswrite "-sOutputFile=%o" -- "%i""/>
<delegate decode="pdf" encode="ps" mode="bi" \
command=""@PSDelegate@" \
-q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 \
-dEPSCrop -dAlignToPixels=0 -dGridFitTT=2 \
-sDEVICE=pswrite "-sOutputFile=%o" -- "%i""/>
Update
I tried to run the ImageMagick with -verbose in order to get additional hints:
convert -verbose 2.pdf 1.jpg
Result:

I made a var_dump when the PDF its loaded
$im = new imagick( __DIR__ . DIRECTORY_SEPARATOR .'test_pdf.pdf' );
var_dump($im);die;
But the page goes down before enter in var_dump.

It works for me :). I had already tried an installation there a few months without success.
I simply followed that topic : Where to find php_imagick.dll for php 5.5.12 for Windows wampserver 2.5?
And after, I've copy/paste the C:/Path/to/ImageMagick/delegates.xml in C:/wamp/bin/php/php.5.5.12/ext/imagick and edit the delegate tag for pdf :
<delegate decode="eps" encode="pdf" mode="bi" command=""C:\Program Files (x86)\gs\gs9.15\bin\gswin32c.exe" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -sDEVICE=pdfwrite "-sOutputFile=%o" -- "%i""/>

Here are the relevant lines from my delegates.xml . I do however not use Imagick nor PHP, so I'm not sure it's the only change you need to make in order to make it work.
First, a form that lets you read it without horizontal scrolling. You have to remove the line breaks as well as the line continuation characters \\ which I inserted:
<delegate decode="pdf" encode="eps" mode="bi" \
command=""/opt/local/bin/gsx" \
-q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 \
-dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=epswrite" \
"-sOutputFile=%o" "-f%i""/>
<delegate decode="pdf" encode="ps" mode="bi" \
command=""/opt/local/bin/gsx" \
-q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 \
-dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=ps2write" \
"-sOutputFile=%o" "-f%i""/>
Now the original lines. You need to scroll horizontally to see it fully and in its original shape:
<delegate decode="pdf" encode="eps" mode="bi" command=""/opt/local/bin/gsx" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=epswrite" "-sOutputFile=%o" "-f%i""/>
<delegate decode="pdf" encode="ps" mode="bi" command=""/opt/local/bin/gsx" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=ps2write" "-sOutputFile=%o" "-f%i""/>
These lines are from my Mac OS X version of ImageMagick, 6.9.0-0 Q16 x86_64 2014-12-06 .
As you can see, it doesn't use a @PSDelegate -syntax. Instead it contains the full path to the Ghostscript executable, in my case /opt/local/bin/gsx .
For your case, it should possibly be the full Windows path to your Ghostscript executable, which usually is named gswin32c.exe or gswin64c.exe .
Your problem with the strange @PSDelegate possibly comes from the fact that you installed ImageMagick/Imagick before you installed Ghostscript, and installed Ghostscript only afterwards....
Update
Maybe you should try for your Windows/Ghostscript installation the following lines in your delegates.xml file:
<delegate decode="pdf" encode="eps" mode="bi" command=""C:/Program Files/gs/gs9.15/bin/gswin64c.exe" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=epswrite" "-sOutputFile=%o" "-f%i""/>
<delegate decode="pdf" encode="ps" mode="bi" command=""C:/Program Files/gs/gs9.15/bin/gswin64c.exe" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=ps2write" "-sOutputFile=%o" "-f%i""/>
Note , you do not need to use backslashes (' \\ ') -- Ghostscript and ImageMagick are just fine with forward slashes (' / ') on Windows.
