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="&quot;@PSDelegate@&quot; \
   -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 \
   -dEPSCrop \
   -sDEVICE=epswrite &quot;-sOutputFile=%o&quot; -- &quot;%i&quot;"/>

<delegate decode="pdf" encode="ps" mode="bi" \
    command="&quot;@PSDelegate@&quot; \
   -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 \
   -dEPSCrop -dAlignToPixels=0 -dGridFitTT=2 \
   -sDEVICE=pswrite &quot;-sOutputFile=%o&quot; -- &quot;%i&quot;"/>

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.

Can you add -verbose to your successful PDF conversion command? Run convert -verbose rose.pdf rose.jpg. You'll see the Ghostscript command which is called by ImageMagick. Maybe this gives you a hint about what you need to change in your Imagick setup... — Kurt Pfeifle
Strange... I find the [ghostscript library] Files/gs/gs9.15/bin/gswin64c.exe" part a bit strange. Are you sure you copy'n'pasted it correctly?!? -- I'm guessing this should be "C:/Program Files/gs/gs9.15/bin/gswin64c.exe" — Kurt Pfeifle
yes , its copy'n'pasted including [ghostscript library] I had the same doubt , i tried with Files/gs/gs9.15/bin/gswin64c.ex but i had no success , i will try now with C:/Program files — Guillermo Nahuel Varelli
"I assume that..." don't assume. What is the actual error in your log file? — Danack
I dont have errors when i run convert -verbose 2.pdf 1.jpg , but when i use the php code to convert the PDF the page goes down. — Guillermo Nahuel Varelli

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="&quot;C:\Program Files (x86)\gs\gs9.15\bin\gswin32c.exe&quot; -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -sDEVICE=pdfwrite &quot;-sOutputFile=%o&quot; -- &quot;%i&quot;"/>
