ImageMagick/Imagick convert PDF to JPG using native PHP API

问题:

I’m attempting to convert PDF files into PNGs. It works great from the command line (I do have GhostScript 8.64 installed). But from PHP I’m having a problem:

code:

$im = new Imagick($pdf_file); // this is where it throws the exception below 

output:

Fatal error: Uncaught exception ‘ImagickException’ with message ‘Postscript delegate failed `23_1235606503.pdf’: No such file or directory @ pdf.c/ReadPDFImage/612′ in get_thumbnail.php:93 Stack trace: \#0 get_thumbnail.php(93): Imagick->__construct(’…’) 

etc. etc.

I'm not sure what I'm doing wrong here, but I suspect it has something to do with my server configuration somewhere. I'm running: Apache 2.2.11 PHP 5.2.8 ImageMagick 6.4.8-9 GhostScript 8.64

Finally figured this out. The GhostScript executable (gs) wasn't in Apache's environment path. It was in /usr/local/bin. Though I tried several ways to add /usr/local/bin to the path, I did not succeed. I ended up putting a symlink for gs in the /usr/bin directory. Now everything works perfectly.

I don't have the "reputation" on Stackoverflow to add a comment inline above, but there is an extra step I had to perform to get this working on my Mac with the latest Sierra update.

When you enter the command:

sudo ln -s /usr/local/bin/gs /usr/bin/gs 

On the Mac, you may get the error, "Operation not Permitted".

Apparently Apple made a change that the "bin" directory is not editable, unless you disable SIP (System Integrity Protection).

So here are the steps to do that:

  1. Reboot your Mac into Recorvery Mode by restarting your computer and holding down "Command + R" until the Apple logo appears on your screen.
  2. Click Utilities > Terminal
  3. In the Terminal window, type in crutil disable and press "Enter"
  4. Restart your Mac.

I just went through these steps and now my Ghostscript works great and I successfully converted a PDF to JPG.

I am successfully doing this. Here is the code that I am using to do the conversion. We are using this solution commercially. I know this question has been out there for awhile, but it may still help you.

//Convert PDF contract to image using ImageMagik and Ghostscript // NOTE: This will need to be change if running on Linux $source = $appDir."\\".$clientID."\\".$clientID.".pdf"; $dest = $appDir."\\".$clientID."\\".$clientID.".jpg"; //print("c:\\IM\\convert.exe $source $dest "); exec("c:\\IM\\convert.exe $source $dest ");
