PDF to JPG not working from php front end
It works fine on command line using
convert test.pdf test123.jpg

the path for both are /usr/bin/convert and /usr/bin/gs
versions are
imagemagick 6.5.4-7
ghostscript 8.70

I have tried this code and a couple of others from the web
<?php
Replace input.jpg with the name of a jpg image in the same folder as this code and run it.
exec("/usr/bin/convert test.pdf jastest123.jpg");
?>

it convert from jpg to pdf but not pdf to jpg

any help would be appreciated

thanks

Converting from pdf to jpg needs ghostscript. This will be a configuration problem with php. I don't know the answer, but it will be on these forums somewhere.

Yes i have ghostscript installed and it works on command line

all i have read is they need the same path e.g. /usr/bin/

/usr/bin/convert
/usr/bin/gs

but how to I make it work on php

I even tried this from http://www.veryinteractivepeople.com/?p=521
but nothing happens

<?php
ini_set('display_errors', 1);
$pdf='test.pdf';
$quality=90;
$res='300x300';
$exportName="pdf_export_" . time();
$exportPath=realpath(dirname(__FILE__))."/$exportName/fullres/%03d.jpg";

mkdir(realpath(dirname(__FILE__))."/$exportName");
mkdir(realpath(dirname(__FILE__))."/$exportName/fullres");

set_time_limit(900);
exec("'gs' '-dNOPAUSE' '-sDEVICE=jpeg' '-dUseCIEColor' '-dTextAlphaBits=4' '-dGraphicsAlphaBits=4' '-o$exportPath' '-r$res' '-dJPEGQ=$quality' '$pdf'",$output);

for($i=0;$i<count($output);$i++)
echo($output[$i] .'<br/>');
?>


but what else?

thanks

how can I call ghostscript directly

exec("/usr/bin/convert test.pdf jastest123.jpg");

for e.g for gs
exec("/usr/bin/gs test.pdf jastest123.jpg");

Your PHP probably does not find Ghostscript

so how can I fix this? any suggestions

thanks

if i run
convert -list configure

I can see gs under delegates along with freetype fontconfig etc

so that means imagemagick see's gs?

I think your PHP configuration needs to point to GS or at least a version of IM that knows about GS. Search the forum. There may have been topics about this before.

if I can see gs under delegates doesnt that mean IM knows about gs?

No. It means it wants GS.

ok so how do I add it? should I un install both and reinstall? or do just IM only

thanks

If you can uninstall and reinstall I would; I believe Ghostscript should be installed first.

it was a pain to even get this far - is it possible i can add the path to the delegates.xml? where would it be? if I can get the ssh command that would be kool


thanks for you help

If you see gs under delegates from convert -version or convert -list configure, then Imagemagick should be seeing it. That is why it works under the terminal. The problem, I think, is that PHP is not finding it for use with Imagick

so this guy is wrong
