I’ve installed ImageMagick on OS X using macports (I don’t think these makes any difference but just in case)
I use the following:
$im = new imagick($src . '[0]');
$im->setImageFormat('png');
header("Content-Type: image/png" );
echo $im;
and I get a nice conversion of a pdf to a png.
Every time I do that however, I end up with a file like:
magick-23Iwt3tG
in /private/var/tmp. They do not seem to delete automatically.
Do I need to delete these manually or is there an option I can set to have them automatically deleted? (I don’t want to end up with tons of these files hanging around)
The contents of /private/var/temp can be safely deleted but are not included in the /etc/rc.cleanup and /etc/weekly scripts which remove temporary files.
You can either do it manually or there is a script here which should do it for you.
