Imagemagick and php

Anon

I am calling imagemagick from php, and using it to create custom sized thumbnails of a image.

I want to avoid saving the thumbnail to disk, and send it right to the browser.
I have something similar to this:

<?
$command = "/usr/local/bin/convert -geometry ".$width."x /tmp/foo.jpg";
$command ; // backtick command

$expired = gmdate("D, d M Y H:i:s",(time() + 3600)." GMT");
header("Expires: $expired");
header("Content-type: image/jpeg");

readfile("/tmp/foo.jpg");

I want to avoid writing out foo.jpg, then reading it back it. Is there anyway to send the output from convert directly to the browser?

thanks

assuming imagemagick can output to the prompt try the passthru() command.

<?
$command = "/usr/local/bin/convert -geometry ".$width."x /tmp/foo.jpg jpeg:-";
$imagedata = $command;

$expired = gmdate("D, d M Y H:i:s",(time() + 3600)." GMT");
header("Expires: $expired");
header("Content-type: image/jpeg");

print $imagedata;

The jpeg:- at the end of the convert command tells convert to print the thumbnail to stdout, so you can put it into $imagedata, and then print $imagedata later on.

I was just passing by and noticed this thread. Thank you! This is the exact information I was looking for! After successfully setting up ImageMagick, this example worked perfectly for me. Thanks, Nick.
