I wrote a script for this; it's designed to run from the command line in
*nix, but can be triggered via exec():
Usage: ./pdf2thumb.php "source_dir" "out_dir"
[code]
#!/usr/local/bin/php
<?
function getDirFiles($dirPath){
$filesArr=array("");
if ($handle = opendir($dirPath)){
while (false !== ($file = readdir($handle)))
if ($file != "." && $file != ".."){$filesArr[] = trim($file);}
closedir($handle);}
return $filesArr;
}
function usage(){
echo("USAGE: pdf2thumb source_folder_path
<destination_folder_path>\n\n");
exit;
}
if(!isset($argv[1])){usage();}
substr($argv[1],-1)=="/"?$path=$argv[1]:$path=$argv[1]."/";
isset($argv[2])?$dest_path=$argv[2]:$dest_path=$path;
substr($dest_path,-1)=="/"?$dest_path=$dest_path:$dest_path.="/";
$total_time=0;
$total_files=0;
if(!file_exists($dest_path)){`mkdir $dest_path`;}
$files=getDirFiles($path);
for($i=0;$i<count($files);$i++){
if(substr($files[$i],-3)=="pdf"){
echo("Converting ".$files[$i]."... ");
$time_start = microtime(true);
$old_name=$path.$files[$i];
$new_name=$dest_path.str_replace(".pdf",".jpg",$files[$i]);
`/usr/bin/convert '$old_name' -thumbnail 240x160 '$new_name'`;
$time_end = microtime(true);
$convert_time=round($time_end-$time_start,2);
echo("Done. ($convert_time seconds)\n");
$total_time+=$convert_time;
$total_files++;
}
}
echo("\n---------------------------------------------------\n");
echo("$total_files files converted in ".round($total_time/60,2)."
$minutes (AVG: ".round($total_time/$total_files,2)."s)\n\n");
?>
[/code]

You would haven't happen to have an example? I am new to imagemagick. Any
help would be greatly appreciated.

Subject: PDF Thumbnails
I give my users an option to upload pdf files to my site and
would like them
to see a thumbnail view of the file once uploaded. Has anyone
heard of a way
how to do this?
The 'convert' function of ImageMagick will do it.
