Objective is to integrate khtml2png2 into a WordPress template post loop. Captures need to cached. If script is too burdensome on server I’d like the ability to run via command-line or admin interface feeding it with url batch? The below code was an unsuccessful attempt:
<div class=”khtml2png2″>
<?php
$mykey_values = get_post_custom_values(‘web’);
foreach ( $mykey_values as $key => $value ) {
$output_file = $value.”.png”;
if (!file_exists($output_file)){
$cmd = “khtml2png2 –display :2″.
” –width 1024″.
” –height 768″.
” –time 45″.
” –disable-java”.
” –disable-plugins”.
” –disable-redirect”.
” –disable-popupkiller”.
” –nograb”.
” http://”.$value.
” “.$output_file;
echo $value.” <br/ >”;
echo $cmd.” <br/ >”;
exec(“$cmd”);
while(!file_exists($output_file)) { sleep(1); }
echo ‘<img src=”‘.$value.’.png” name=”‘.$value.'” alt=”‘.$value.'” id=”ThumbUrl”> ‘;
}else{
echo ‘<img src=”‘.$value.’.png” name=”‘.$value.'” alt=”‘.$value.'” id=”ThumbUrl”> ‘;
}
}
?>
</div>
