wanna see something cool?

GetIconInfo($index);
$icons[$index]['width'] = $icon['Width'];
$icons[$index]['bitcount'] = $icon['BitCount'];
}
// sort by width, then bitcount (ascending). you can change the priority if you like by switching them around above
asort($icons);
// get the key of the last icon (highest quality) in the sorted list
$best = end(array_keys($icons));
// now make a png
if(!($png=$ico->GetIcon($best))) die(“Could not load ICO.”);
else {
header(“Content-Type: image/png”);
imagepng($png);
}
// win!
?>

< ?php
error_reporting(0);
require 'class.ico.php';
// load the .ico
$ico = new Ico('favicon.ico');
// now we're going to find the highest quality icon! first we need to know about each icon's image quality...
for($index = 0; $index TotalIcons(); $index++){
$icon = $ico->GetIconInfo($index);

Great! keep the good work!

For the convenient of others, here’s a quote from the first post:
————
Here’s how you use the class:
GetIcon(0))) die(“Could not load ICO.”);
else {
header(“Content-Type: image/png”);
imagepng($r);
}
?>
————

And I’ve modified a bit your class, sometimes I just want to get the best quality icon (that’s usually the last icon in the file) so I’ve replaced this:
———–
function &GetIcon($index) {
if (!isset($this->formats[$index])) {
———–
with this:
———–
function &GetIcon($index=null) {
if (is_null($index)) {
$index = count($this->formats)-1;
}
if (!isset($this->formats[$index])) {
———–
so I can omit the $index parameter and get the best icon (assuming he’s the last one)

Good luck everyone!
