CKFinder loose png transparency on thumbnails (PHP)

[Benoît Geeraerts]

I don't know if it's clear enough on the screenshot but the "buy" button (3rd image) should have transparent rounded borders but they appear black. This is caused by imagecopyresampled not keeping trancparency on png.

Here is a fix for this : in CommandHandler/Thumbnails.php

add this code after the line

$oThumbImage = imagecreatetruecolor($oSize["Width"], $oSize["Height"]); 

(line 237)

if($sourceImageAttr['mime'] == 'image/png'){
imagecolortransparent($oThumbImage, imagecolorallocate($oThumbImage, 0, 0, 0));
imagealphablending($oThumbImage, false);
imagesavealpha($oThumbImage, true);
} 

Regards,

Ben.

Looks like my fix does not work properly, sorry.

May be related to the $quality test on fastImageCopyResampled function.

Here is the buy button so you can test.
