Hi All,

I'm working on a service page for the site admins. They will be able to change the uploaded image's watermark on this CMS page

So I included the watermark size (percentage) and the image to service page:

class Szerviz extends Page {

public static $db = array(
'LogoPercent' => 'Int',

public static $has_one = array(
'WatermarkFile' => 'Image',

From the ImageDecorator.php I can reach only the image size, but the image not. My code:

class ImageDecorator extends DataObjectDecorator {

function onAfterWrite(){
$logo_percent=DataObject::get_one('Szerviz')->LogoPercent; //works

//it doesn't work:
$watermark = imagecreatefrompng(str_replace('/','\\',Director::baseFolder()

What's wrong?

Although, given the context, I'd probably use WatermarkFile()->getFullPath();
