imagecreatefrompng looses transparency.

[lynxus]

Hi Guys,

 

I have a script that will display an image based on what the user selected in a DB.

 

so for instance.

 

a user will have <img src="http://blaa.com/image.php?siteid=1234">

 

Now my

image.php will

 

<?
// do lost of other error checking etc
// add their ip and time to a DB for visitor tracking.

// now show the user a image

$style = $_GET['siteid'];

   $image = imagecreatefrompng('http://status.imsupporting.com/'.$style.'off.png');

}
}

// and now... we display the image
imagepng($image);
imagedestroy($image);

?>

this doesn't preserve the transparency , Is there a better way to do all this?

Good stuff thanks

 

all i did was add

 

imagealphablending($image, true); // setting alpha blending on

imagesavealpha($image, true); // save alphablending setting (important)

 

just above

imagepng($image);

imagedestroy($image);

 

 

Thanks
