water mark trouble

[corillo181]

i took this code of a site, becuase i'm a rush to create a water mark,

but as simple as it looks when the images is save, it saves

as resource id#

<?php  
$watermark = imagecreatefrompng('logo2.png');

$watermark_width = imagesx($watermark);  
$watermark_height = imagesy($watermark);

$image = imagecreatetruecolor($watermark_width, $watermark_height);  
$image = imagecreatefromjpeg('eaa02aa217e7c72264582687e25183cb.jpg');  
$size = getimagesize('eaa02aa217e7c72264582687e25183cb.jpg');  

$dest_x = $size[0] - $watermark_width - 5;  
$dest_y = $size[1] - $watermark_height - 5;

imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);  
imagejpeg($image,'new_'.$image,100);  
//imagedestroy($image);  
//imagedestroy($watermark);

?>

You are saving the file name as the image resource on this line:

 

imagejpeg($image,'new_'.$image,100); 

[schilly]

you need to open a new file and add that resource into the imagejpeg line

imagejpeg($image_resource,$file_resource,$quality);

alright i changed it a name but now the png that is been applied to the image does no contain it's transparency it turns white.

<?php  
$watermark = imagecreatefrompng('logofotos.png');

$watermark_width = imagesx($watermark);  
$watermark_height = imagesy($watermark);

$image = imagecreatetruecolor($watermark_width, $watermark_height);  
$image = imagecreatefromjpeg('e47ade7dacd19dce6251270cd5f5e83c.jpg');  
$size = getimagesize('e47ade7dacd19dce6251270cd5f5e83c.jpg');  

$dest_x = $size[0] - $watermark_width - 5;  
$dest_y = $size[1] - $watermark_height - 5;

imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);  
imagejpeg($image,'new_image.jpg',100);  
//imagedestroy($image);  
//imagedestroy($watermark);

?>

so no help here?

You usage of

 

imagecopymerge is redundant

 

try just using

 

imagecopy($image, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height);

 

see if that preserves the alpha values

that works, thank you.
