problem in imagecopymerge

[like_php]

hello

I try to copy, resize the photo and add my logo as a watermark on it.

I success for copy and resize but on add logo I failed.

this is my code:

$original_name=$_FILES['original_file']['name'];
$preview_folder="/home/site/public_html/abs/preview/";
$preview_folder=$preview_folder.basename($original_name);
// The file
$filename = "$preview_folder";

// Set a maximum height and width
$width = 400;
$height = 400;

// Content type
header('Content-type: image/jpeg');

// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

// Output
imagejpeg($image_p, "$preview_folder");
//water mark
$image2=imagecreatefromgif("/home/absim/public_html/abs/images/logo.gif");
imagecopymerge($image, $image2, 0,0,0, 0, $width, $height, 100);

didnt give me any error but water mark is not exist

hope can you help

I'm a bit confused. You first resample the image, but then you output it to a file before the imagecopymerge() function is called.

So basically, the image is outputted before any of the watermarking is done.

thanks for replay

I changed it to :

$preview_folder="/home/absim/public_html/abs/preview/";
$preview_folder=$preview_folder.basename($original_name);
// The file
$filename = "$original_folder";

// Set a maximum height and width
$width = 400;
$height = 400;

// Content type
header('Content-type: image/jpeg');

// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
//watermark
$image2=imagecreatefromgif("/home/absim/public_html/abs/images/logo.gif");
imagecopymerge($image, $image2, 0,0,0, 0, $width, $height, 100);
// Output
imagejpeg($image_p, "$preview_folder");

but still the same

Ok, now look at the flow of things.

You resample the image, and store the newly sampled resource in $image_p.

Then, you merge the watermark with $image.

Finally, you output $image_p to a file.

Notice the problem? The watermark isn't merged with the new resource (that eventually gets outputted to file).
