need help

[bulldogric]

I run a Web site, and a year ago I paid someone to create a custom Flash gallery. All in all, it works pretty well. But there are some problems, and the person who did the work no longer replies to my email.

 

With the help of my host provider and some online research, I have it close to working the way it should. The biggest issue is that a script that processes the images is supposed to place a watermark, but isn't. It is creating a spot for the watermark, but it isn't putting in the actual watermark.

 

I have almost no knowledge of PHP, and my host provider said they can't help me with this problem, so I'm wondering if anyone out there can tell me what the problem is.

 

Here is the part of the script that deals with the watermark.

 

------------------------------------------------------------------

 

if($pieces[4]=="slides"){

          $transparency = 40;                                    // watermark's transparency (0-100)

          $watermark = imagecreatefrompng('msc_watermark.png');    // watermark stored in admin folder placed in variable $watermark

          $watermark_width = imagesx($watermark);

          $watermark_height = imagesy($watermark);

          $image = imagecreatefromjpeg($imageDestination);    // store image that we want to process in variable $image

          $size = getimagesize($imageDestination);

          $dest_x = $size[0] - $watermark_width - 100;

          $dest_y = $size[1] - $watermark_height - 100;

          imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 40);

          imagejpeg($image, $imageDestination);

          imagedestroy($image);

          imagedestroy($watermark);

          echo "Watermark created on ".$imageDestination."<br />";

 

------------------------------------------------------------------

 

The watermark is in the admin folder and is named msc_watermark.png

The rest of the script appears to work fine.

 

Any help would be greatly appreciated. Thank you.

<?php
$watermark = imagecreatefrompng('/gallery_collegewomen2006/admin/msc_watermark.png');    
?>

I tried that and got ...

 

---------------------------------------

functions.php is the PHP script with the watermark information in it

Basicly your issue comes down to the fact that you need the real path of the image from your script, or else it will not work. I do not know if the image is even where you are telling me, because it is your server and I am guessing.

But try this: (Note: Please Convert the (xxxxx) back to the correct directory.)

<?php
$real_file=is_file('/home/(xxxxx)/public_html/gallery_collegewomen2006/admin/msc_watermark.png');
if($real_file===TRUE) {
    $watermark = imagecreatefrompng('/home/(xxxxx)/public_html/gallery_collegewomen2006/admin/msc_watermark.png');    
}
//Option 2: If you get real desperate we can also look into the realpath() function.
$real_path=realpath('msc_watermark.png');
$watermark = imagecreatefrompng($real_path);
?>

See if this works..

 

<?php
$watermark = imagecreatefrompng(__PATH__.'/gallery_collegewomen2006/admin/msc_watermark.png');    
?>

Thanks for the help!

 

No errors using this, but still the same problem -- a box where the watermark should be, but no watermark.

 

----------------------------------

 

$transparency = 100; // watermark's transparency (0-100)

$real_file=is_file('/home/madisons/public_html/gallery_collegewomen2006/admin/msc_watermark.png');

if($real_file===TRUE)

    $watermark = imagecreatefrompng('/home/madisons/public_html/gallery_collegewomen2006/admin/msc_watermark.png');   

$watermark_width = imagesx($watermark);

$watermark_height = imagesy($watermark);

$image = imagecreatefromjpeg($imageDestination); // store image that we want to process in variable $image

$size = getimagesize($imageDestination);

$dest_x = $size[0] - $watermark_width - 100;

$dest_y = $size[1] - $watermark_height - 100;

imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 40);

imagejpeg($image, $imageDestination);

imagedestroy($image);

imagedestroy($watermark);

echo "Watermark created on ".$imageDestination."<br />";

 

----------------------------------

Got the same thing with Option 2.

 

I also tried the one with __PATH__., but I got errors

 

Here is the watermark

http://www.madisonsoccercentral.com/gallery_collegewomen2006/admin/msc_watermark.png

 

Here is the gallery (click on the pix folder for Option 1 result, test folder for Option 2 result)

http://www.madisonsoccercentral.com/gallery_collegewomen2006/

 

 

Is there other information I can provide that might help find the problem?

 

[WolfRage]

Try this let me know the results.

Replace:

<?php
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 40);
?>

With:

<?php
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);
?>

[bulldogric]

OK, tried it. Now the box is black.

 

I also changed the transparency to 40 ... still get a black box.

[WolfRage]

The reason is that jpeg does not support alpha color transparency, so the image will have to be png format, if that is OK with you then do this.

Replace:

<?php
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 40);
imagejpeg($image, $imageDestination); 
?>

With:

<?php
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 40);
imagepng($image, $imageDestination); 
?>

This should solve your problem.

[bulldogric]

unfortunately, this doesn't work -- no error messages, but the photos won't show in the gallery. they're all .jpg

 

what if the watermark was a .jpg? would that work?

[bulldogric]

But as I re-read this, .jpg can't do transparency.

 

I know I've seen it work properly, just don't know how it was done.

[WolfRage]

jpeg does not support Alpha transparancy, but the function will still fade the image, that is the number 40 in action Thus you still get a watermark affect. Although perhaps not ideal.

So make both images jpeg and use that correct imagejpeg() function, then merge them with the same parameters using imagecopymerge() . Let me know how it turns out.

[bulldogric]

That fixed it! Just have to darken up the watermark!

 

Thanks so much -- I greatly appreciate your help.

Not a Problem, Please mark this solved.
