Watermarking with GD

[graham23s]

Hi Guys,

 

i'm trying to watermark my images with text i have this:

 

<?php
function resize_image($upload_directory, $new_image_name)
{
  // original image location //
  $original_image = $upload_directory;
  
  // set up a canvas sizes //
  $canvas_width = 65;
  $canvas_height = 65;
  
  // create the canvas //
  $canvas = imagecreatetruecolor($canvas_width, $canvas_height);
  
  // make the background color white //
  $white_background = imagecolorallocate($canvas, 255, 255, 255);
  
  // change the background to white //
  imagefill($canvas, 0, 0, $white_background);
  
  // get the image height and width //
  list($image_width, $image_height) = getimagesize($upload_directory);
  
  #########################################
  // RATIO CALCULATIONS //
  $ratio = $image_width / $image_height;
  
    if ($ratio > 1 )
    {
  
  	$new_image_width = 65;
	$new_image_height = 65 / $ratio;
  
     } else {
   
   	$new_image_width = (float) 65 * $ratio;
	$new_image_height = 65;
   
  }
  // RATIO CALCULATIONS //
  #########################################
  
  // store original into memory //
  $original_image = imagecreatefromjpeg($original_image);
  
  // ========================================= //
  // WATERMARK CODE!
  // ========================================= //
  $textcolor = imagecolorallocate($im, 0, 0, 255);

  // write the string at the top left
  imagestring($original_image, 5, 0, 0, "Hello world!", $textcolor);  
  // ========================================= //
  // WATERMARK CODE!
  // ========================================= //
  
  // copy the original image onto the canvas canvas, original and top/left co-ordinates //
  imagecopyresampled($canvas, $original_image, 0,0,0,0, $new_image_width, $new_image_height, $image_width, $image_height);
  
  // thumbnail name //
  $new_thumbnail_name = "thumb-$new_image_name";
  
  // save the thumbnail in the thumbs folder //
  if(imagejpeg($canvas, "products/thumbnails/$new_thumbnail_name", 100))
  {
   return("$new_thumbnail_name");
  }
  
  // destroy the images in memory //
  imagedestroy($original_image);
  imagedestroy($canvas);  
  
} // end function //
?>

 

i highlighted where i have put the watermarking code but its not doing anything! can anyone see the problem?

 

cheers guys

Is the resulting image just the same without the watermark?

 

Did you try imagefill() after imagecopyresampled()?
