January 01, 2018

Step-1. Create an index.php file inside your project folder

<?php
include('header.php');
include('functions.php');?>
<title> PHPWRITTER-WATERMARK </title>
<?php include('container.php');?>
<div class="container">
 <h2> PHPWRITTER-WATERMARK-IMAGES</h2> 
 <br>
 <br>
 <form action="" method="post" enctype="multipart/form-data">  
 <input type="file" name="image" value=""><br>
 <select name="image_upload">
 <option value="">Water Mark Type</option>
 <option value="text_watermark"> PHPWRITTER-Text-Mark</option>
 <option value="image_watermark"> PHPWRITTER-Image-Mark</option>
 </select>
 <input type="submit" value="Upload"><br>
 </form> 
 
  //http://phpwritter.blogspot.in//
  <?php
 if(isset($_FILES['image']['name'])){
 switch($_FILES['image']['type']){
   
        case 'image/jpeg':   
 case 'image/jpg':
   
 if(getimagesize($_FILES['image']['tmp_name']) < (1024*1024*1024*1024)){
 echo 'Image size is greater than 2MB';
 } elseif(empty($_POST['image_upload'])){
 echo 'Please select watermark type';
 } else {
     
 list($txt, $ext) = explode(".", $_FILES['image']['name']);
 $file_name = "images/watermark.".$ext;
 $upload = copy($_FILES['image']['tmp_name'], $file_name);
 if($upload == true){
      
 if($_POST['image_upload'] == 'text_watermark'){
      
 $watermark = "phpwritter.blogspot.in";
 addTextWatermark($file_name, $watermark, $file_name);       
 } elseif($_POST['image_upload'] == 'image_watermark'){
    
 $WaterMark = 'watermark.png';
 addImageWatermark ($file_name, $WaterMark, $file_name, 50);
 }
 echo '<br><img src="'.$file_name.'" class="preview" width="1000"><br>';
 } else {
 echo 'Error uploading image';
     }
    }
   break;
   default:
   echo 'Please select jpeg or jpg type file for upload';
  }
 }
 ?> 
 <br>
 <br>
 <div style="margin:10px 0px 0px 0px;">
  <a class="btn btn-default read-more" style="background:#ddd;color:white" href="" title="">Submit</a>   
 </div>  
</div>

Step-2. Create function.php file and Copy this Code or Paste Function .php File

<?php
function addTextWatermark($src, $watermark, $save=NULL) {
 list($width, $height) = getimagesize($src);
 $image_color = imagecreatetruecolor($width, $height);
 $image = imagecreatefromjpeg($src);
 imagecopyresampled($image_color, $image, 0, 0, 0, 0, $width, $height, $width, $height);
 $txtcolor = imagecolorallocate($image_color, 255, 255, 255);
 $font = 'MONOFONT.TTF';
 $font_size = 50;
 imagettftext($image_color, $font_size, 0, 50, 150, $txtcolor, $font, $watermark);
 if ($save<>'') {
 imagejpeg ($image_color, $save, 100);
 } else {
  header('Content-Type: image/jpeg');
  imagejpeg($image_color, null, 100);
 }
 imagedestroy($image);
 imagedestroy($image_color);
}
//http://phpwritter.blogspot.in//

function addImageWatermark($SourceFile, $WaterMark, $DestinationFile=NULL, $opacity) {
 $main_img = $SourceFile;
 $watermark_img = $WaterMark;
 $padding = 5;
 $opacity = $opacity;

//http://phpwritter.blogspot.in//

$watermark = imagecreatefrompng($watermark_img);
 $image = imagecreatefromjpeg($main_img);
 if(!$image || !$watermark) die("IMAGE IS NOT WORKING");
 $watermark_size = getimagesize($watermark_img);
 $watermark_width = $watermark_size[0];
 $watermark_height = $watermark_size[1];
 $image_size = getimagesize($main_img);
 $dest_x = $image_size[0] - $watermark_width - $padding;
 $dest_y = $image_size[1] - $watermark_height - $padding;
 imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, $opacity);
 if ($DestinationFile<>'') {
 imagejpeg($image, $DestinationFile, 100);
 } else {
  header('Content-Type: image/jpeg');
  imagejpeg($image);
 }
 imagedestroy($image);
 imagedestroy($watermark);
}
