PHP - Watermark And Resizing
Hi I am using this script for water marking images from here
http://911-need-code-help.blogspot.com/2008/11/watermark-your-images-with-another.html which works great. I also tried using this resizer here http://911-need-code-help.blogspot.com/2008/10/resize-images-using-phpgd-library.html because it works great too but trying to get both of them to work together wasn't working for me. The 2 codes are very similar and the farthest I got was being able to produce 2 images at the same time "one watermarked and one resized" I could never actually get it to resize and then watermark. I ended up using another piece of code that i found and and it seems to work great for resizing after the image is watermarked but not before. I keep trying to resize it before the watermark and nothing works for me. Anyone know what i can do to achieve this? or get the 2 scripts in the links above to flow together? Here is my working code for watermarking then resizing. //-------------------------------- // CREATE WATERMARK FUNCTION //-------------------------------- define( 'WATERMARK_OVERLAY_IMAGE', 'http://localhost/d.png' ); define( 'WATERMARK_OVERLAY_OPACITY', 70 ); define( 'WATERMARK_OUTPUT_QUALITY', 90 ); function create_watermark( $source_file_path, $output_file_path ) { list( $source_width, $source_height, $source_type ) = getimagesize( $source_file_path ); if ( $source_type === NULL ) { return false; } switch ( $source_type ) { case IMAGETYPE_GIF: $source_gd_image = imagecreatefromgif( $source_file_path ); break; case IMAGETYPE_JPEG: $source_gd_image = imagecreatefromjpeg( $source_file_path ); break; case IMAGETYPE_PNG: $source_gd_image = imagecreatefrompng( $source_file_path ); break; default: return false; } $overlay_gd_image = imagecreatefrompng( WATERMARK_OVERLAY_IMAGE ); $overlay_width = imagesx( $overlay_gd_image ); $overlay_height = imagesy( $overlay_gd_image ); imagecopymerge( $source_gd_image, $overlay_gd_image, floor(($source_width - $overlay_width) / 2), floor(($source_height - $overlay_height) / 2), 0, 0, $overlay_width, $overlay_height, WATERMARK_OVERLAY_OPACITY ); /* Right corner imagecopymerge( $source_gd_image, $overlay_gd_image, $source_width - $overlay_width, $source_height - $overlay_height, 0, 0, $overlay_width, $overlay_height, WATERMARK_OVERLAY_OPACITY ); */ imagejpeg( $source_gd_image, $output_file_path, WATERMARK_OUTPUT_QUALITY ); imagedestroy( $source_gd_image ); imagedestroy( $overlay_gd_image ); } //-------------------------------- // FILE PROCESSING FUNCTION //-------------------------------- define( 'UPLOADED_IMAGE_DESTINATION', '/xampp/htdocs/admin/original/' ); define( 'PROCESSED_IMAGE_DESTINATION', '/xampp/htdocs/images/' ); define( 'THUMBNAIL_IMAGE_DESTINATION', '/xampp/htdocs/images/' ); function process_image_upload( $Field ) { $temp_file_path = $_FILES[ $Field ][ 'tmp_name' ]; $temp_file_name = $_FILES[ $Field ][ 'name' ]; list( , , $temp_type ) = getimagesize( $temp_file_path ); if ( $temp_type === NULL ) { return false; } switch ( $temp_type ) { case IMAGETYPE_GIF: break; case IMAGETYPE_JPEG: break; case IMAGETYPE_PNG: break; default: return false; } $rand=time(); $dash = "-"; $uploaded_file_path = UPLOADED_IMAGE_DESTINATION . $rand . $dash . $temp_file_name; $processed_file_path = PROCESSED_IMAGE_DESTINATION . $rand . $dash . preg_replace( '/\\.[^\\.]+$/', '.jpg', $temp_file_name ); // $uploaded_image_path = UPLOADED_IMAGE_DESTINATION . $temp_image_name; move_uploaded_file( $temp_file_path, $uploaded_file_path ); $result = create_watermark( $uploaded_file_path, $processed_file_path ); //This is where its does the resize.. include 'test.php'; $image = new Resize_Image; $image->new_width = 350; $image->new_height = 350; $image->image_to_resize = "$processed_file_path"; // Full Path to the file $image->ratio = true; // Keep Aspect Ratio? // Name of the new image (optional) - If it's not set a new will be added automatically $image->new_image_name = 'sunset_wallpaper_thumbnail'; //Path where the new image should be saved.

It was transferred.'; header('Location: gallery.php'); } else{ // echo "There was an error uploading the file, please try again!"; } } ?> I want to watermark a simple TEXT line on some images (ie: "SAMPLE") I have successfully created a working code and using imagettftext and the PHP manual, I have summized that the coordinates 0,0 will essentially place the beginning of the text at the top left corner of my image. This would remain the same regardless of the image size or shape. Are there coordinates that will consistently designate the lower-right corner? Do the coordinates change for horizontals and verticals; large files and small?
I want my watermark password field to say password and not be written in all asterisks. I know that this is because I am using type=password on my input field. I'm not sure how to make the type be text while displaying the password in asterisks. You can see the problem on my site at http://network.jasonbiondo.com Here is the code: Code: [Select] <div id="username"> <input id="username-field" class="loginFields" type="text" name="username" title="Username" value="Username" /> <script type="text/javascript"> //<![CDATA[ document.getElementById('username-field').onfocus = function() { if (this.value == 'Username') this.value=''; }; document.getElementById('username-field').onblur = function() { if (this.value == '') this.value = 'Username'; }; //]]> </script> </div> <div id="password"> <input id="password-field" class="loginFields" type="password" name="password" title="Password" value="Password" /> <script type="text/javascript"> //<![CDATA[ document.getElementById('password-field').onfocus = function() { if (this.value == 'Password') this.value=''; }; document.getElementById('password-field').onblur = function() { if (this.value == '') this.value = 'Password'; }; //]]> </script> </div> what am i doing wrong? my watermark function won't work but i am calling the function right i think. if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { watermark($file_path,$watermark,'png'); mysql_query("INSERT INTO gallery VALUES ('', '$username', '$time', '$caption' , '$file_path' )"); //echo $file_size.' is how big your file is. It was transferred.'; header('Location: gallery.php'); } hi guys i need some help i am trying to create a resized image with a watermark, from an uploaded image.. the image is getting uploaded and resized but the watermark doesnt appear correct. instead of a transparent watermark, there's a black square in it's place. this is my code Code: [Select] $tempfile = $_FILES['filename']['tmp_name']; $src = imagecreatefromjpeg($tempfile); list($origWidth, $origHeight) = getimagesize($tempfile); // creating png image of watermark $watermark = imagecreatefrompng('../imgs/watermark.png'); // getting dimensions of watermark image $watermark_width = imagesx($watermark); $watermark_height = imagesy($watermark); // placing the watermark $dest_x = $origWidth / 2 - $watermark_width / 2; $dest_y = $origHeight / 2 - $watermark_height / 2; imagecopyresampled($src, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, $origWidth, $origHeight); imagealphablending($src, true); imagealphablending($watermark, true); imagejpeg($src,$galleryPhotoLocation,100); // $galleryPhotoLocation is correct. the image gets uploaded successfully.. This topic has been moved to Third Party PHP Scripts. http://www.phpfreaks.com/forums/index.php?topic=319561.0 I had a similar posting regarding positioning of a 2nd watermark on an uploaded video. I have resoled that successfully - thanks again for the help. Now, the watermarks look clear/sharp on a small screen, but when the screen is enlarged the images don't seem as sharp/clear. What is the trick? Solution? Is it to have a large image to begin with? The watermark.png currently is 98px w by 16px h. Here is a portion of the file code:

any assistance is appreciated Hello everyone. I have a report generator for my database and for some reason it is putting a watermark of our company logo in the middle of each page. I have attached the code for the beginning of the script that makes the PDF generator work. Maybe you can find where it should be removed because I am not finding it.

I've got a script that auto-puts watermark on images code: Code: [Select] <?php //get stuff $src = $_SERVER['DOCUMENT_ROOT'].'/'.$_GET['src']; $watermarkSRC = 'img/wm.png'; header('Content-type: image/jpeg'); //create watermark $watermark = imagecreatefrompng($watermarkSRC); //wm dimensions $watermark_width = imagesx($watermark); $watermark_height = imagesy($watermark); $image = imagecreatetruecolor($watermark_width, $watermark_height); //border $border=25; //some crappy logic if(strpos($src,'.gif') !== false) { $image = imagecreatefromgif($src); } elseif(strpos($src,'.jpeg') !== false || strpos($src,'.jpg') !== false) { $image = imagecreatefromjpeg($src); } elseif(strpos($src,'.png') !== false) { $image = imagecreatefrompng($src); } else { exit("Your image is not a gif, jpeg or png image. Sorry."); } //image dimensions $width=ImageSx($image); $height=ImageSy($image); //lets make a border $img_adj_height=$height+$border; $square=imagecreatetruecolor($width,$img_adj_height); //border + image imagecopyresampled($square, $image, 0, 0, 0, 0, $width, $img_adj_height, $width, $img_adj_height); //watermark placement $dest_x = $width - $watermark_width - 5; $dest_y = $img_adj_height - $watermark_height - 5; //border + watermark imagecolortransparent($watermark,imagecolorat($watermark,0,0)); imagecopyresampled($square, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, $watermark_width, $watermark_height); //wrap up imagejpeg($square, "", 100); imagedestroy($image); imagedestroy($watermark); ?> and I want to change it so the watermark will be in a border with the transparent or white background instead of black how can I do that? The web video script that I'm using, and trying to modify, works successfully integrating a watermark in the upper left corner of the video file, (so that when it's downloaded, the watermark stays on the video). In the ffmpeg php file code below, the watermarking starts with this line $watermark_image_full_path = "watermark.png"; at line 275 (out of 504 - about halfway). I am wondering if there might be a way to make the watermark also display briefly in another location on the video again, maybe halfway through, when playing it.

Any guidance with this is appreciated Right now users log in and upload an image to the website. I want every image that is uploaded to be watermarked with a particular logo. Is this possible? Any hints or tips will be appreciated. Thank you. Hi Guys, I'm going to try and watermark my uploaded images with a small logo (placed onto the original image) so they are all watermarked, is there any tutorials anyone can recommend to do this? i can't seem to find any online. thanks for any help guys Graham Hi there, Can you guys/girls tell me if this is even possible: - take pictures with eye-fi card in the camera, which uploads the images to a server - on the server, automatically add a watermark, and post them on 3 different facebookpages Hey guys, i have been creating a profile page for a site i am doing. When i upload an image the profile image gets resized to 150px x 150px (CSS) however you can imagine if the image isnt a perfect size it will be squashed. Is there anyway i can resize the image? so that it doesnt look squashed like keep the full size upload image but pass it through a function before it displays in the profile section? if someone could point me in the right direction that would be awesome. Thanks!! Hi, I have a pretty simple application that allows my users to upload images and i'm able to succesfull upload images to a new dir to be outputted. But as to save on download time and server space is there a simple piece of code I can add to the below code that will resize every image on uploded to 460(w) x 300 (h) from my users Code: [Select] <?php if ((($_FILES["article_image"]["type"] == "image/gif") || ($_FILES["article_image"]["type"] == "image/jpeg") || ($_FILES["article_image"]["type"] == "image/pjpeg")) && ($_FILES["article_image"]["size"] < 5000000)) { move_uploaded_file($_FILES["article_image"]["tmp_name"], "images/" . $_FILES["article_image"]["name"]); } ?> Thanks in advance for any help and suggestions I am absolutley stumped with this: im trying to have PHP get the size of an image that has been uploaded to mySQL, and return it to a certain size, lets say 200X200px. The problems im having to finding an existing script to help me understand - and then fit it into a table? All the help from google searches seem to suggest using software, but i would like to learn how to do this properly. First off the upload script: Code: [Select] <?php error_reporting(E_ALL); ini_set("display_errors", 1); echo '<pre>' . print_r($_FILES, true) . '</pre>'; //This is the directory where images will be saved $target = "/home/users/web/b109/ipg.removalspacecom/images/COMPANIES"; $target = $target . basename( $_FILES['upload']['name']); //This gets all the other information from the form $company_name=$_POST['company_name']; $basicpackage_description=$_POST['basicpackage_description']; $location=$_POST['location']; $postcode=$_POST['postcode']; $upload=($_FILES['upload']['name']); // Connects to your Database mysql_connect("server", "user", "password") or die(mysql_error()) ; mysql_select_db("removalspacelogin") or die(mysql_error()) ; //Writes the information to the database mysql_query("INSERT INTO `Companies` (company_name, basicpackage_description, location, postcode, upload) VALUES ('$company_name', '$basicpackage_description', '$location', '$postcode', '$upload')") ; echo mysql_error(); //Writes the photo to the server if(move_uploaded_file($_FILES['upload']['tmp_name'], $target)) { //Tells you if its all ok echo "The file ". basename( $_FILES['upload']['name']). " has been uploaded, and your information has been added to the directory"; } else { //Gives and error if its not echo "Sorry, there was a problem uploading your file."; } ?> this works great, it uploads the users pictures. This displays them out: Code: [Select] <?php $database="removalspacelogin"; mysql_connect ("server", "user", "password"); @mysql_select_db($database) or die( "Unable to select database"); $result = mysql_query( "SELECT company_name, location, postcode, basicpackage_description, premiumuser_description, upload FROM Companies" ) or die("SELECT Error: ".mysql_error()); $num_rows = mysql_num_rows($result); print "\n\n\nThere are $num_rows records.<P>"; echo "<table><tr><th>Comppany Name</th><th>Location</th><th>Postcode</th><th>Basic Members</th><th>Upgraded Users</th><th>Company Logo</th></tr><tr><td></td><td></td><td></td><td></td><td></td><td></td></tr>";// store the records into $row array and loop through while ( $row = mysql_fetch_array( $result, MYSQL_ASSOC ) ) { // Print out the contents of the entry echo "<tr><td>{$row['company_name']}</td>"; echo "<td>{$row['location']}</td>"; echo "<td>{$row['postcode']}</td>"; echo "<td>{$row['basicpackage_description']}</td>"; echo "<td>{$row['premiumuser_description']}</td>"; echo "<td><img src=\"http://www.removalspace.com/images/COMPANIES{$row['upload']}\" alt=\"logo\" /></td></tr>";} echo "</table>"; ?> Right now all the information in my table is fine except the image coloumn, the images are all the same size as they went in, i'd like them to all be one size so there in a uniformed fashion. But need all the rest of the mySQL table displayed, so how does it fit into my script to display the table? Many thanks!??? Hello: I have a photo uploader in my admin area. First time I tried this so it's new to me. The upload form sends it to the page below, and does the resizing and saving. It seems to automatically resize the photos to make thumbnails, which is really nice. However, I am trying to do 2 things and can't figure it out. 1 - I would like to resize the main photo and not the thumbnail (or just use the thumbnail as the main photo, whichever seems easier). I would like it to be 690px wide but let it scale in proportion to what the height should be (not set a height as I think that's what it is doing now). This is the area where it gets resized: Code: [Select] { $thumbnail_width = 690; $thumbnail_height = (int)(100 * $size[1] / $size[0]); } else { $thumbnail_width = (int)(690 * $size[0] / $size[1]); $thumbnail_height = 100; } Also, the thumbnails are coming out very dark and de-colored. How can I set it so it retains all the color and clarity, but just resizes them? Point I'm trying to do is just resize upon upload, as most of my clients do not and will not resize photos before uploading them, and that means each photo from a digital camera will be about 1.3 MBs, which starts to make a photo gallery page very heavy and clunky. This is the full code, if it will help: Code: [Select] <?php // initialization $result_final = ""; $counter = 0; // List of our known photo types $known_photo_types = array( 'image/pjpeg' => 'jpg', 'image/jpeg' => 'jpg', 'image/gif' => 'gif', 'image/bmp' => 'bmp', 'image/x-png' => 'png' ); // GD Function List $gd_function_suffix = array( 'image/pjpeg' => 'JPEG', 'image/jpeg' => 'JPEG', 'image/gif' => 'GIF', 'image/bmp' => 'WBMP', 'image/x-png' => 'PNG' ); // Fetch the photo array sent by preupload.php $photos_uploaded = $_FILES['photo_filename']; // Fetch the photo caption array $photo_caption = $_POST['photo_caption']; while( $counter <= count($photos_uploaded) ) { if($photos_uploaded['size'][$counter] > 0) { if(!array_key_exists($photos_uploaded['type'][$counter], $known_photo_types)) { $result_final .= "File ".($counter+1)." is not a photo<br />"; } else { mysql_query( "INSERT INTO gallery_photos(`photo_filename`, `photo_caption`, `photo_category`) VALUES('0', '".addslashes($photo_caption[$counter])."', '".addslashes($_POST['category'])."')" ); $new_id = mysql_insert_id(); $filetype = $photos_uploaded['type'][$counter]; $extention = $known_photo_types[$filetype]; $filename = $new_id.".".$extention; mysql_query( "UPDATE gallery_photos SET photo_filename='".addslashes($filename)."'

Hello, Does anyone have any knowledge of resizing an image in PHP keeping contraints on the dimensions? If not, any tutorial websites any knows? George. Hi all I am trying to write a piece of code that will resize and image to fit in a canvas 300 by 300 pixels and centre horizontally and vertically. Here's my code: Code: [Select] $imagelarge = $_FILES['image']['tmp_name']; $imagelargemain = $_FILES['image']['name']; $src = imagecreatefromjpeg($imagelarge); list($width,$height)=getimagesize($imagelarge); $newwidth=300; $newheight=($height/$width)*$newwidth; $center_x = 300/300; $center_y = (300/2)-($newheight/2); $tmp=imagecreatetruecolor(300,300); $white = imagecolorallocate($tmp, 255, 255, 255); imagefill($tmp, 0, 0, $white); imagecopyresampled($tmp,$src,$center_x,$center_y,0,0,$newwidth,$newheight,$width,$height); This works ok but if the user uploads a very thin and tall image it only shows the middle? Please help! Many thanks Pete As a point of curiosity, I am seeking some clarification. I have developed code to resize an image, thus reducing the file size by a percentage of it's original. My first question is, what exactly is being done to the file? I understand that some data is being removed (or condenced) but how does this effect the image when compared with the original on a webpage? Next, what should my expectation be if I wanted to reverse the process? If I am 'shrinking' an image for a faster upload speed and reduced storage capacity, how successful will I be if I wanted to 'restore' the file size before printing a physical photograph? Will this provide a 'better' end result?
