This original script was written by Mikko and can be found here: http://valokuva.org/?cat=1&paged=2 I modified the script so that it would watermark all images in a directory. This doesn't actually put a permanent mark on the image. You only see the watermark when you view the image with your browser. If you move the image to a another directory you won't see the watermark anymore. First create a .htaccess file in your image directory and add this to it:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule \.(gif|jpeg|jpg|png)$ watermarker.php [QSA,NC] Next create a file named watermarker.php and add this script to it: <?php
/* set image path */
$img = $_SERVER['DOCUMENT_ROOT'].$_SERVER['REQUEST_URI'];
/* Read the image in. This image will be watermarked. */
$image = new Imagick($img);
/* get and set image format */
$type = strtolower($image->getimageformat());
$image->setimageformat($type);
/* get image width and height */
$w = $image->getimagewidth();
$h = $image->getimageheight();
/* The text to write on the mark */
$text = "byrondallas.heliohost.org";
/* This object will hold the font properties */
$draw = new ImagickDraw();
/* Setting gravity to the center changes the origo
where annotation coordinates are relative to */
$draw->setGravity(Imagick::GRAVITY_CENTER);
/* Use a custom truetype font or server font */
$draw->setFont("Utopia-Bold-Italic");
/* Set the font size */
$draw->setFontSize(26);
/* Create a new imagick object */
$im = new imagick();
/* Get the text properties */
$properties = $im->queryFontMetrics($draw, $text);
/* Region size for the watermark.
Add some extra space on the sides */
$watermark['w'] = intval($properties["textWidth"] + 10);
$watermark['h'] = intval($properties["textHeight"] + 10);
/* Create a canvas using the font properties.
Add some extra space on width and height */
$im->newImage($watermark['w'], $watermark['h'],
new ImagickPixel("transparent"));
/* Get a region pixel iterator to get the pixels in the watermark area */
$it = $image->getPixelRegionIterator(0, 0, $watermark['w'], $watermark['h']);
$luminosity = 0;
$i = 0;
/* Loop trough rows */
while($row = $it->getNextIteratorRow())
{
/* Loop trough each column on the row */
foreach ($row as $pixel)
{
/* Get HSL values */
$hsl = $pixel->getHSL();
$luminosity += $hsl['luminosity'];
$i++;
}
}
/* If we are closer to white, then use black font and
the other way around */
$textColor = ( ( $luminosity / $i )> 0.5 ) ?
new ImagickPixel("black") : new ImagickPixel("white");
/* Use the same color for the shadow */
$draw->setFillColor($textColor);
/* Use png format */
$im->setImageFormat("png");
/* Annotate some text on the image */
$im->annotateImage($draw, 0, 0, 0, $text);
/* Clone the canvas to create the shadow */
$watermark = $im->clone();
/* Set the image bg color to black. (The color of the shadow) */
$watermark->setImageBackgroundColor($textColor);
/* Create the shadow (You can tweak the parameters
to produce "different" kind of shadows */
$watermark->shadowImage(80, 2, 2, 2);
/* Composite the text on the background */
$watermark->compositeImage($im, Imagick::COMPOSITE_OVER, 0, 0);
/* get width and height of watermark image */
$ww = $im->getimagewidth();
$wh = $im->getimageheight();
/* Composite the watermark on the image to the bottom righthand corner. Use 0, 0 for top left */
$image->compositeImage($watermark, Imagick::COMPOSITE_OVER, $w-$ww, $h-$wh);
/* Display the results */
header("Content-Type: image/$type");
echo $image;
?> That's it. Now anytime somebody viesw one of your images they will see a watermark similar to the ones you see on my two examples: http://byrondallas.heliohost.org/images/fs/little-cowboy.jpg http://byrondallas.heliohost.org/images/fs/carmen_electra_106.jpg btw, this only works on the Stevie server. Johnny doesn't have the Imagick Class.
