Padding thumbnail with color
I know, it’s been a while since I last blogged. This is because a lot of things are happening in my personal life. I recently relocated to London from Finland and started a new job. Things are quite busy but I will try to post an example now and then. In the meanwhile I would like to hear about sites using Imagick, so if your project is not super secret please post an url and maybe a small explanation what you’re doing with Imagick on the site. This is purely for my personal interest.
Anyway, to the point. Today’s example originates from a question asked by a user. How do I thumbnail the image inside given dimensions proportionally and fill the “blank” areas with a color ? Well, the answer is here
The code is for Imagick 2.1.0 but adapting to older versions should not be hard.
-
< ?php
-
/* Define width and height of the thumbnail */
-
$width = 100 ;
-
$height = 100 ;
-
-
/* Instanciate and read the image in */
-
$im = new Imagick( "test.png" ) ;
-
-
/* Fit the image into $width x $height box
-
The third parameter fits the image into a "bounding box" */
-
$im->thumbnailImage( $width, $height, true ) ;
-
-
/* Create a canvas with the desired color */
-
$canvas = new Imagick() ;
-
$canvas->newImage( $width, $height, ’pink’, ’png’ ) ;
-
-
/* Get the image geometry */
-
$geometry = $im->getImageGeometry() ;
-
-
/* The overlay x and y coordinates */
-
$x = ( $width - $geometry[’width’] ) / 2 ;
-
$y = ( $height - $geometry[’height’] ) / 2 ;
-
-
/* Composite on the canvas */
-
$canvas->compositeImage( $im, imagick: :COMPOSITE_OVER, $x, $y ) ;
-
-
/* Output the image*/
-
header( "Content-Type : image/png" ) ;
-
echo $canvas ;
-
-
?>
