Example#1 Using Imagick::adaptiveResizeImage()
Resize an image to a standard size for the web. This method works best when resizing to a size only slightly smaller than the previous image size.
<?php
header('Content-type: image/jpeg');
$image = new Imagick('image.jpg');
$image->adaptiveResizeImage(1024,768);
echo $image;
?>
