Imagick::adaptiveResizeImage — Adaptively resize image with data dependent triangulation
Beschreibung
Adaptively resize image with data-dependent triangulation. Avoids blurring across sharp color changes. Most useful when used to shrink images slightly to a slightly smaller "web size"; may not look good when a full-sized image is adaptively resized to a thumbnail. Diese Funktion ist verfügbar, wenn Imagick gegen die ImageMagick Version 6.2.9 oder höher kompiliert wurde.

Beispiele
Beispiel #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;
?>
