Imagick::adaptiveResizeImage — Adaptively resize image with data dependent triangulation
$columns
, int $rows
[, bool $bestfit = FALSE
[, bool $legacy = FALSE
]] ) : boolAdaptively 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. �˷�����Imagick����ImageMagick 6.2.9���ϰ汾����ʱ���á�

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;
?>
