Imagick::adaptiveResizeImage — Adaptively resize image with data dependent triangulation

说锟斤拷

Imagick::adaptiveResizeImage ( int $columns , int $rows [, bool $bestfit = FALSE [, bool $legacy = FALSE ]] ) : bool

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. 锟剿凤拷锟斤拷锟斤拷Imagick锟斤拷锟斤拷ImageMagick 6.2.9锟斤拷锟较版本锟斤拷锟斤拷时锟斤拷锟矫★拷

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;
?>
