(PECL imagick 2.0.0)
Imagick::adaptiveResizeImage — Adaptively resize image with data dependent triangulation
설명
$columns
, int $rows
[, bool $bestfit = false
] )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. 이 메쏘드는 Imagick을 ImageMagick 6.2.9 이상으로 컴파일 했을 때만 사용할 수 있습니다.
Note: The behavior of the parameter
bestfitchanged in Imagick 3.0.0. Before this version given dimensions 400x400 an image of dimensions 200x150 would be left untouched. In Imagick 3.0.0 and later the image would be scaled up to size 400x300 as this is the "best fit" for the given dimensions. Ifbestfitparameter is used both width and height must be given.

예제
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;
?>
