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

说明

bool Imagick::adaptiveResizeImage ( int $columns , int $rows )
Warning

本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

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.

参数

columns

The number of columns in the scaled image.

rows

The number of rows in the scaled image.

返回值

Returns TRUE on success.

错误／异常

Throws ImagickException on error.

范例

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;
?>
