Imagick::adaptiveResizeImage

(PECL imagick 2.0.0)

Imagick::adaptiveResizeImageAdaptively resize image with data dependent triangulation

说明

bool Imagick::adaptiveResizeImage ( int $columns , int $rows [, bool $fit=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. This method is available if Imagick has been compiled against ImageMagick version 6.2.9 or newer.

参数

columns

The number of columns in the scaled image.

rows

The number of rows in the scaled image.

fit

Whether to fit the image inside a bounding box.

返回值

Returns TRUE on success.

错误/异常

Throws ImagickException on error.

更新日志

版本 说明
2.1.0 Added optional fit parameter.
2.1.0 This method now supports proportional scaling. Pass zero as either parameter for proportional scaling.

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;
?>
