Imagick::adaptiveResizeImageAdaptively resize image with data dependent triangulation

Описание

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. Този метод съществува ако Imagick е била компилирана за версия 6.2.9 на ImageMagick или по-нова.

Параметри

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.

Връщани стойности

Грешки/Изключения

Примери

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;
?>
