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

Description

bool Imagick::adaptiveResizeImage ( int $columns , int $rows [, bool $fit ] )

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.

Valeurs de retour

Exemples

Exemple #1 Using Imagick::adaptiveResizeImage()

header
('Content-type: image/jpeg');

$image = new Imagick('image.jpg');
$image->adaptiveResizeImage(1024,768);

echo 
$image;
?>
