Imagick::adaptiveResizeImageAdaptively resize image with data dependent triangulation


bool Imagick::adaptiveResizeImage ( int $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. Цей метод доступний якщо Imagick був зібраний з версією ImageMagick 6.2.9 або новішою.

Зауваження: The behavior of the parameter bestfit changed 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. If bestfit parameter is used both width and height must be given.



The number of columns in the scaled image.


The number of rows in the scaled image.


Whether to fit the image inside a bounding box.

Приклад #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.

('Content-type: image/jpeg');

$image = new Imagick('image.jpg');
