Imagick::adaptiveResizeImage — Adaptively 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. This method is available if Imagick has been compiled against ImageMagick version 6.2.9 or newer.

Список параметров

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.
