Descrição

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

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.
