Imagick::distortImage — Distorts an image using various distortion methods
Beschreibung
Diese Funktion ist EXPERIMENTELL. Das Verhalten, der Funktionsname und alles Andere was hier dokumentiert ist, kann sich in zukünftigen PHP-Versionen ohne Ankündigung ändern. Seien Sie gewarnt und verwenden Sie diese Funktion auf eigenes Risiko.
Distorts an image using various distortion methods, by mapping color lookups of the source image to a new destination image usally of the same size as the source image, unless 'bestfit' is set to true. If 'bestfit' is enabled, and distortion allows it, the destination image is adjusted to ensure the whole source 'image' will just fit within the final destination image, which will be sized and offset accordingly. Also in many cases the virtual offset of the source image will be taken into account in the mapping. This functionality is present if Imagick is compiled against ImageMagick 6.3.6 or later.
