Imagick::distortImage — Distorts an image using various distortion methods
Descrição
Esta função é EXPERIMENTAL. Isso quer dizer que o comportamento desta função e seu nome, incluindo TUDO o que está documentado aqui pode mudar em futuras versões do PHP, SEM QUALQUER NOTIFICAÇÃO. Esteja avisado, e use esta função por sua própria conta e risco.
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.
