    Imagick::extentImage — Set image size

    Descrizione

    public Imagick::extentImage(
        int $width,
        int $height,
        int $x,
        int $y
    ): bool

    Comfortability method for setting image size. The method sets the image size and allows setting x,y coordinates where the new area begins. Questo metodo è disponibile se Imagick è stato compilato con ImageMagick versione 6.3.1 o successive.

    Attenzione

    Prior to ImageMagick 6.5.7-8 (1623), $x was positive when shifting to the left and negative when shifting to the right, and $y was positive when shifting an image up and negative when shifting an image down. Somewhere betwen ImageMagick 6.3.7 (1591) and ImageMagick 6.5.7-8 (1623), the axes of $x and $y were flipped, so that $x was negative when shifting to the left and positive when shifting to the right, and $y was negative when shifting an image up and positive when shifting an image down. Somewhere between ImageMagick 6.5.7-8 (1623) and ImageMagick 6.6.9-7 (1641), the axes of $x and $y were flipped back to pre-ImageMagick 6.5.7-8 (1623) functionality.
