    imagecopymerge — Copy and merge part of an image

    Beschreibung

    imagecopymerge(
        GdImage$dst_image,
        GdImage$src_image,
        int$dst_x,
        int$dst_y,
        int$src_x,
        int$src_y,
        int$src_width,
        int$src_height,
        int$pct
    ): bool

    Copy a part of src_image onto dst_image starting at the x,y coordinates src_x, src_y with a width of src_width and a height of src_height. The portion defined will be copied onto the x,y coordinates, dst_x and dst_y.

    Parameter-Liste

    dst_image

    Ressource des Zielbildes.

    src_image

    Ressource des Quellbildes.

    dst_x

    x-coordinate of destination point.

    dst_y

    y-coordinate of destination point.

    src_x

    x-coordinate of source point.

    src_y

    y-coordinate of source point.

    src_width

    Breite der Quelle.

    src_height

    Höhe der Quelle.

    pct

    The two images will be merged according to pct which can range from 0 to 100. When pct = 0, no action is taken, when 100 this function behaves identically to imagecopy() for pallete images, except for ignoring alpha components, while it implements alpha transparency for true colour images.

    Rückgabewerte

    Gibt bei Erfolg true zurück. Bei einem Fehler wird false zurückgegeben.
