Class Method Details

.intensify(original_img) ⇒ Magick::ImageList

Takes in an image, composites a smaller version of it, then returns an animated intensified image image. Best when used with Turboize.turbo to generate multiple intense speeds.

Parameters:

  • original_img (Array) —

    An array of [Magick::ImageList]s

Returns:

  • (Magick::ImageList) —

    The intensified image

.intensify_from_file(path) ⇒ Magick::ImageList

Takes in an image from a file, composites a smaller version of it, then returns an animated intensified image image. Best when used with Turboize.turbo to generate multiple intense speeds. Wrapper around Teaas::Intensifty.intensify

Parameters:

  • path (String) —

    Path to the image to be created to an intensified image

Returns:

  • (Magick::ImageList) —

    The intensified image
