      Modifier and Type Method Description
      static java.awt.Shape getShape​(java.awt.Image image)
      Given an image, possibly with a transparent background, return the Shape of the opaque part of the image
      static java.awt.Shape getShape​(java.awt.image.BufferedImage image, int max)
      Given an image, possibly with a transparent background, return the Shape of the opaque part of the image If the image is larger than max in either direction, scale the image down to max-by-max, do the trace (on fewer points) then scale the resulting shape back up to the size of the original image.
