Method getFloatPolygon

ij/src/main/java/ij/gui/ShapeRoi.java:1121–1123

Returns a FloatPolygon with all vertices of the flattened shape, i.e., the shape approximated by straight line segments. This method is for listing the coordinates and creating the convex hull. @param flatness Roughly the maximum allowable distance between the shape and the approximate polygon @p

(double flatness, boolean separateSubpaths, boolean addPointForClose, boolean absoluteCoord)

	 *   Note that with <code>addPointForClose = false</code>, there is no distinction between open and closed subpaths.
	 *  @param absoluteCoord specifies whether the coordinates should be with respect to image bounds, not Roi bounds. */
