Icon	Name	Description / Applications
Path Basics
	AppendPointToPath	Appends a point to a path.
	ClosePath	Adds the segment connecting the last point with the first one in a path.
	CreateArcPath	Creates an open path containing cocircular, equidistant points.
	CreateCirclePath	Creates a closed path containing cocircular, equidistant points.
	CreateEllipsePath	Creates a closed path containing elliptical, equidistant points.
	CreateRectanglePath	Creates a closed path containing four vertices of rectangle.
	CreateSegmentPath	Creates an open path containing collinear, equidistant points.
	GetPathCharacteristicPoint	Returns the selected characteristic point of a path.
	GetPathCharacteristicPoint_Interpolated	Returns linear interpolation between two consecutive characteristic points of a path.
	GetPathSegment	Returns the selected segment of a path.
	GetPointOnPath	Returns a path point of desired distance (measured along path) from the first point of the path.
	OpenPath	Removes the segment connecting the last point with the first one in a path.
	RemovePointFromPath	Removes a point from a path.
	SetPathCharacteristicPoint	Modifies the value of a selected characteristic point.
	SkipEmptyPath	If the input path has at least one point, then it is copied to the output; otherwise Nil is returned. Secures against domain errors caused by empty paths, e.g. just before the PathBoundingBox filter is to be invoked.
	SkipNotPolygon	If the input path is closed and has no self-intersections, then it is copied to the output; otherwise Nil is returned.
	Subpath	Creates an open path from a continuous subsequence of the input path's points.
Path Combinators
Icon	Name	Description / Applications
	AveragePath	Computes the average of two paths (of equal size and type) point by point.
	ConcatenatePaths	Joins two open paths.
	ConcatenatePaths_OfArray	Joins open paths of an array.
	ConcatenatePaths_OfLoop	Joins open paths appearing in consecutive iterations.
Path Features
Icon	Name	Description / Applications
	PathArrayPoints	Converts an array of paths to an array of points.
	PathBoundingBox	Computes the smallest box containing a path.
	PathBoundingBox_OrNil	Computes the smallest box containing a path; returns NIL if the path is empty.
	PathDiameter	Finds the longest segment connecting two characteristic points of a path.
	PathEndpoints	Returns the two endpoints of a path.
	PathLength	Computes the total length of the input path.
	PathMassCenter	Computes the average of the path points (all, not only characteristic ones).
	PathMassCenter_OrNil	Computes the average of the path points (all, not only characteristic ones); returns NIL if the path is empty.
	PathSegments	Converts a path to an array of line segments.
	PathSize	Returns the number of characteristic points on the input path.
Path IO
Icon	Name	Description / Applications
	LoadPath	Loads serialized Path object from FIDATA file.
	SavePath	Saves serialized Path object as FIDATA file.
Path Spatial Transforms
Icon	Name	Description / Applications
	AlignPath	Moves a path from a local coordinate system to the absolute one. Required when there is a path defined in a local coordinate system, but the next image-related filter in the program does not have any inAlignment input.
	AlignPathArray	Moves an array of paths from a local coordinate system to the absolute one. Required when there are paths defined in a local coordinate system, but the next image-related filter in the program does not have any inAlignment input.
	RescalePath	Translates each point of a path proportionally to its distance to a reference point.
	RescalePathArray	Translates each point of each path proportionally to its distance to a reference point.
	ReversePath	Reverses the order of points in a path.
	RotatePath	Rotates a path clockwise around a center point.
	RotatePathArray	Rotates an array of paths clockwise around a center point.
	TranslatePath	Translates a path by a vector.
	TranslatePathArray	Translates an array of paths by a vector.
	TransposePath	Flips and rotates a path so that x-coordinates are exchanged with y-coordinates.
Polygon Relations
Icon	Name	Description / Applications
	TestPointInPolygon	Tests whether a point lies inside a polygon.
