Defined by an array on N points in a 2-D space.

One can draw the contour of the polyline or/and its fill area. Example:

{
   Double_t x[5] = {.2,.7,.6,.25,.2};
   Double_t y[5] = {.5,.1,.9,.7,.5};
   TPolyLine *pline = new TPolyLine(5,x,y);
   pline->SetFillColor(38);
   pline->SetLineColor(2);
   pline->SetLineWidth(4);
   pline->Draw("f");
   pline->Draw();
}

◆ DistancetoPrimitive()

Int_t TPolyLine::DistancetoPrimitive	(	Int_t	px,
		Int_t	py
	)

overridevirtual

Returns closest distance in pixels from point (px, py) to a polyline.

First looks for distances to the points of the polyline. Stops search and returns if a vertex of the polyline is found to be closer than 10 pixels. Thus the return value may depend on the ordering of points in the polyline.

Then looks for distances to the lines of the polyline. There is no arbitrary cutoff; any distance may be found.

Finally checks whether (px, py) is inside a closed and filled polyline. (Must be EXACTLY closed. "Filled" means fill color and fill style are both non-zero.) If so, returns zero.

Returns 9999 if the polyline has no points.
