xfpoly

fill a polygon

Syntax

xfpoly(xv,yv,[fill])
h = xfpoly(...)

Arguments

xv,yv

two vectors of same size (the points of the polygon).

fill

integer, the color used to fill the polygon.

h

This optional output contains a handle to the created Polyline entity. For a list of properties, see polyline_properties.

Description

xfpoly fills a polygon with the current color or a color specified by the optional fill argument.

If fill is omitted, the polygon is filled with the current color and its contour is drawn with the current color and line style. If fill is present, it is used to fill the polygon as follows:

Examples

x=sin(2*%pi*(0:4)/5);
y=cos(2*%pi*(0:4)/5);
plot2d(0,0,-1,"010"," ",[-2,-2,2,2]);
gca().foreground = 5;
h = xfpoly(x,y);
h.fill_mode='off'; // shows only the contour

delete(h);

// Create a new polygon filled with color 3
// and its contour drawn with the current color
xfpoly(x,y,3);
