CANVAS:fill_poly

    CANVAS:fill_poly(xytable, color)

Fill the content of a polygon through the points defined in the xytable with a specific color. The polygon must be a closed simple polygon.

Parameters

Parameter	Type	Description
xytable	#table	A Lua table {{x=x1,y=y1},{x=x2,y=y2}...}. Alternatively two tables of parameters containing an array of points may be provided, as in {x1,x2,..}, {y1,y2,..} similar to gre.poly_string().
color	#number	An RGB color value as an integer value.

Example

    -- Fill a triangle using a polygon
    function FillRedTrianglePoly(name)
        local canvas = gre.get_canvas(name)
        local size = canvas:get_dimensions()
        local mid = size.width / 2

        -- Shrink the bounds to make the lines visible
        size.height = size.height - 2
        size.width = size.width - 2

        local pts = {}
        table.insert(pts, {x=2,y=2})
        table.insert(pts, {x=mid,y=size.height})
        table.insert(pts, {x=size.width,y=2})
        table.insert(pts, pts[1])               --Close the polygon
        canvas:fill_poly(pts, 0xff0000)
    end
