xfarc Fill a part of an ellipse

## Syntax

    xfarc(x,y,w,h,a1,a2)

## Arguments

x,y,w,h

  four real values defining a rectangle.

a1,a2

  real values defining a sector.

## Description

`xfarc` fills a part of an ellipse contained in the rectangle `(x,y,w,h)` (upper-left point, width, height), and in the sector defined by the angle `alpha1` and the angle `alpha1+alpha2`. `alpha1` and `alpha2` are given respectively by `a1/64` degrees and `a2/64` degrees. This function uses the current color and user coordinates.

If a2 is equal to 360*64, a complete circle will be drawn.

## Examples

    // isoview scaling
    plot2d(0,0,-1,"031"," ",[-2,-2,2,2])
    xfarc(-0.5,0.5,1,1,0,90*64)
    xfarc(0.5,0.5,1,1,0,360*64)
    gce().background = 2;

// isoview scaling plot2d(0,0,-1,"031"," ",[-2,-2,2,2]) xfarc(-0.5,0.5,1,1,0,90*64) xfarc(0.5,0.5,1,1,0,360*64) gce().background = 2;
