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;
