.SH NAME
xarc - draws a part of an ellipsis
.SH CALLING SEQUENCE
.nf
xarc(x,y,w,h,a1,a2)
.fi
.SH PARAMETERS
.TP 15
x,y,w,h
: real (rectangle def)
.TP 15
a1,a2
: real (angle def)
.SH DESCRIPTION
Draws a portion of an ellipsis contained in the rectangle \fV(x,y,w,h)\fR
( Upper-Left point, Width, Height), and in the sector delimited by
the angle \fValpha1\fR and the angle \fValpha1+alpha2\fR. \fValpha1\fR and \fValpha2\fR are
given respectively by \fVa1/64\fR degrees and \fVa2/64\fR degrees.
This function uses the current graphic state and graphic scale.
which can be set by calling a high level drawing function such as \fVplot2d\fR.
.SH EXAMPLE
.nf
// isoview scaling
plot2d(0,0,-1,"031"," ",[-2,-2,2,2])
xset("dashes",3);
xarc(-1,1,2,2,0,90*64)
