Yes, I found the TVEllipse document and I had a look on that one.
The problem is that I want to make an array with this ellipse and they way I did it I only got a black window when I display it. My code is shown below

xc=90. ;center in x-direction
yc=50. ;center in y-direction

theta=45. ;angle to rotate
s=sin(theta*!pi/180.)
c=cos(theta*!pi/180.)
dx=xc
dy=yc

for x=0L, NX-1 do begin
for y=0L, NY-1 do begin
if ((xc + c*dx+s*dy )/2.)^2 + (( yc - s*dx+c*dy )/4.)^2 LT 100 then begin
Ellipse[x,y] = 10.
endif
endfor
endfor
tvscl, Ellipse
