= setThinEllipseAA =

== Syntax ==
{{bool setThinEllipseAA (int left, int top, int right, int bottom, int color)}}

== Arguments ==
:'''left'''
::Left-most bound of the ellipse, in pixels.
:'''top'''
::Top-most bound of the ellipse, in pixels.
:'''right'''
::Right-most bound of the ellipse, in pixels.
:'''bottom'''
::Bottom-most bound of the ellipse, in pixels.
:'''color'''
::Color value for the ellipse.

== Returns ==
True if the function succeeded, false otherwise

== Description ==
Render an anti-aliased ellipse or circle to an ((OWNERDRAW)) control.

== Example ==
<code>
%fml

ctl(1): OWNERDRAW(drawitem), Pos=(300,50), Size=(100, 100)

OnFilterStart: {

// Maximum X/Y pixel co-ords of ownerdraw
  int maxxpixel = HDBUsToPixels(100)-1;
  int maxYpixel = VDBUsToPixels(100)-1;

// Start using setPixel drawing on OWNERDRAW control 1
  startSetPixel(1);

// Draw rectangle around OWNERDRAW area
  setRectFrame(0, 0, maxxpixel, maxYpixel, RGB(0,0,0));

// Draw an outline of a red ellipse
  setThinEllipseAA(5, 5, 200, 150, RGB(255, 0, 0));

// Draw an outline of a blue circle
  setThinEllipseAA(25, 50, 150, 175, RGB(0, 0, 255));

// Stop using setPixel drawing
  endSetPixel(1);

return true;
}
