== Arguments ==
:'''x1'''
::Horizontal offset from the left edge of the start of the line, in pixels.
:'''y1'''
::Vertical offset from the top edge of the start of the line, in pixels.
:'''x2'''
::Horizontal offset from the left edge of the end of the line, in pixels.
:'''y2'''
::Vertical offset from the top edge of the end of the line, in pixels.

== Description ==
Render an anti-aliased line to an ((OWNERDRAW)) control.

== Example ==
<code>
%fml

ctl[3]: OWNERDRAW(drawitem), Pos=(300,50), Size=(100, 100)

OnFilterStart: {

const int x = HDBUsToPixels(getCtlPos(n, 3));
  const int y = VDBUsToPixels(getCtlPos(n, 3));

// Start drawing on the OWNERDRAW
  startSetPixel(3);

// Fill the OWNERDRAW with black pixels
  setFill(RGB(0,0,0));

// Draw a diagonal red line
  setPenWidth(1);
  setLine(x, 0, 0, y, COLOR(RED));

// Draw a diagonal yellow antialiased line
  setThinLineAA(0, 0, x, y, COLOR(YELLOW));
