MACROMEDIA FLASH 8-LEARNING ACTIONSCRIPT 2.0 IN FLASH Manual page 550

To create a hairline stroke:
1. Create a new Flash document and save it as hairline.fla.
2.
Add the following ActionScript to Frame 1 of your Timeline:
this.createEmptyMovieClip("drawing_mc", 10);
// create a red, hairline thickness line
drawing_mc.lineStyle(0, 0xFF0000, 100);
drawing_mc.moveTo(0, 0);
drawing_mc.lineTo(200, 0);
drawing_mc.lineTo(200, 100);
// create a blue line with a 1 pixel thickness
drawing_mc.lineStyle(1, 0x0000FF, 100);
drawing_mc.lineTo(0, 100);
drawing_mc.lineTo(0, 0);
drawing_mc._x = 100;
drawing_mc._y = 100;
The preceding code uses the Drawing API to draw two lines on the Stage. The first line is
red and has a thickness of 0, indicating a hairline thickness, the second line is blue and has
a thickness of 1 pixel.
3. Save the Flash document and select Control > Test Movie to test the SWF file.
Initially, both the red and blue lines look exactly the same. If you right-click in the SWF
file and select Zoom In from the context menu, the red line always appears as a 1-pixel
line; however, the blue line grows larger each time you zoom in to the SWF file.
