The displacementMapFilter class gives us the ability to displace image pixels by using colors.   You can use this filter to achieve a warped or mottled effect on a BitmapData or MovieClip.  It uses the pixel values from the specified BitmapData (called the displacement map image) to perform a displacement. Combined with noise or perlinNoise effects this can be a powerfull image manipulation tool.

In this example I am using a gradient movieClip to displace my image and create a flag effect.  The black and white make my pixels grow or shrink using.

	DisplacementMapFilter(bitmap, point, componentX, componentY, scaleX, scaleY);

Where component X & Y describe which color channel to use in the map image to displace the x & y result. Use the slider to accentuate the componentX & Y values and reach the desired effect.
