[flexcoders] Print Inverted Image?

[pliechty]

I am trying to print an image with a filter on it.  The filter inverts the 
colors of the image.  I add the imgBox to the printJob.  But, the image doesn't 
print with the filter applied.  Here is the code:

  <mx:Script>
      <![CDATA[
    private function invert():void
    {
      var matrix:Array = new Array();
      matrix = matrix.concat([-1,  0,  0, 0, 255]);
      matrix = matrix.concat([ 0, -1,  0, 0, 255]);
      matrix = matrix.concat([ 0,  0, -1, 0, 255]);
      matrix = matrix.concat([ 0,  0,  0, 1,   0]);
      imgBox.filters = [new ColorMatrixFilter(matrix)];
    }
       ]]>
   </mx:Script>

  <mx:VBox id="imgBox" width="100%" height="100%" borderColor="red" 
borderStyle="solid" borderThickness="2">
    <common:SmoothImage id="sourceImg" complete="previewPage()" 
horizontalAlign="center"/>
  </mx:VBox>
