question: private void drawBorder ( Graphics2D g , int width , int height , Color color , float size ) { int max = ( int ) ( Math . min ( ( height - 2 ) * size , height / 2.0f ) + 0.5 ) ; int alphaDelta = color . getAlpha ( ) / max ; for ( int i = 0 ; i < max ; i ++ ) { Shape s = shapeGenerator . createRoundRectangle ( i , i , width - 2 * i - 1 , height - 2 * i - 1 , CornerSize . CHECKBOX_INTERIOR ) ; Color newColor = new Color ( color . getRed ( ) , color . getGreen ( ) , color . getBlue ( ) , color . getAlpha ( ) - i * alphaDelta ) ; g . setPaint ( newColor ) ; g . draw ( s ) ; } }
