Transparency issues..

[arieltal]

hello, i'm trying to eliminate the background of a sprite, i have found several forum talks about it, the problem is that
i manage to set the alpha of the color i want to make transparent to zero, but when i draw the image, it has a gray background instead of what color it used to be. please help.
code:

public void cleanImage(BufferedImage target,int r,int g,int b,int a)
  {
	  int col = ((a << 24) | (r << 16) | (g << 8) | b);
	  int trans = ((0 << 24) | (r << 16) | (g << 8) | b);
	  int [] pixels = ((DataBufferInt)target.getRaster().getDataBuffer()).getData();
	  ColorModel cm = target.getColorModel();
	  SampleModel sm = target.getRaster().getSampleModel();
	  for (int i = 0;i<pixels.length;i++)
			if (pixels[i] == col) pixels[i] = trans;//-1118482;
	  DataBuffer db = new DataBufferInt(pixels,target.getHeight()*target.getWidth());
		WritableRaster wr = Raster.createWritableRaster(sm,db,null);
		target = new BufferedImage(cm, wr, false, null);
  }

Are you using an image filter as noted in this post on stackoverflow.com?

not in that perticular procedure, but i have copy-pasted that code and it did not work.. :(
