/** A method that circumvents the findMinAndMax when creating a float processor from an existing processor.  Ignores color calibrations and does no scaling at all. */

	final short[] pix = (short[])ip.getPixels();
	final float[] data = new float[pix.length];
	for (int i=0; i<pix.length; i++) data[i] = pix[i]&0xffff;
	final FloatProcessor fp = new FloatProcessorT2(ip.getWidth(), ip.getHeight(), data, ip.getColorModel(), ip.getMin(), ip.getMax());
	return fp;
