public void setParam(ImageDecodeParam param) {
        this.param = param;
    }
Sets the current parameters to an instance of the
<code>ImageDecodeParam</code> interface.  Concrete
implementations of <code>ImageDecoder</code> may throw a
<code>RuntimeException</code> if the <code>param</code>
argument is not an instance of the appropriate subclass or
subinterface.  For example, a <code>JPEGImageDecoder</code>
will expect <code>param</code> to be an instance of
<code>JPEGDecodeParam</code>.
