<div class="markdown level1 summary"><p>Constructs a new 'ForwCompTransfSpec' for the specified number of
components and tiles, the wavelet filters type and the parameter of the
option 'Mct'. This constructor is called by the encoder. It also checks
that the arguments belong to the recognized arguments list.</p>
<pre><code>       &lt;p&gt;This constructor chose the component transformation type depending
       on the wavelet filters : RCT with w5x3 filter and ICT with w9x7
       filter. Note: All filters must use the same data type.&lt;/p&gt;
