79<h2>Description</h2>
80    <div class="section">
81<p>Adds a command for clearing <SPAN class="Argument"><CODE>Texture2DResource</CODE></SPAN> using the specified value to the current command list.</p><p>If the pixel format of the <CODE>Texture2DResource</CODE> to be cleared is smaller than 32 bits, 32-bit data is created for the specified value by repeating the number of times given by the resource pixel format size. FCRAM memory cannot be cleared.  A function with the same functionality as <CODE>nngxAddMemoryFillCommand</CODE> is called internally. This function adds commands to the command list. Refer to the Programming Manual for details.</p><!-- write here --></div>
