<p>
Encode metadata from the provided metadata to TIFF format.
<p>
The original binary image in the memory block <em>pData</em>, <em>size</em> is parsed and updated in-place if possible ("non-intrusive" writing). If that is not possible (e.g., if new tags were added), the entire TIFF structure is re-written to the <em>blob</em> ("intrusive" writing).<br>
The return value indicates which write method was used. If it is <code>wmNonIntrusive</code>, the original memory <em>pData</em>, <em>size</em> contains the result and <em>blob</em> is empty. If the return value is <code>wmIntrusive</code>, a new TIFF structure was created and returned in <em>blob</em>. The memory block <em>pData</em>, <em>size</em> may be partly updated in this case and should not be used anymore.<p>
<dl class="note" compact><dt><b>Note:</b></dt><dd>If there is no metadata to encode, i.e., all metadata containers are empty, then the return value is <code>wmIntrusive</code> and the <em>blob</em> is empty, i.e., no TIFF header is written.</dd></dl>
