41    <div class="section">
42<p>Registers the baseline length to embed in the MP Attribute IFD.</p><p>This function is enabled if the <CODE><a href="../../../../nn/jpeg/CTR/JpegMpEncoder/StartMpEncoderFirst.html">StartMpEncoderFirst</a></CODE> or <CODE><a href="../../../../nn/jpeg/CTR/JpegMpEncoder/StartMpEncoderNext.html">StartMpEncoderNext</a></CODE> function is used as the encoding function. This is invalid when using <CODE><a href="../../../../nn/jpeg/CTR/JpegMpEncoder/StartMpEncoderLR.html">StartMpEncoderLR</a></CODE>. (The default value is registered.)</p><p>If you do not call this function, the library registers the default value (<CODE>0xFFFFFFFF/0xFFFFFFFF</CODE>). However, this value is not embedded unless the image's MP type is <CODE>MP_TYPE_CODE_MULTI_VIEW_DISPARITY_IMAGE</CODE> (a stereoscopic image).</p><p>Call this function before calling the encoding function. The values specified by this function are cleared after the encoding function completes, regardless of whether the encoding function succeeded or failed. When encoding multiple times, you must call this function before each encoding function call. The values specified by this function are also cleared if you specify <CODE>NULL</CODE> for the <SPAN class="argument">pValue</SPAN> argument, if you call the <a href="../../../../nn/jpeg/CTR/JpegMpEncoder/ClearMpBaselineLength.html"><CODE>ClearMpBaselineLength</CODE></a> function, or if you reinitialize the encoder object using the <a href="../../../../nn/jpeg/CTR/JpegMpEncoder/Initialize.html"><CODE>Initialize</CODE></a> function.</p><!-- write here --></div>
