45<P>
46Specifies the positions to use for trimming. Trimming includes the pixel with an x-coordinateof (<SPAN class="argument">srcHeight</SPAN>-<SPAN class="argument">destHeight</SPAN>)/2 and a y-coordinate of (<SPAN class="argument">srcWidth</SPAN>-<SPAN class="argument">destWidth</SPAN>)/2, but not the pixel with an x-coordinate of (<SPAN class="argument">srcHeight</SPAN>+<SPAN class="argument">destHeight</SPAN>)/2 and a y-coordinate of <SPAN class="argument">srcWidth</SPAN>+<SPAN class="argument">destWidth</SPAN>)/2. The camera resolution width and height specified as arguments should be the same as the size specified to the <code><A href="CAMERA_I2CSize.html">CAMERA_I2CSize*</A></code> functions. <BR><BR>To use this function, trimming must first be enabled by the <code><A href="CAMERA_SetTrimming.html">CAMERA_SetTrimming</A></code> function. <BR><BR>The width (<SPAN class="argument">destWidth</SPAN>) of the trimming range specified in this function must be an even number.<BR><BR>The following behavior will result if the trimming range is not specified properly with this function.
47<ul>
48<li>This function will do nothing and return when the trimming range exceeds the camera resolution size (<SPAN class="argument">destWidth</SPAN> &gt; <SPAN class="argument">srcWidth</SPAN> or <SPAN class="argument">destHeight</SPAN> &gt; <SPAN class="argument">srcHeight</SPAN>).</li>
