34<P>
35Returns the maximum value that can be specified for <SPAN class="argument">lines</SPAN> in the <code><A href="CAMERA_SetTransferLines.html">CAMERA_SetTransferLines</A></code> function to avoid fractions at the end of a frame.

38<H2>Description</H2>
39<P>
40As described in <code><A href="CAMERA_SetTransferLines.html">CAMERA_SetTransferLines()</A></code>, if the line count and the height specified by a <code><A href="CAMERA_I2CSize.html">CAMERA_I2CSize*</A></code> function or the <code><A href="CAMERA_SetTrimmingParams.html">CAMERA_SetTrimmingParams</A></code> function are not divisible, a new DMA will be started synchronously with the start of a camera V-Blank and the odd amount remaining at the end of the frame will be transferred. In this case, the new DMA will be left running in the camera V-Blank. In order to avoid this, it is possible to find the maximum line count that will keep odd amounts from occurring.
