13.如何进行双面扫描？
function DuplexScan_Click(){
DWObject.SelectSource();
DWObject.OpenSource();
DWObject.IfShowUI = false;
DWObject.IfDuplexEnabled = true; //enable duplex
DWObject.AcquireImage();
} 
此次更新和改进仅适用于Windows Edition。
用于1D条形码的新de-blur算法，可以提高在模糊图像中扫描线性条形码时的精度。
新的多线程处理可以提高1D条形码的扫描精度。
添加了新的API，你可以指定页码、条形码区域、条形码宽度、条形码高度、条形码模块大小和条形码角度来进行条形码检测。这大大提高了解码工作和条形码读取的效率。
