使用incam可以很轻松的增加2维码，这里通过另外一种方式玩转二维码的加法，
使用谷歌zxing.dll类库实现，将文字信息转为bitmap点阵后，在Genesis绘制点即可。
一.incam增加二维码效果
二.通过代码增加方PAD实现效果：
三.代码实现：
Genesis增加二维码代码
private void addQR()
{
CodeHelper qr = new CodeHelper();
Dictionary<EncodeHintType, object> hint = new Dictionary<EncodeHintType, object>();
hint.Add(EncodeHintType.CHARACTER_SET, "UTF-8");//设置内容编码
hint.Add(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.L);//错码率 L水平 7 % M水平 15 % Q水平 25 % H水平 30 %
hint.Add(EncodeHintType.QR_VERSION, );//大小 (V-1)*4 + 21（V是版本号）
hint.Add(EncodeHintType.MARGIN, );//边距
ZXing.Common.BitMatrix codeArray = qr.enMatrix("at00101ca0", , , BarcodeFormat.QR_CODE, hint); //at00101ca0为增加二维码内容
add add_ = new add();
gPP gp = new gPP();
gp.width = ;//PAD大小
gp.symbols = "s";//PAD形状为方PAD
for (int x = ; x < codeArray.Width; x++)
{
for (int y = ; y < codeArray.Height; y++)
{
if (codeArray[x, y])
{
gp.p.x = x * 0.5;
gp.p.y = y * 0.5;
add_.pad(gp); //增加方PAD PAD
}
}
}
}
zxing.dll重新封装后的二维码类
public class CodeHelper
{ public string CHARSET = "UTF-8"; public static int SaveTo(Bitmap bitmap, string filepath, string filename)
{
try
{
bitmap.Save(filepath + filename); return ;
}
catch (System.Exception ex)
{
return -;
