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, 11);//大小 (V-1)*4 + 21（V是版本号） hint.Add(EncodeHintType.MARGIN, 0);//边距 ZXing.Common.BitMatrix codeArray = qr.enMatrix("at00101ca0", 61, 61, BarcodeFormat.QR_CODE, hint); //at00101ca0为增加二维码内容 add add_ = new add(); gPP gp = new gPP(); gp.width = 500;//PAD大小 gp.symbols = "s";//PAD形状为方PAD for (int x = 0; x < codeArray.Width; x++) { for (int y = 0; 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
