//为了可印刷名片、图册,可以去色

            //Logo            Image _logoImg = imgAgo;            _logoImg = ImageFix.Blocks((Bitmap)_logoImg);            _logoImg = ImageFix.ColorReplace((Bitmap)_logoImg, Color.Black, QrCodeEncoder.QRCodeForegroundColor);            g.DrawImage(_logoImg, (this.QrCodeW - this.QrCodeW / 4) / 2, (this.QrCodeH - this.QrCodeH / 4) / 2, this.QrCodeW / 4, this.QrCodeH / 4);//插入头像            return image;

 

//还可以自由配色

            //Logo            Image _logoImg = imgAgo;            _logoImg = ImageFix.Blocks((Bitmap)_logoImg);            _logoImg = ImageFix.ColorReplace((Bitmap)_logoImg, Color.Black, Color.Blue);            g.DrawImage(_logoImg, (this.QrCodeW - this.QrCodeW / 4) / 2, (this.QrCodeH - this.QrCodeH / 4) / 2, this.QrCodeW / 4, this.QrCodeH / 4);//插入头像
