}

}

g.setColor(logoConfig.getBorderColor());
}
//开始绘制图片
import java.util.Map;
for (int y = 0; y < h; y++)
{

public Color getBorderColor()

}
/**

}
}

for (int y = 0; y < h; y++)
* @param logoPic
import java.awt.BasicStroke;

image.setRGB(x, y, bm.get(x, y) ? 0xFF000000 : 0xFFCCDDEE);

}
}

* 将二维码生成为输出流

* 二维码的解析
}

return logoPart;
private final int logoPart;

* 
BinaryBitmap binaryBitmap = new BinaryBitmap(binarizer);
for (int x = 0; x < w; x++)

/**

import java.awt.image.BufferedImage;

/**
{

2.二维码的数据信息初始化

System.out.println("resultFormat = " + result.getBarcodeFormat());
import com.google.zxing.common.BitMatrix;
}

// 设置QR二维码的纠错级别（H为别）具体级别信息
throw new IllegalArgumentException("文件异常，或扩展名有问题！");
public int getBorder()
* 读取二维码图片，并构建绘图对象

import java.util.Date;
}
public BufferedImage getQR_CODEBufferedImage(String content, BarcodeFormat barcodeFormat, int width, int height, Map<EncodeHintType, ?> hints)
{

e.printStackTrace();

public int getLogoPart()
catch (WriterException e)
catch (Exception e)
{
int h = bm.getHeight();
// 用于设置QR二维码参数
* @param file
g.drawRoundRect(x, y, widthLogo, heightLogo, 15, 15);
* 
public void parseQR_CODEImage(File file)
BufferedImage image = fileToBufferedImage(bm);
}

{
}
return borderColor;
BufferedImage image = ImageIO.read(qrPic);
* @return
}
// 计算图片放置位置

ImageIO.write(image, imageFormat, os);
g.drawImage(logo, x, y, widthLogo, heightLogo, null);
catch (Exception e)

for (int x = 0; x < w; x++)
e.printStackTrace();
*            编码类型
import com.google.zxing.Result;

e.printStackTrace();
{
}
import java.awt.Color;

* @param bm
Map<EncodeHintType, Object> hints = new HashMap<EncodeHintType, Object>();
* 给二维码图片添加Logo

import com.google.zxing.EncodeHintType;
*/
{
}

{
LuminanceSource source = new BufferedImageLuminanceSource(image);

* 读取Logo图片
System.out.println("resultText = " + result.getText());
