QRCode2

中文 | English

This library is used to generate a variety of common QRCode.

Guide package

Copy qrcode 2.1.0.jar and zxing3.2.1.jar to the project, Build Pah can be used.

Use

public class EncodeMain {
	private static String contents = "作者:Luzhuo   博客:http://blog.csdn.net/Rozol   Github:https://github.com/lzluzhuo"; // qrcode content 
	private static int width = 340; // qrcode width
	private static int height = 340; // qrcode height
	private static File savefile = new File("C:\\我的电脑\\" + File.separator + System.currentTimeMillis() + ".png"); // file save path
	private static File basemapfile =  new File("C:\\我的电脑\\logo2.jpg"); // base map
	private static File logofile = new File("C:\\我的电脑\\logo.jpg"); // logo
	
	public static void main(String[] args) throws WriterException, IOException {
		// Calculate the size of the base map, according to the size of the base map to calculate the size of two-dimensional code, there is no such demand is not necessary
		int[] size = QRUtils.getImageFilePxSize(basemapfile);
		if(size == null) return;
		width = size[0]; height = size[1];
		
    	// 1. Create a QRCode source data set.
    	QRCode qrcode = new QRCode().createQRCode(contents);
    	
    	// 2. The style class handles the QRCode source data set.
    	// QRStyle qrstyle = new QRStyle(qrcode, QRStyles.Default);
    	// QRStyle qrstyle = new QRStyle(qrcode, QRStyles.OnlyBlack);
    	// QRStyle qrstyle = new QRStyle(qrcode, QRStyles.DefaultTranslucent);
    	// QRStyle qrstyle = new QRStyle(qrcode, QRStyles.DefaultTranslucentBorder);
    	QRStyle qrstyle = new QRStyle(qrcode, QRStyles.DefaultPoint);
    	
    	// 3. QRCode generates a graphic data array.
    	QRMatrix qrMatrix = new QRMatrix().createMatrix(qrcode, width, height, qrstyle);
    	
    	// 4. The pattern data array is patterned.
    	// QRGraphical qrGraphical = new QRGraphical().decode(qrMatrix);
    	QRGraphical qrGraphical = new QRGraphical().decode(qrMatrix, basemapfile);
    	
    	// 5. Writes the generated graph to a file.
    	new QRWriteToFile().writeToFile(qrGraphical, savefile);
    	// new QRWriteToFile().writeToFile(qrGraphical, savefile, logofile);
	}

}

Style

  • 1:QRStyles.Default

     Reference code:
 QRCode qrcode = new QRCode().createQRCode(contents);
 QRStyle qrstyle = new QRStyle(qrcode, QRStyles.Default);
 QRMatrix qrMatrix = new QRMatrix().createMatrix(qrcode, width, height, qrstyle);
 QRGraphical qrGraphical = new QRGraphical().decode(qrMatrix);
 new QRWriteToFile().writeToFile(qrGraphical, savefile);

  • 2:QRStyles.Default + logo

     Reference code:
 QRCode qrcode = new QRCode().createQRCode(contents);
 QRStyle qrstyle = new QRStyle(qrcode, QRStyles.Default);
 QRMatrix qrMatrix = new QRMatrix().createMatrix(qrcode, width, height, qrstyle);
 QRGraphical qrGraphical = new QRGraphical().decode(qrMatrix);
 new QRWriteToFile().writeToFile(qrGraphical, savefile, logofile);

  • 3:QRStyles.OnlyBlack

     Reference code:
 QRCode qrcode = new QRCode().createQRCode(contents);
 QRStyle qrstyle = new QRStyle(qrcode, QRStyles.OnlyBlack);
 QRMatrix qrMatrix = new QRMatrix().createMatrix(qrcode, width, height, qrstyle);
 QRGraphical qrGraphical = new QRGraphical().decode(qrMatrix, basemapfile);
 new QRWriteToFile().writeToFile(qrGraphical, savefile);

  • 4:QRStyles.DefaultTranslucent

     Reference code:
 QRCode qrcode = new QRCode().createQRCode(contents);
 QRStyle qrstyle = new QRStyle(qrcode, QRStyles.DefaultTranslucent);
 QRMatrix qrMatrix = new QRMatrix().createMatrix(qrcode, width, height, qrstyle);
 QRGraphical qrGraphical = new QRGraphical().decode(qrMatrix, basemapfile);
 new QRWriteToFile().writeToFile(qrGraphical, savefile);

  • 5:QRStyles.DefaultTranslucentBorder

     Reference code:
 QRCode qrcode = new QRCode().createQRCode(contents);
 QRStyle qrstyle = new QRStyle(qrcode, QRStyles.DefaultTranslucentBorder);
 QRMatrix qrMatrix = new QRMatrix().createMatrix(qrcode, width, height, qrstyle);
 QRGraphical qrGraphical = new QRGraphical().decode(qrMatrix, basemapfile);
 new QRWriteToFile().writeToFile(qrGraphical, savefile);

  • 6:QRStyles.DefaultPoint

     Reference code:
 QRCode qrcode = new QRCode().createQRCode(contents);
 QRStyle qrstyle = new QRStyle(qrcode, QRStyles.DefaultPoint);
 QRMatrix qrMatrix = new QRMatrix().createMatrix(qrcode, width, height, qrstyle);
 QRGraphical qrGraphical = new QRGraphical().decode(qrMatrix, basemapfile);
 new QRWriteToFile().writeToFile(qrGraphical, savefile);

Other

You can use the generated two-dimensional code to use some filter algorithms, or use PS to produce beautiful two-dimensional code (the library is mainly used to generate rather than landscaping):
