Re: [Barcode4j-users] Barcode with some more text!

[Vu, A. T. <An...@vo...>]

Bravo, I want to find the solution, which exactly as you said. I've
tried as two files:
- The first file is only for main: GenerateJPEG.java
import org.krysalis.barcode4j.*;

public class GenerateJPEG 
{
   public static void main(String[] args)
  {
    generateSomeJPEG ai = new generateSomeJPEG();
  }
}
- The second file is the same program, which you send me as example:
generateSomeJPEG.java

import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.geom.AffineTransform;
import java.io.File;
import java.io.IOException;
import java.io.OutputStream;
import org.krysalis.barcode4j.tools.UnitConv;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.OutputStream;
import org.krysalis.barcode4j.impl.code128.Code128Bean;
import org.krysalis.barcode4j.tools.UnitConv;
import org.krysalis.barcode4j.*;
import org.krysalis.barcode4j.output.bitmap.BitmapBuilder;
import org.krysalis.barcode4j.output.java2d.Java2DCanvasProvider;


class generateSomeJPEG 
{
    public static void generateSomeJPEG() throws IOException 
    {
        Code128Bean bean = new Code128Bean();
        String msg = "12345";
        int orientation = 5;
        int resolution = 300;
        BarcodeDimension dim = bean.calcDimensions(msg);

        int bmw = UnitConv.mm2px(dim.getWidthPlusQuiet(orientation),
resolution);
        int bmh = UnitConv.mm2px(dim.getHeightPlusQuiet(orientation),
resolution);
        BufferedImage bi = new BufferedImage(bmw, bmh,
BufferedImage.TYPE_BYTE_BINARY);
        Graphics2D g2d = bi.createGraphics();
        g2d.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS, 
                             RenderingHints.VALUE_FRACTIONALMETRICS_ON);
        g2d.setBackground(Color.white);
        g2d.setColor(Color.black);
        g2d.clearRect(0, 0, bi.getWidth(), bi.getHeight());
        //Set up coordinate system: Barcode4J calculates in millimeters
internally
        g2d.scale(bi.getWidth() / dim.getWidthPlusQuiet(orientation), 
                  bi.getHeight() / dim.getHeightPlusQuiet(orientation));
        
        Java2DCanvasProvider canvas = new Java2DCanvasProvider(g2d,
orientation);
        bean.generateBarcode(canvas, msg);
        
        AffineTransform at = new AffineTransform();
        at.translate(5, 15);
        at.rotate(Math.PI / -4);
        g2d.transform(at);
        g2d.setFont(g2d.getFont().deriveFont(4.0f));
        g2d.drawString("Some text!", 10, 10);
        
        File outputFile = new File("C:\\out.jpg");
        OutputStream out = new java.io.FileOutputStream(outputFile);
        
        try 
        {
            BitmapBuilder.saveImage(bi, out, "image/jpeg", resolution);
        } 
        finally 
        {
            out.close();
        }
    }
}
This program has been run but I couldn't find the *.jpg in this folder
"C:\\out.jpg". Have you ever seen this problem?
Many thanks for your advanced.
Best regards,
Antoni
