Java Codabar Generator Implementation to Generate Codabar
1.Generate barcodes in Java class by changing of barcode properties.
// Create Java barcode object
Codbar barcode = new Codabar();
// Set barcode data text to encode
barcode.setData("1234567");
// Generate barcode & print into Graphics2D object
barcode.drawBarcode("Java Graphics2D object");
// Generate barcode & encode into GIF format
barcode.drawBarcode("C://barcode- codabar.gif");
// Generate barcode & encode into JPEG format
barcode.drawBarcode("C://barcode- codabar.jpg");
2. Generate & encode barcodes to EPS by changing the values concerned.
// Create Java Codabar object
Codabar barcode = new Codabar();
// Set Codabar data text to encode
barcode.setData("1234567");
// Generate Codabar barcode & encode into EPS
barcode.drawBarcode2EPS("C://barcode-codabar.eps");
3. Generate & encode barcodes in html or jsp pages.
1. Copy barcode folder and its contents from demo package to Apache Tomcat.
2. Start Apache Tomcat, go to http://YourDomain:Port/barcode/barcode?DATA=1234567&TYPE=CODABAR
3. Insert an image tag (img) into your page. For example,
<imgsrc="http://YourDomain:Port/barcode/barcode?DATA=1234567&TYPE=CODABAR" />
4. Two ways to set the width and height of generated barcode Codabar image:
1. Set the values of the barcodeWidth and barcodeHeight properties.
or
2. Set X (bar module width) and Y (bar module height) values
