Java ISBN generator is a mature and reliable Java barcode generation component for creating ISBN barcodes in Java, Jasper Reports, iReport, and Eclipse BIRT projects. High-quality ISBN barcode images can be drawn and printed into GIF, BMP, PNG, JPEG/JPG & TIFF formats with Java ISBN barcode generator. Rich barcode options are provided to customize ISBN barcode properties in accordance with your needs.
ISBN information:
ISBN: is similar to EAN-13 in encoding scheme and is a 9-digit data length linear barcode type. It is commonly used for labeling books.
Available encoding data:
numeric digits: 0-9
12 digit data length only
The structure of an ISBN:
1. Fixed prefix:978 or 979
2. The company number(number system).
3. The item number( manufacture code).
4. The item reference(product code).
5. Check digit.

1. Generate ISBN in Java class with the changing of barcode properties.
// Create Java ISBN object
ISBN barcode = new ISBN();
// Set ISBN data text to encode
barcode.setData("978123456789");
// Generate ISBN barcode & print into Graphics2D object
//barcode.drawBarcode("Java Graphics2D object");
// Generate ISBN barcode & encode into GIF format
barcode.drawBarcode("C://barcode-isbn.gif");
// Generate ISBN barcode & encode into JPEG format
barcode.drawBarcode("C://barcode-isbn.jpg");
2. Generate & encode ISBN to EPS with changing the values concerned.
// Create Java ISBN object
ISBN barcode = new ISBN();
// Set ISBN data text to encode
barcode.setData("978000111222");
// Generate ISBN barcode & encode into EPS
barcode.drawBarcode2EPS("C://barcode-isbn.eps");
3. Generate & encode ISBN 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=978123456789&TYPE=isbn
3. Insert an image tag (img) into your page. For example,
<imgsrc="http://YourDomain:Port/barcode/barcode?DATA=978123456789&TYPE=isbn" />
4. Two ways to set the width and height of generated barcode ISBN image.
1. Set the values of the barcodeWidth and barcodeHeight properties.
or
2. Set X (bar module width) and Y (bar module height) values

/*
Use this method to generate barcode, and save into gif or jpeg files
1. to save into gif file, filename ends with ".gif", like "c:\\barcode.gif"
2. to save into jpeg file, filename ends with ".jpg", like "c:\\barcode.jpg"
*/
