11 or 13 digits length only The structure of a Planet : 1. A long bar(frame bar)2. The encoded address information 3. Check digit 4. A feame bar Note that each code character is made up of 5 bars, either long or short. |

1. Generate Planet in Java class with the changing of barcode properties.
// Create Java Planet object
Planet barcode = new Planet();
// Set Planet data text to encode
barcode.setData("01234567891";);
// Generate Planet barcode & print into Graphics2D object
barcode.drawBarcode("Java Graphics2D object";);
// Generate Planet barcode & encode into GIF format
barcode.drawBarcode("C://barcode-planet.gif";);
// Generate Planet barcode & encode into JPEG format
barcode.drawBarcode("C://barcode-planet.jpg";);
2. Generate & encode Planet to EPS with changing the values concerned.
// Create Java Planet object
Planet barcode = new Planet();
// Set Planet data text to encode
barcode.setData("01234567891";);
// Generate Planet barcode & encode into EPS
barcode.drawBarcode2EPS("C://barcode-planet.eps";);
3. Generate & encode Planet 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=01234567891&TYPE=planet
3. Insert an image tag (img) into your page. For example,
<imgsrc="http://YourDomain:Port/barcode/barcode?DATA=0234567891&TYPE=planet" />
4. Two ways to set the width and height of generated Planet image.
1. Set the values of the barcodeWidth and barcodeHeight properties.
or
2. Set X (bar module width) and Y (bar module height) values
