It is used primarily in labeling telecommunications equipment. The symbology is discrete and is able to encode the numbers 0 through 9, the dash symbol (-), and start/stop characters.
Code 11 is not terribly secure in that printing imperfections can quite easily convert one character into another valid character. Data integrity is obtained by using one, or sometimes two, check characters.
Sample of a Code 11 Barcode
2. Encoding Data Scope
Code 11 Barcode for Java supports:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
- (Dash)
3. How to Generate Barcode Image in Standalone Java Applications?
The following code illustrates how to create a barcode in a Java class
1 Linear linear = new Linear();
2 linear.setData("123456789");
3 linear.setType(Linear.CODE11);
4 linear.renderBarcode("c:/code11.gif");
Create a Linear object (line 1)
set Linear object properties (line 2 - 3)
save into gif file (line 4)
4. How to Generate Barcode Image in Web Applications?
There are two ways to create barcode images in your Java web applications.
This is the simplest way to stream barcode image using our provided barcode servlet classes.
And it will not save barcode images in your server side.
Under demo package, copy barcode folder to your java servlet container like tomcat.
To test your installation, goto http://YourDomain:Port/barcode/linear?Data=123456789&Type=CODE11
To create barcode image in your JSP or html page, you can pass the url to IMG tag src value.
For example, <img src="http://YourDomain:Port/barcode/linear?Data=123456789&Type=CODE11" />
The second method is similar with the way to generate barcode in Java applications.
Create a barcode image in server side
1 Linear linear = new Linear();
2 linear.setData("123456789");
3 linear.setType(Linear.CODE11);
4 linear.renderBarcode("C:/Tools/Tomcat 5.5/webapps/YourWebApp/bimages/barcode.gif");
In your JSP page, you can using IMG tag to display generated image, like <img src="http://YourDomain:Port/YourWebApp/bimages/barcode.gif" />
5. How to Generate Barcode Image in JasperReports?
The following jasper xml content illustrates how to insert a barcode into JasperReports
Just call Linear object method renderBarcode, e.g. linear.renderBarcode("c:/barcode.gif");
8. Barcode Property Settings
Set the type property to Linear.CODE11 Servlet Parameter: "Type".
Set the data property with the value to encode. Type is string.
Servlet Parameter: "Data".
Setting up barcode image size:
Set property uom (Unit of Measure) for properties barWidth, barHeight, leftMargin, rightMargin, topMargin and bottomMargin.
Default is Linear.UOM_PIXEL (0). Valid values are Linear.UOM_PIXEL (0), Linear.UOM_CM (1), Linear.UOM_Inch (2).
Servlet Parameter: "UOM".
Set the X (for barcode module width) and Y (for barcode module height) properties. Both types are float.
Servlet Parameter: "X", "Y".
Set the leftMargin, rightMargin, topMargin and bottomMargin properties, and types are all float.
Servlet Parameter: "LeftMargin", "RightMargin", "TopMargin", "BottomMargin".
Set the barcodeWidth (barcode image width) and barcodeHeight (barcode image height) properties. Both types are float.
Servlet Parameter: "BarcodeWidth", "BarcodeHeight".
Set the resolution property (Value is expressed in DPI - Dots per inch).
Servlet Parameter: "Resolution".
Setting up text style in barcode image:
Set the showText properties. If this value is true, barcode data will be displayed with the barcode.
Servlet Parameter: "ShowText".
Set the textFont property. The font used to display text in barcode image.
Servlet Parameter: "TextFont".
Set bearerBars property, if you want to draw borders around barcode image. Value can be Linear.BEARERBAR_UNSPECIFIED (-1. let library decide whether draw bear bars or not), Linear.BEARERBAR_NONE (0. no bear bars), Linear.BEARERBAR_FRAME (1. top, bottom, left, right borders drawn), Linear.BEARERBAR_TOPBOTTOM (2. only top, bottom's are drawn).
Servlet Parameter: "BearerBars".
Set rotate property, if you want to rotate barcode image.
Value can be 0 (Linear.ANGLE_0),
1 (Linear.ANGLE_90),
2 (Linear.ANGLE_180),
3 (Linear.ANGLE_270)
Servlet Parameter: "Rotate".
addCheckSum property is not applied here.
Barcode Library will automatically add one checksum character for data length from 1 to 9, otherwise two characters. Servlet Parameter: "AddCheckSum".
9. How to Set Generated Barcode Image Size?
To set barcode image width and height, there are two ways to do it.
1) You can set barcode image width and height through properties barcodeWidth and barcodeHeight values, barcode library will render the barcode image for you.
or
2) You can set X (barcode module width) and Y (barcode module height) values, barcode library will calculate the barcodeWidth and barcodeHeight values for you, and render the barcode image.
