It is also known as ANSI/AIM
Code 93, ANSI/AIM Code 93, Uniform Symbology Specification Code 93, USS Code
93, USS 93, Code 9/3, USS-93, USD-3, Code 93 Extended, and Code 93 Full ASCII
Code 93 is a barcode symbology designed in 1982 by Intermec to provide a higher density and data security enhancement to Code 39. It is an alphanumeric, variable length symbology. Code 93 is used primarily by Canadian postal office to encode supplementary delivery information. Every symbol includes two check characters.
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=CODE93
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=CODE93" />
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.CODE93);
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" />
Set the type property to Linear.CODE93 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. Check character "C" and "K" will always be applied.
Servlet Parameter: "AddCheckSum".
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.
