Barcode Data Matrix Introduction

Java Data Matrix Generator - Valid Data Scope

• All 128 characters of ASCII
• Values 128-255 in accordance with ISO 8859-1. These are referred to as extended ASCII.

How to Generate Data Matrix in Java Class?

Top

// Create Java Data Matrix object 
DataMatrix barcode = new DataMatrix(); 

// Set Data Matrix data text to encode
barcode.setData("DataMatrix-IN-JAVA"); 

// Generate Data Matrix barcode & print into Graphics2D object
barcode.drawBarcode("Java Graphics2D object"); 

// Generate Data Matrix barcode & encode into GIF format
barcode.drawBarcode("C://barcode-datamatrix.gif"); 

// Generate Data Matrix barcode & encode into JPEG format
barcode.drawBarcode("C://barcode-datamatrix.jpg"); 

// Generate Data Matrix barcode & encode into EPS
barcode.drawBarcode2EPS("C://barcode-datamatrix.eps"); 

How to Create Data Matrix image in HTML or JSP pages?

Top

1. Under demo package, copy barcode folder and its contents to your tomcat.
2. Start tomcat, navigate to http://YourDomain:Port/barcode/barcode?DATA=DataMatrixEncodingData&TYPE=datamatrix
3. To create bar code images in html or jsp pages, you can insert a image tag (img) into your page.
4. For example, <img src="http://YourDomain:Port/barcode/barcode?DATA=DataMatrixEncodingData&TYPE=datamatrix"/>

            response.setDateHeader("Expires", 0); 
           
            // Generate DataMatrix barcode & output to ServletOutputStream
            barcode.drawBarcode(servletoutputstream); 
      
        } catch (Exception e) { 
            throw new ServletException(e); 
        } 
    }

How to Generate GS1 Compatible Data Matrix?

Top

1. You need set property fnc1Mode value to IBarcode.FNC1_ENABLE (1), to indicate that the generated data matrix is GS1 compatible.
2. You can use 2 methods to input GS1 AI elements
• Parenthesis: to use parenthesis to indicate an AI code. Eg. (01)12345
• Escape Tilde: to use ~ai* to indicate an AI while * is digit number of the AI (from 2 ~ 7). Eg. ~ai20112345 same as (01)12345
• Note 1: To use escape tilde, you need set processTilde property to true.
• Note 2: You can not use parenthesis character in the data message, except, user enables ProcessTilde flag and use ~040 and ~041 to replace '(' and ')' Parenthesis must in pair, otherwise, the output would be incorrect.

Data Matrix Reader Programming and Macro 05, Macro 06

Top

1. ~rp: Reader Programming (for ASCII mode and Auto mode only)
This should be located at the beginning of the encoding data, e.g. data = "~rpABCD1234".
2. ~m5: 05 Macro (for ASCII mode and Auto mode only)
This should be located at the beginning of the encoding data, e.g. data = "~m5ABCD1234".
3. ~m6: 06 Macro (for ASCII mode and Auto mode only)
This should be located at the beginning of the encoding data, e.g. data = "~m6ABCD1234".

How to Set Generated Barcode Data Matrix Image Width and Height?

Top

1. You can set barcode image width and height through properties barcodeWidth and barcodeHeight values.
2. Or you can set X (bar module width) and Y (bar module height) values
