Data Matrix Size Setting with C#, VB.NET Class in .NET WinForms

Install Data Matrix Barcode Creator Control into .NET Projects

  1. 1.
  2. 2.
    Add reference: Add "KeepAutomation.Barcode.Windows.dll" to your .NET project reference
  3. 3.
    Add to toolbox: To add BarcodeControl to your Visual Studio .NET toolbox
Copy the C# or VB.NET barcode sample procedure onto you projects to insert, produce a Data Matrix in .NET WinForms:
using KeepAutomation.Barcode.Bean;
BarCode barcode= new BarCode();
barcode.Symbology= KeepAutomation.Barcode.Symbology.DataMatrix;
barcode.CodeToEncode = "Data Matrix";
Dim barcode As KeepAutomation.Barcode.Bean.BarCode = New KeepAutomation.Barcode.Bean.BarCode

barcode.Symbology= KeepAutomation.Barcode.Symbology.DataMatrix
barcode.CodeToEncode = "Data Matrix"

Generating Data Matrix with Pixel as Unit of Measure

KA.Barcode Generator for .NET WinForms provides three units of measure for Data Matrix generation in .NET: pixel, inch and cm. Copy the C#/ VB.NET sample codings below to adjust:
barcode.BarcodeUnit = KeepAutomation.Barcode.BarcodeUnit.Pixel;
barcode.BarcodeUnit = KeepAutomation.Barcode.BarcodeUnit.Pixel

Drawing Data Matrix with Specified Format Mode

KA.Barcode Generator for .NET WinForms provides all 30 format modes as specified in ISO/IEC specification for Data Matrix (ECC200), including 24 square ones and 6 rectangular ones.Default is DataMatrixFormatMode.FM_12X12. You can select according to your inputting data capacity. Copy the sample code below to adjust it.
barcode.DataMatrixFormatMode = DataMatrixFormatMode.FM_10*10;
barcode.DataMatrixFormatMode = DataMatrixFormatMode.FM_10*10

Printing Data Matrix with Specific Bar Width & Height

If you want to produce a Data Matrix with specific module size, you can set Data Matrix bar width & bar height through "X" and "Y". Here is the C#/VB.NET sample code:
barcode.X = 3;
barcode.Y = 3;
barcode.X = 3
barcode.Y = 3

Creating Data Matrix with Fiexed Image Width & Height

In case some developers want to generate a Data Matrix to fit into a fixed space, they can resort to the BarCodeWidth & BarCodeHeight properties to adjust. Here is the demo code:
barcode.BarCodeHeight = 70;
barcode.BarCodeWidth = 175;
barcode.BarCodeHeight = 70
barcode.BarCodeWidth = 175

Printing Data Matrix with Quiet Zones / Margins on Four Sides

As is specified in the ISO/IEC 16022 specifications, a minimum X-wide quiet zone/ margin is required on four sides of a Data Matrix image for better readability and data security. Default value for the four margins is 0 pixel. You can adjust through the following samples:
barcode.TopMargin = 3;
barcode.BottomMargin = 3;
barcode.LeftMargin = 3;
barcode.RightMargin = 3;
barcode.TopMargin = 3
barcode.BottomMargin = 3
barcode.LeftMargin = 3
barcode.RightMargin = 3
Data Matrix Size Setting with Draw & Drop .NET WinForms Barcode Control
  1. 1.
    Add .NET WinForms barcode control to your Visual Studio toolbox
  2. 2.
    Drag and drop the BarCodeControl into the Forms and a Codabar image is generated
  3. 3.
    Right click the generated barcode image and select "Properties"
  4. 4.
    In the property panel, select "DataMatrix" in "Symbology" and write down encode data
  5. 5.
    Set "BarcodeUnit" to "Pixel", and "DataMatrixFormatMode" to "FM_10X10"
  6. 6.
    Set "X" to 3, "Y" to 3; Set "BarcodeWidth" to 200 and "BarcodeHeight" to 75
  7. 7.
    Set "TopMargin" & "BottomMargin" to 3; and set "RightMarign" & "LeftMargin" to 3
  8. 8.
    A Data Matrix barcodes with customized size will be updated in the form
