Where does DataMatrixWriter live in the IronBarcode API?

DataMatrixWriter is a static class in the IronBarCode namespace, shipped in IronBarCode.dll. Call DataMatrixWriter.CreateDataMatrix directly to get a GeneratedBarcode, with no instance to construct.

How do you make a rectangular Data Matrix code in C#?

Call CreateDataMatrix with a DataMatrixWriter.DataMatrixShape and an explicit width and height. The simpler overload takes a single size instead and produces a square code.

Class DataMatrixWriter

A class allowing for advanced control on the generation of DataMatrix type barcodes.

DataMatrixWriter allows setting of the DataMatrix shape.

Generated Barcodes can be exported as Images, Bitmaps, Files, or Streams.

Syntax

public static class DataMatrixWriter : Object

Generating a Data Matrix code in C# runs through DataMatrixWriter, the dedicated writer for that 2D symbology. Its one static method returns a GeneratedBarcode, so there is nothing to construct: call DataMatrixWriter.CreateDataMatrix(...) and save, stamp, or export the result.

CreateDataMatrix is overloaded across input and shape. It encodes a string, byte[], or Stream, and each input has two forms. The simpler form takes a single size for a square code, while the second takes a DataMatrixWriter.DataMatrixShape along with an explicit width and height, which lets a developer request a rectangular Data Matrix where a layout calls for one. Data Matrix packs data densely into a small footprint, which suits marking small parts and components where a QR code would be too large. For QR codes or linear symbologies instead, use QRCodeWriter or BarcodeWriter. Because the call returns a GeneratedBarcode, the output format is chosen afterward, independent of how the value was encoded.

using IronBarCode;

DataMatrixWriter.CreateDataMatrix("SN-48291", 200).SaveAsPng("datamatrix.png");

The create 2D barcodes how-to generates a Data Matrix, and the create barcode images how-to covers the save formats.

Methods

CreateDataMatrix(Byte[], DataMatrixWriter.DataMatrixShape, Int32, Int32)

Renders a DataMatrix.

Overload methods and methods of the created GeneratedBarcode object allow for barcode sizes and colors to be customized.

Declaration

public static GeneratedBarcode CreateDataMatrix(byte[] binaryData, DataMatrixWriter.DataMatrixShape shape, int width = 500, int height = 500)

Parameters

Type	Name	Description
System.Byte[]	binaryData	The value of the DataMatrix as a byte array.
DataMatrixWriter.DataMatrixShape	shape	The shape of the DataMatrix.
System.Int32	width	The width of the DataMatrix in pixels.
System.Int32	height	The height of the DataMatrix in pixels.

Returns

Type	Description
GeneratedBarcode	A GeneratedBarcode object for the DataMatrix which can be manipulated, annotated, and saved to an IronDrawing object, an image file, a PDF, a MediaURL, or a data stream.

CreateDataMatrix(Byte[], Int32)

Renders a Square DataMatrix. For rendering of a rectangular DataMatrix, please find another overload of this method that supports width and height.

Overload methods and methods of the created GeneratedBarcode object allow for barcode sizes and colors to be customized.
