## Methods

| Method | Description |
| --- | --- |
| [get_AspectRatio](./get_aspectratio/)() const | Height/Width ratio of 2D [BarCode](../../aspose.barcode/) module. |
| [get_EccType](./get_ecctype/)() const | Gets a Datamatrix ECC type. Default value: [DataMatrixEccType.Ecc200](../datamatrixecctype/). |
| [get_ECIEncoding](./get_eciencoding/)() const | Gets ECI encoding. Used when EncodeMode is Auto. Default value: ISO-8859-1 |
| [get_EncodeMode](./get_encodemode/)() const | Encode mode of Datamatrix barcode. Default value: [EncodeMode.Auto](../aztecencodemode/). |
| [get_IsReaderProgramming](./get_isreaderprogramming/)() const | Used to instruct the reader to interpret the data contained within the symbol as programming for reader initialization. Default value: false |
| [get_MacroCharacters](./get_macrocharacters/)() const | Macro Characters 05 and 06 values are used to obtain more compact encoding in special modes. Can be used only with [DataMatrixEccType.Ecc200](../datamatrixecctype/) or [DataMatrixEccType.EccAuto](../datamatrixecctype/). Cannot be used with [EncodeTypes.GS1DataMatrix](../encodetypes/gs1datamatrix/) Default value: [MacroCharacters.None](../barcodeclassifications/). |
| [get_StructuredAppendBarcodeId](./get_structuredappendbarcodeid/)() const | Barcode ID for Structured Append mode of Datamatrix barcode. Default value: 0 |
| [get_StructuredAppendBarcodesCount](./get_structuredappendbarcodescount/)() const | Barcodes count for Structured Append mode of Datamatrix barcode. Default value: 0 |
| [get_StructuredAppendFileId](./get_structuredappendfileid/)() const | File ID for Structured Append mode of Datamatrix barcode. Default value: 0 |
| [get_Version](./get_version/)() const | Gets a Datamatrix symbol size. Default value: [Version.Auto](../aztecencodemode/). |
| [set_AspectRatio](./set_aspectratio/)(float) | Height/Width ratio of 2D [BarCode](../../aspose.barcode/) module. |
| [set_EccType](./set_ecctype/)(DataMatrixEccType) | Sets a Datamatrix ECC type. Default value: [DataMatrixEccType.Ecc200](../datamatrixecctype/). |
| [set_ECIEncoding](./set_eciencoding/)(ECIEncodings) | Sets ECI encoding. Used when EncodeMode is Auto. Default value: ISO-8859-1 |
| [set_EncodeMode](./set_encodemode/)(DataMatrixEncodeMode) | Encode mode of Datamatrix barcode. Default value: [EncodeMode.Auto](../aztecencodemode/). |
| [set_IsReaderProgramming](./set_isreaderprogramming/)(bool) | Used to instruct the reader to interpret the data contained within the symbol as programming for reader initialization. Default value: false |
| [set_MacroCharacters](./set_macrocharacters/)(MacroCharacter) | Macro Characters 05 and 06 values are used to obtain more compact encoding in special modes. Can be used only with [DataMatrixEccType.Ecc200](../datamatrixecctype/) or [DataMatrixEccType.EccAuto](../datamatrixecctype/). Cannot be used with [EncodeTypes.GS1DataMatrix](../encodetypes/gs1datamatrix/) Default value: [MacroCharacters.None](../barcodeclassifications/). |
| [set_StructuredAppendBarcodeId](./set_structuredappendbarcodeid/)(int32_t) | Barcode ID for Structured Append mode of Datamatrix barcode. Default value: 0 |
| [set_StructuredAppendBarcodesCount](./set_structuredappendbarcodescount/)(int32_t) | Barcodes count for Structured Append mode of Datamatrix barcode. Default value: 0 |
| [set_StructuredAppendFileId](./set_structuredappendfileid/)(int32_t) | File ID for Structured Append mode of Datamatrix barcode. Default value: 0 |
| [set_Version](./set_version/)(DataMatrixVersion) | Sets a Datamatrix symbol size. Default value: [Version.Auto](../aztecencodemode/). |
| [ToString](./tostring/)() const override | Returns a human-readable string representation of this [DataMatrixParameters](./). |
