| Leadtools.Barcode Namespace : DatamatrixBarcodeReadOptions Class |
[TypeConverterAttribute()] [SerializableAttribute()] public class DatamatrixBarcodeReadOptions : BarcodeReadOptions, System.ICloneable
'Declaration
<TypeConverterAttribute()> <SerializableAttribute()> Public Class DatamatrixBarcodeReadOptions Inherits BarcodeReadOptions Implements System.ICloneable
'Usage
Dim instance As DatamatrixBarcodeReadOptions
public sealed class DatamatrixBarcodeReadOptions : System.ICloneable
@interface LTDatamatrixBarcodeReadOptions : LTBarcodeReadOptions
public class DatamatrixBarcodeReadOptions extends BarcodeReadOptions
function Leadtools.Barcode.DatamatrixBarcodeReadOptions()
[TypeConverterAttribute()] [SerializableAttribute()] public ref class DatamatrixBarcodeReadOptions : public BarcodeReadOptions, System.ICloneable
The DatamatrixBarcodeReadOptions class is used to control the options when reading Datamatrix barcodes using LEADTOOLS. Set the options in two ways:
The BarcodeReader class contains default options for each barcode symbology (or group of common symbologies). These options can be retrieved using the BarcodeReader.GetDefaultOptions method passing BarcodeSymbology.Datamatrix. Then change the members of the returned DatamatrixBarcodeReadOptions by casting it from BarcodeReadOptions to DatamatrixBarcodeReadOptions.
It is also possible to create an instance of the DatamatrixBarcodeReadOptions class and use it directly in BarcodeReader.ReadBarcode and BarcodeReader.ReadBarcodes methods that accept a single or array of options as an input parameter.
The base BarcodeReadOptions contains the following members and features:
| Member | Description |
|---|---|
| BarcodeReadOptions.ForeColor |
Controls the barcode foreground color (color of the bars or symbols) to use when reading a barcode from a colored image. |
| BarcodeReadOptions.BackColor |
Controls the barcode background color (color of the spaces) to use when reading a barcode from a colored image. |
| BarcodeReadOptions.Load and BarcodeReadOptions.Save |
Can be used to save or load the options to/from an XML file or stream. |
| BarcodeReadOptions.GetSupportedSymbologies |
This class overrides the base class method to return an array containing the following symbologies: BarcodeSymbology.Datamatrix |
In addition to these features and members, DatamatrixBarcodeReadOptions contains these Datamatrix barcodes specific features:
| Member | Description |
|---|---|
| EnableDoublePass |
Enable internal auto preprocessing of the image data if no Datamatrix barcode was found |
| EnableDoublePassIfSuccess |
Enable internal auto preprocessing of the image data even if some Datamatrix barcodes were found |
| EnableInvertedSymbols |
Forces the Datamatrix reader to search for both inverted and normal (non-inverted) symbols |
| EnableFastMode |
Fast barcode reading (recommended). It is suitable for most barcode qualities either good or poor |
| ReadSquareSymbolsOnly |
Enable reading square symbols only. Otherwise, read rectangular and square symbols |
| EnableSmallSymbols |
Enables reading small symbols that are 20 to 40 pixels |
| GS1toHRI |
