Class QrReader

Provides functionality to read QR codes with optional settings.

Inheritance

System.Object

QrReader

Namespace: IronQr

Assembly: IronQr.dll

Syntax

public class QrReader : Object

Constructors

QrReader()

Initializes a new instance of the QrReader class.

Declaration

public QrReader()

Methods

Read(IQrInput)

Detects and reads all QR code(s) in the frame(s) of the IQrInput provided and wraps all results in a QrResult with coordinates and value information.

Declaration

public IEnumerable<QrResult> Read(IQrInput input)

Parameters

Type	Name	Description
IQrInput	input	Wrapped frame bitmap

Returns

Type	Description
System.Collections.Generic.IEnumerable<QrResult>	Object with 4 IronSoftware.Drawing.PointF coordinate values, and QR Code value

Remarks

If using the IronQr.Slim package alone without IronQr, the operation will not use the Machine Learning model to detect QR Codes resulting in a longer, lower quality read.

ReadAsync(IQrInput)

Detects and reads all QR code(s) in the frame(s) of the IQrInput provided asynchronously and wraps all results in a QrResult with coordinates and value information.

Declaration

public Task<IEnumerable<QrResult>> ReadAsync(IQrInput input)

Parameters

Type	Name	Description
IQrInput	input	Wrapped frame bitmap

Returns

Type	Description
System.Threading.Tasks.Task<System.Collections.Generic.IEnumerable<QrResult>>	A task that represents the asynchronous read operation. The value of the TResult parameter contains an object with 4 IronSoftware.Drawing.PointF coordinate values, and QR Code value.

Remarks

If using the IronQr.Slim package alone without IronQr, the operation will not use the Machine Learning model to detect QR Codes resulting in a longer, lower quality read.
