Syntax

public class JpegEncoderParameters : INotifyPropertyChanged

Constructors

JpegEncoderParameters()

Initializes a new instance of the JpegEncoderParameters class with default luminance and chrominance quantization tables.

Declaration
public JpegEncoderParameters()

Properties

ChrominanceTable

Gets or sets the 64-byte chrominance quantization table used during encoding, which influences color compression and visual quality.

Declaration
public byte[] ChrominanceTable { get; set; }
Property Value
System.Byte[]

EncodingType

Gets or sets the JPEG encoding mode (e.g., Baseline or Progressive), which determines scan layout and decoder compatibility.

Declaration
public JpegEncodingType EncodingType { get; set; }
Property Value
JpegEncodingType

LuminanceTable

Gets or sets the 64-byte luminance quantization table used during encoding, which affects detail retention and compression of brightness.

Declaration
public byte[] LuminanceTable { get; set; }
Property Value
System.Byte[]

QuantizingQuality

Gets or sets the quality factor (0–100) applied to quantization; higher values preserve detail at the cost of larger files.

Declaration
public float QuantizingQuality { get; set; }
Property Value
System.Single

SamplePrecision

Gets or sets the sample precision in bits for component values in the frame; affects encoded bit depth.

Declaration
public int SamplePrecision { get; set; }
Property Value
System.Int32

Remarks

CCITT T.81, Annex B, section B.2.2 Frame header syntax (see P parameter in the Table B.2).

Events

PropertyChanged

Raised when any encoder parameter changes; use to react to updates that affect encoding output.

Declaration
public event PropertyChangedEventHandler PropertyChanged
Event Type
System.ComponentModel.PropertyChangedEventHandler
