Encoder Class

Definition

An Encoder object encapsulates a globally unique identifier (GUID) that identifies the category of an image encoder parameter.

Encoder

Remarks

When you pass a parameter to an image encoder, the parameter is encapsulated in an EncoderParameter object. One of the fields of the EncoderParameter object is a GUID that specifies the category of the parameter. Use the static fields of the Encoder class to retrieve an Encoder that contains parameters of the desired category.

The image encoders that are built into GDI+ receive parameters that belong to several categories. The following table lists all the categories and the GUID associated with each category.

Constructors

Encoder(Guid)

Initializes a new instance of the Encoder class from the specified globally unique identifier (GUID). The GUID specifies an image encoder parameter category.

Fields

ChrominanceTable

An Encoder object that is initialized with the globally unique identifier for the chrominance table parameter category.

ColorDepth

An Encoder object that is initialized with the globally unique identifier for the color depth parameter category.

Compression

An Encoder object that is initialized with the globally unique identifier for the compression parameter category.

LuminanceTable

Represents an Encoder object that is initialized with the globally unique identifier for the luminance table parameter category.

Quality

Gets an Encoder object that is initialized with the globally unique identifier for the quality parameter category.

RenderMethod

Represents an Encoder object that is initialized with the globally unique identifier for the render method parameter category.

SaveFlag

Represents an Encoder object that is initialized with the globally unique identifier for the save flag parameter category.

ScanMethod

Represents an Encoder object that is initialized with the globally unique identifier for the scan method parameter category.

Transformation

Represents an Encoder object that is initialized with the globally unique identifier for the transformation parameter category.

Version

Represents an Encoder object that is initialized with the globally unique identifier for the version parameter category.

Properties

Guid

Gets a globally unique identifier (GUID) that identifies an image encoder parameter category.
