Encoder Class

 

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

Namespace:   System.Drawing.Imaging
Assembly:  System.Drawing (in System.Drawing.dll)

public sealed class Encoder

NameDescription
System_CAPS_pubmethodEncoder(Guid)

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

NameDescription
System_CAPS_pubpropertyGuid

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

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubfieldSystem_CAPS_staticChrominanceTable

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

System_CAPS_pubfieldSystem_CAPS_staticColorDepth

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

System_CAPS_pubfieldSystem_CAPS_staticCompression

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

System_CAPS_pubfieldSystem_CAPS_staticLuminanceTable

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

System_CAPS_pubfieldSystem_CAPS_staticQuality

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

System_CAPS_pubfieldSystem_CAPS_staticRenderMethod

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

System_CAPS_pubfieldSystem_CAPS_staticSaveFlag

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

System_CAPS_pubfieldSystem_CAPS_staticScanMethod

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

System_CAPS_pubfieldSystem_CAPS_staticTransformation

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

System_CAPS_pubfieldSystem_CAPS_staticVersion

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

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.
