Definition

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

Namespace
xtd::drawing::imaging
Library
xtd.drawing
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.
