Encoder

注解

向图像编码器传递参数时,该参数将封装在 EncoderParameter 对象中。When you pass a parameter to an image encoder, the parameter is encapsulated in an EncoderParameter object. 对象的一个字段 EncoderParameter 是 GUID,它指定参数的类别。One of the fields of the EncoderParameter object is a GUID that specifies the category of the parameter. 使用类的静态字段 Encoder 来检索 Encoder 包含所需类别的参数的。Use the static fields of the Encoder class to retrieve an Encoder that contains parameters of the desired category.

GDI + 中内置的图像编码器接收属于多个类别的参数。The image encoders that are built into GDI+ receive parameters that belong to several categories. 下表列出了所有类别以及与每个类别关联的 GUID。The following table lists all the categories and the GUID associated with each category.
