EncoderParameter

Synopsis

This class encapsulates a parameter to pass to a GDI+ image-storage codec when saving an image using the Image.Save() method. This can give you control over a number of different aspects of the image storage process, as enumerated in the Encoder class.

You can determine the Encoder category defining the property that the parameter affects (such as the Quality of the stored image). The Type and ValueType properties curiously both get the same information: the type of the data stored in the parameter (as listed in the EncoderParameterValueType enumeration).

You can also determine the count of the data values in the parameter using the NumberOfValues property.

The values themselves can only be set in the constructor of the parameter. Some of these common values are listed in the EncoderValue enumeration.
