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.
