This enumeration provides values that are used with elements from the EncoderValueenumeration to describe the properties of an image encoder in an EncoderParameterobject.

Syntax 

enum EncoderParameterValueType {
  EncoderParameterValueTypeByte		= 1,
  EncoderParameterValueTypeASCII		 = 2,
  EncoderParameterValueTypeShort		 = 3,
  EncoderParameterValueTypeLong		= 4,
  EncoderParameterValueTypeRational	= 5,
  EncoderParameterValueTypeLongRange	 = 6,
  EncoderParameterValueTypeUndefined	 = 7,
  EncoderParameterValueTypeRationalRange = 8
};

Elements

EncoderParameterValueTypeByte

Indicates that the parameter is an 8-bit unsigned int.

EncoderParameterValueTypeASCII

Indicates that the parameter is an 8-bit byte containing one 7-bit ASCII code and is NULL terminated.

EncoderParameterValueTypeShort

Indicates that the parameter is a 16-bit unsigned int.

EncoderParameterValueTypeLong

Indicates that the parameter is a 32-bit unsigned int.

EncoderParameterValueTypeRational

Indicates that the parameter is two long values that should be interpreted as a fraction.

The first long value is the numerator; the second long value is the denominator.

EncoderParameterValueTypeLongRange

Indicates that the parameter is two long values that define a range of integer values.

The first long value specifies the low end of the range; the second long value specifies the high end of the range. The range includes both end values.

EncoderParameterValueTypeUndefined

Indicates that the parameter is an 8-bit byte that can be interpreted in any way.

EncoderParameterValueTypeRationalRange

Indicates that the parameter is two rational numbers, defined by EncoderParameterValueTypeRational, that define a range of rational numbers.

The first rational value specifies the low end of the range; the second value specifies the high end of the range. The range includes both end values.
