public double GetElementDoubleValue(
	SoDicomTag tag,
	ulong idx,
	double defaultValue
)

Public Function GetElementDoubleValue ( 
	tag As SoDicomTag,
	idx As ULong,
	defaultValue As Double
) As Double

public:
double GetElementDoubleValue(
	SoDicomTag^ tag, 
	unsigned long long idx, 
	double defaultValue
)

member GetElementDoubleValue : 
        tag : SoDicomTag * 
        idx : uint64 * 
        defaultValue : float -> float 

Parameters

tag

Type: OIV.VolumeViz.Readers.DicomSoDicomTag

The tag of the element to find.

idx

Type: SystemUInt64

The index of the scalar value to extract.

defaultValue

Type: SystemDouble

The value returned if the extraction fails.

Return Value

The double stored at the given index in the element with the given tag, or the default value if the extraction fails.

If the value is of a numeric type different from DOUBLE, it will be casted to a double. That casting may cause a precision loss.
