SetDoubleValue(DicomElement,double[],int) Method

Summary
Sets the double values of a Data Element.
Syntax
C#
C++/CLI
Java
public bool SetDoubleValue( 
   DicomElement element, 
   double[] value, 
   int count 
) 
public boolean setDoubleValue(DicomElement element, double[] doubleValue, int count) 
public: 
bool SetDoubleValue(  
   DicomElement^ element, 
   array<double>^ value, 
   int count 
)  

Parameters

element
An item in the Data Set.

value
Buffer that contains the double value(s) to set. If you want to set multiple values in the Value Field, put all double values in value and set count to the appropriate number of values.

count
Value that represents the number of values to set in the Value Field. If you want to set multiple values in the Value Field, put all the double values in value and set count to the appropriate number.

Return Value

true if the double value were set successfully; otherwise, it is false (the double values of the Data Element could not be set).

Remarks

If you want to set more than one value in the Value Field of the Data Element, put all the double values in value and set count to the corresponding number of entries. For example, if you wish to set three double values in the Value Field of the Data Element, put the three double values in value and set count to three. If more than one value is stored in the Value Field of the Data Element, you must set all values at the same time.

This method can be called only if the Value Representation of the Data Element is DicomVRType.DS or DicomVRType.FD. For more information about Value Representations, refer to Default Value Representation Table.
