public: double[] GetDoubleValue( DicomElement* element, int index, int count ) |
Parameters
- element
- An item in the Data Set.
- index
- The zero-based index of the first value to retrieve, when more than one value is stored in the Value Field.
- count
- Value that represents the number of values to retrieve when more than one value is stored in the Value Field. In most instances you will only retrieve one value so this parameter will be equal to one.
Return Value
A buffer to a double value stored in the Value Field of the specified Data Element. null if The length of the Value Field is 0, the method was called for the incorrect Value Representation type, or the method was called for a folder (sequence) element.For an example, refer to SetIntValue.
If you have more than one value stored in the Value Field of the specified Data
Element, you can retrieve one or more of those elements. For example, if the Value
Field of the specified Data Element contains three double values, and you are only
interested in retrieving the last two double values, set index
to 1 and count to 2. This tells the method to retrieve
the double values starting at position 1 (the index is zero-based) and retrieve two
values. Therefore you would retrieve the values in positions 1 and 2 in the Value
Field.
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.
