GetByteValuePtr(DicomElement,Int32,UInt32) Method
Summary
Returns a pointer to a byte value that is stored in the Value Field of the specified element.
Syntax
public IntPtr GetByteValuePtr(Leadtools.Dicom.DicomElement element,int index,uint count)
Public Overloads Function GetByteValuePtr( _ByVal element As Leadtools.Dicom.DicomElement, _ByVal index As Integer, _ByVal count As UInteger _) As IntPtr
public IntPtr GetByteValuePtr(Leadtools.Dicom.DicomElement element,int index,uint count)
function Leadtools.Dicom.DicomDataSet.GetByteValuePtr(DicomElement,Int32,UInt32)(element ,index ,count)
public:IntPtr GetByteValuePtr(Leadtools.Dicom.DicomElement^ element,int index,uint 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 pointer to a byte value stored in the Value Field of the specified Data Element. Alternatively, it returns an IntPtr.Zero 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.
Remarks
If you have more than one value stored in the Value Field of the specified Data Element, you can retrieve one or more than one of those elements. For example, if the Value Field of the specified Data Element contains three byte values, and you are only interested in retrieving the last two byte values, set index to 1 and count to 2. This tells the method to retrieve the byte 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.OB, DicomVRType.SQ, or DicomVRType.UN. For more information about Value Representations, refer to Default Value Representation Table.
