public int GetWindowCount(
int
)
'Declaration
Public Function GetWindowCount( _
ByVal As Integer _
) As Integer
'Usage
Dim instance As DicomDataSet
Dim frameIndex As Integer
Dim value As Integer
value = instance.GetWindowCount(frameIndex)
public int GetWindowCount(
int frameIndex
)
public int getWindowCount(int frameIndex)
function Leadtools.Dicom.DicomDataSet.GetWindowCount(
frameIndex
)
public:
int GetWindowCount(
int
)
Parameters
- frameIndex
- A zero-based index that identifies the frame number in the dataset. If the dataset does not support Multi-frames, this parameter is ignored.
Return Value
The number of values under the window center element.
This example will load a DICOM dataset, extract the window center and window width and then update their values.
