Gets the number of values under the window center element.
Supported in Silverlight, Windows Phone 7.
Syntax
| Visual Basic (Usage) |  Copy Code |

Dim instance As DicomDataSet
Dim frameIndex As Integer
Dim value As Integer
value = instance.GetWindowCount(frameIndex) |
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.
Example
This example will load a DICOM dataset, extract the window center and window width and then update their values.
