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.
