Public Function GetChannelSamplesPtr() As IntPtr

'Usage
 
Dim instance As DicomWaveformChannel

value = instance.GetChannelSamplesPtr()

A buffer that holds the samples (data) for a waveform channel.

This method returns a pointer to a buffer that holds the channel samples (data).
Please note that the data is always encapsulated as 32-bit regardless of the bits allocated for the channel (8- or 16-bit). You can tell if the data for the channel is 8- or 16-bit from the waveform sample interpretation. For 8-bit channels the "Waveform Sample Interpretation" (5400,1006) can either be is signed 8-bit linear DicomWaveformSampleInterpretationType.Signed8BitLinear, unsigned 8-bit linear DicomWaveformSampleInterpretationType.Unsigned8BitLinear, 8-bit mu-law DicomWaveformSampleInterpretationType.Mulaw8Bit or 8-bit A-law DicomWaveformSampleInterpretationType.Alaw8Bit. For 16-bit channels the "Waveform Sample Interpretation" can either be signed 16-bit linear DicomWaveformSampleInterpretationType.Signed16BitLinear or unsigned 16-bit linear DicomWaveformSampleInterpretationType.Unsigned8BitLinear. To get the waveform sample interpretation, use the DicomWaveformGroup.GetSampleInterpretation method.

For an example, refer to WaveformGroupCount.
