GetChannelSamplesPtr Method

Summary

Gets the samples (data) for a waveform channel

Syntax

WinRT C#

C++

public IntPtr GetChannelSamplesPtr()

Public Function GetChannelSamplesPtr() As IntPtr

public IntPtr GetChannelSamplesPtr()

 function Leadtools.Dicom.DicomWaveformChannel.GetChannelSamplesPtr()

public: 
IntPtr GetChannelSamplesPtr();

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

Remarks

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-bit or 16-bit). You can tell if the data for the channel is 8-bit 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 GetSampleInterpretation method.
