SetChannelSamples32(IntPtr,int) Method

Summary

Sets 32-bit data for a channel.

Syntax

C++

public int SetChannelSamples32( 
   IntPtr samples, 
   int count 
)

Public Overloads Function SetChannelSamples32( _ 
   ByVal samples As IntPtr, _ 
   ByVal count As Integer _ 
) As Integer

public: 
int SetChannelSamples32(  
   IntPtr samples, 
   int count 
)

samples
Buffer that holds the new channel sample.

count
Size of the channel sample buffer.

The actual number of samples set for the channel.

Remarks

This method sets the new samples for a channel. Before calling the SetChannelSamples32 method, be sure to call SetSampleInterpretation to set the waveform sample interpretation.
The number of samples actually set will be less than or equal to the "Number of samples per channel" (003A, 0010) in the multiplex group that represents the parent of this channel. To get that number, call the GetNumberOfSamplesPerChannel method.
In DICOM, a waveform channel can have either 8-bit or 16-bit samples (32-bit samples are not defined yet). When calling this method the data is automatically converted based on the "Waveform Sample Interpretation" (5400,1006). 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.
