L_DicomChannelSetSamples32

Summary

Sets the data for a channel.

Syntax

#include "Ltdic.h"

L_LTDIC_API L_UINT32 L_DicomChannelSetSamples32(hDICOMWaveFormChannel, pSamples, uCount)

Parameters

HDICOMWAVEFORMCHANNEL hDICOMWaveFormChannel

A DICOM waveform channel handle.

L_INT32 * pSamples

Pointer to the buffer that holds the new channel samples.

L_UINT32 uCount

Size of the buffer pointed to by pSamples.

Returns

The actual number of samples set for the channel.

Comments

Before calling the L_DicomChannelSetSamples32 function, be sure to call L_DicomWaveGrpSetSampleInterpretation 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, you can call L_DicomWaveGrpGetNumberOfSamplesPerChannel.

In DICOM, a waveform channel can have either 8- or 16-bit samples (32-bit samples are not defined yet). When calling this function 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 signed 8-bit linear (DICOM_SAMPLE_INTERPRETATION_SB), unsigned 8-bit linear (DICOM_SAMPLE_INTERPRETATION_UB), 8-bit mu-law (DICOM_SAMPLE_INTERPRETATION_MB) or 8-bit A-law(DICOM_SAMPLE_INTERPRETATION_AB). For 16-bit channels the "Waveform Sample Interpretation" can either be signed 16-bit linear (DICOM_SAMPLE_INTERPRETATION_SS) or unsigned 16-bit linear (DICOM_SAMPLE_INTERPRETATION_US). To get the waveform sample interpretation, use the L_DicomWaveGrpGetSampleInterpretation function.
