Parameters

HDICOMWAVEFORMCHANNEL hDICOMWaveFormChannel

A DICOM waveform channel handle.

L_BOOL bInclude

Boolean value that specifies whether the function should insert the "Filter Low Frequency" (003A,0220) element or remove it from the dataset. Possible values are:

Value	Meaning
TRUE	Insert the "Filter Low Frequency" (003A,0220) element (that corresponds to this channel) into the dataset and then set its value.
FALSE	Delete the "Filter Low Frequency" (003A,0220) element (that corresponds to this channel) from the dataset.

L_DOUBLE dLowFrequency

New filter low frequency.

Returns

Value	Meaning
TRUE	The filter low frequency was updated successfully.
FALSE	An error occurred.

Comments

This function sets the value of the "Filter Low Frequency" (003A,0220) element that corresponds to this channel. Set bInclude to TRUE to force the function to insert the element if it does not already exist in the dataset.

This function can also be used to delete the "Filter Low Frequency" (003A,0220) element that corresponds to this channel by setting bInclude to FALSE. In this case the dLowFrequency parameter is ignored.
