Copyright © 2006-2019 MultiMedia Soft SPECTR_ENH_WAVE_SETTINGS structure

The SPECTR_ENH_WAVE_SETTINGS data structure (defined as SPECTR_ENH_WAVE_SETTINGS_DLL when used for COM interoperability) describes the graphical settings applied to the spectrum wave displayed on the spectrum analyzer. The current settings can be obtained through the SpectrumEnh.SettingsWaveGet method and modified through the SpectrumEnh.SettingsWaveSet method.

 

For further details about using the Enhanced Spectrum Analyzer refer to the SpectrumEnh section.

For details about using the Enhanced Spectrum Analyzer refer to the How to use the Enhanced Spectrum Analyzer tutorial.

Below you can see an image of the enhanced spectrum analyzer evidencing some of the configurable elements:

 

 

In the image above the left channel, which is represented on top respect to the right channel, is rendered through the cyan line and through the blue area while the left channel, partially covered by the left channel, is rendered through the red line and through the darker red area; the portion of right channel area covered by the left channel's area is rendered in violet.

As you can see, frequency and dB grids are still partially visible also when covered by channels areas: this is obtained by rending areas in transparency through the setting of the nAreaTransparency field: in this case the value was set to 25.
