Parameters

channel

Type: SystemInt32
The channel for which to create the spectrum graph.

g

Type: System.DrawingGraphics
The GDI+ graphics object where to draw the wave form (ie. can be taken directly from a PaintEventArgs).

clipRectangle

Type: System.DrawingRectangle
The rectangle describing the size of the wave form to draw (ie. can be taken directly from a PaintEventArgs).

color1

Type: System.DrawingColor
The base color (normal) for the FFT data.

color2

Type: System.DrawingColor
The peak color for the FFT data.

background

Type: System.DrawingColor
The background color to be used when drawing the image.

linear

Type: SystemBoolean
, if linear scaling (see ScaleFactorLinear) should be applied to the FFT data. , to scale by Sqr (see ScaleFactorSqr) to make low values more visible (recommended).

fullSpectrum

Type: SystemBoolean
, if the full frequency spectrum should be shown (across the whole width of the image). , if the width of the image should be use (in this case as much frequencies are shown - starting with the lower values - as fit into the width).

highQuality

Type: SystemBoolean
, if anti alias should be used when drawing. will draw in high speed mode.
