      public SpectrogramPanel(RoccaSpecPopUp roccaSpecPopUp)
      Creates a new SpectrogramPanel for the given data matrix

  • Method Details

    • setColors

      public void setColors()
      Set the colors of the spectrogram, based on the FFT values

    • setColorOffset

      public void setColorOffset(double colorOffset)
      Updates the offset factor used to calculate brightness. Increasing this variable increases the brightness of the spectrogram, while decreasing it has the opposite effect
      Parameters:
      colorOffset - the offset factor used to calculate the brightness

    • getColorOffset

      public double getColorOffset()

    • setColorScale

      public void setColorScale(double colorScale)
      Updates the scale factor used to calculate contrast. Increasing this variable increases the contrast of the spectrogram, while decreasing it has the opposite effect
      Parameters:
      colorScale - the scaling factor used to calculate the contrast

    • getColorScale

      public double getColorScale()
