  • Method Details

    • new2DData

      public void new2DData(DataUnit2D fftDataUnit)

    • reBuildImage

      public void reBuildImage()

    • reBuildImage

      protected boolean reBuildImage(javafx.concurrent.Task<Boolean> task)
      Call to re build the image, for example if colour map or amplitude scale changes. Note: Do not run a seperate thread if the image is running in real time mode. Can be used on thread if image is paused or in viewer mode. During rebuilding in real time mode some data may be lost
      Parameters:
      if - on a separate thread input which task this function is a part of. Means the rebuild can be cancelled. Can null
      Returns:
      true if image was completely rebuilt.

    • resetForLoad

      public void resetForLoad()
      Reset anything necessary before new data are loaded offline in viewer mode.

    • resetForLoad

      public void resetForLoad(boolean newWritableImage)
      Reset anything necessary before new data are loaded offline in viewer mode.

    • getFftHop

      public int getFftHop()
      Get the current FFT hop size in bins (samples) for this spectrogram plot.
      Returns:
      FFT hop size in bins (samples)

    • rebuildFinished

      public void rebuildFinished()

    • setFreqLimits

      @Deprecated public void setFreqLimits(javafx.beans.property.DoubleProperty[] frequencyLimits)
