    • pixelsToUnits

      public static java.awt.geom.Point2D pixelsToUnits​(java.awt.Graphics2D g, int x, int y)
      Transforms pixels to time and frequency.
      Parameters:
      g - The current graphics, with a meaningful transform applied to it.
      x - The x coordinate, in pixels.
      y - The y coordinate, in pixels.
      Returns:
      A point with time (in milliseconds) as x coordinate, and frequency (in cents) as y coordinate.

    • pixelsToUnits

      public static float pixelsToUnits​(java.awt.Graphics2D g, int pixels, boolean horizontal)
      Transforms a number of pixels into a corresponding time or frequency span. E.g. 10 horizontal pixels could translate to 320 milliseconds. 10 vertical pixels could translate to 32cents.
      Parameters:
      g - The current graphics, with a meaningful transform applied to it.
      pixels - The number of pixels
      horizontal - Is it the horizontal or vertical axis?
      Returns:
      A number of cents or milliseconds.
