示例1: _computed_image_dimensions

  _computed_image_dimensions(): {height: number, width: number} {
    /*
    Heuristics to determine ColorBar image dimensions if set to "auto"

    Note: Returns the height/width values for the ColorBar's scale image, not
    the dimensions of the entire ColorBar.

    If the short dimension (the width of a vertical bar or height of a
    horizontal bar) is set to "auto", the resulting dimension will be set to
    25 px.

    For a ColorBar in a side panel with the long dimension (the height of a
    vertical bar or width of a horizontal bar) set to "auto", the
    resulting dimension will be as long as the adjacent frame edge, so that the
    bar "fits" to the plot.

    For a ColorBar in the plot frame with the long dimension set to "auto", the
    resulting dimension will be the greater of:
      * The length of the color palette * 25px
      * The parallel frame dimension * 0.30
        (i.e the frame height for a vertical ColorBar)
    But not greater than:
      * The parallel frame dimension * 0.80
