Description copied from class: AbstractIndicatorRenderer

Calculates the shape of the indicator. This is needed so that we can create a BufferedImage of the right size when generating shadows

Specified by:

calculateShape in class AbstractIndicatorRenderer<Bullet>

Parameters:

bullet - the gauge, such as an instance of Bullet

value - the value to be represented by the indicator

drawIndicator

protected void drawIndicator(Graphics2D g,
                             Bullet bullet,

paintLabel in class AbstractIndicatorRenderer<Bullet>

paintLegendItem

public Shape paintLegendItem(Graphics g,
                             Bullet bullet,
                             IndicatorStyle style,
                             int w,
                             int h)
