                   Double value)

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

calculateShape

protected Shape calculateShape(Orientation orientation,
                   double pixelValue,
                   double[] positions)
