Use the Edit > Fractal Type function or the popup button of the Fractal Type property on the
Parameters page to change the fractal set and formula.
The available fractal sets are: Mandelbrot and Julia (for a given point).
The formula can be changed by selecting a variant and an exponent. The Integral Exponent field allows one to select an exponent ranging from 2 to 6, which is calculated using a fast, predefined algorithms. The Real Exponent field allows entering a fractional number, but a significantly slower algorithm is used.
You can save the current fractal type and position using the Position > Save Bookmark command and restore it later using Position >
