Preview domain

Uncheck the Real time preview only if your computer is slow. In this case, you can update preview by clicking on the Redraw button.

By clicking-dragging mouse pointer on preview, you can draw a rectangle delimiting an area which will be zoomed.

Zoom

You have there some options to zoom in or zoom out. The Undo allows you to return to previous state, before zooming. The Redo allows you to reestablish the zoom you had undone, without having to re-create it with the zoom-in button.

Parameters tab

This tab contains some options to set fractal calculation and select fractal type.

Fractal Parameters

here, you have sliders and input boxes to set fractal spreading, repetition and aspect.

XMIN; XMAX; YMIN; YMAX

You can set fractal spreading between a MINimum and a MAXimum, in the horizontal (X) and/or vertical (Y) directions. Values are from -3.0 to 3.0.

ITER

With this parameter, you can set fractal iteration, repetition and so detail. Values are from 0.0 to 1000.0

CX; CY

With these parameters, you can change fractal aspect, in the horizontal (X) and/or vertical (Y) directions, except for Mandelbrot and Sierpinski types.

Open; Reset; Save

With these three buttons, you can save your work with all its parameters, open a previously saved fractal, or return to the initial state before all modifications.

Fractal type

You can choose what fractal type will be, for instance Mandelbrot, Julia, Barnsley or Sierpinski.

Colors tab

This tab contains options for fractal color setting.

Fractals tab

This tab contains a big list of fractals with their parameters, that you can use as a model: only click on the wanted one.

The Refresh allows you to update the list if you have saved your work, without needing to re-start GIMP. You can delete the selected fractal from the list by clicking on the Delete.
