Eyedropper

Another tool to choose new parameter values is the Eyedropper feature. It is similar to the 

Explore

feature, but it selects parameter values from the coordinates in the fractal window, instead of using a 

separate coordinate grid. This is useful if the fractal coordinates have a relationship with the 

parameter that you are working with.

For example, to choose new values for the Julia Seed parameter of a 

Julia set

, open a separate 

fractal window with the 

Mandelbrot set

, and use the Eyedropper feature to pick values from the 

Mandelbrot fractal, as an alternative for 

Switch mode

.

If you click on a parameter to give it the keyboard focus, a small window will pop up below the input 

box with two buttons. These invoke the Explore and Eyedropper features.

Click the Eyedropper button to start eyedropper mode.

As you move the mouse cursor over a fractal window, you see the fractal coordinates for the point 

under the mouse cursor in the input box for the parameter that is in eyedropper mode. You can 

select coordinates from any fractal window, not just the active window.

Look at the 

Fractal Mode

 tool window for a live preview of the active fractal layer with the current 

parameter value. Simply click inside the fractal window to select the new parameter value.

The Eyedropper feature works with complex, floating point, integer, and color parameters. With 

floating point and integer parameters, only the real part of the fractal coordinates is used.

To use the eyedropper with color parameters, right click the color parameter and click Eyedropper. 

You can select colors from any fractal window or gradient editor.

Notes

G     

To cancel without selecting a new parameter value, click on the eyedropper icon that has 

appeared in the input box for the parameter that is in eyedropper mode.

Another way to start the eyedropper is by right clicking a parameter and selecting 

Eyedropper from the menu that pops up.
