Layer 4   Gaussian Integer

We are almost ready to learn about masking, but first we need to add one more layer.

In the Layers tab of the Fractal Properties tool window, Add a new layer and Rename it 

  Gaussian Integer.

G     

Replace the current Outside coloring with 

Gaussian Integer.

No changes to the parameters are needed but we do 

need to work with the gradient a bit. Many of the control 

points we added in the last layer are not needed here.

Gaussian Integer

 coloring algorithm

We want to keep the first two control points on the left 

side of the gradient. They are, respectively, bluish 

purple/opaque and black/opaque.

We will not need the third (black/transparent) point, so click on it, right click in the 

  gradient editor, and select Delete from the menu.

We also want to keep the black/opaque point at the very 

right of the gradient editor. But we can delete the group 

of four points that control the scalloped frame.

Most right click commands are also 

available in the Gradient pull down 

G     

Ctrl click to select each of them, right click in 

the gradient editor and select Delete from the 

menu and on the toolbar.

menu.

Now, to make the little dots in the image a little bigger, click and drag the second (black) 

control point to the right, somewhere around the Position of 40.
