#### 16.3.1. Overview

Figure 16.337. Example for the “Alien Glow” filter

“Alien Glow” applied

This filter adds an eerie glow around the active layer's alpha.

| Warning
The image will always be resized to the active layer's size.

The filter is derived from the “Alien Glow” script (File → Create → Logos → Alien Glow in the image window), which creates the following text effect:

The “Alien Glow” Script-Fu script.

Reproducing this glow is easy:

- If necessary, create a selection from the alpha channel of the active layer.

- Fill the selection with the following Gradient Blend: Shape = Shaped (spherical); Gradient = FG to BG (RGB), with FG = dark gray (79,79,79), BG = black.

- Create a new layer (“Alien Glow”) below. Extend the selection slightly, feather it, and fill it with the Glow color.

- Create a new background layer filled with black.

#### 16.3.2. Activate the filter

You can find this filter in the image window menu under Filters → Alpha to Logo → Alien Glow.

#### 16.3.3. Options

Figure 16.338. “Alien Glow” options

Glow size (pixels * 4)

  This is actually the font size option of the “Alien Glow” Script-Fu script. However, two values will be set in relation to this size: the glow will be enlarged by “Glow size” / 30, and feather radius is “Glow size” / 4. You should probably choose the height of your objects for this option (ignore “pixels * 4”).

Glow color

  This is the color of the “eerie” glowing. Of course it defaults to green (63,252,0), but a click on the swatch button brings up the color selector where you can choose any color.
