Example for the Starburst filter

Starburst applied


This filter fills the active layer's alpha with a starburst gradient and adds a shadow.

It is derived from the Starburst script-fu (FileCreateLogosStarburst in the image window), which creates a logo from a text.

You can use this filter to create shapes filled with the above starburst motif:

The Starburst filter


This filter uses four layers (three of them will be created by the filter):

Layers after applying the Starburst filter

  • The Burst layer contains the bursting star, created by the Supernova filter.

  • The active layer was named layer #2 in the example above. It has been filled with the Crack pattern, so the content of this layer doesn't matter. Only the active layer's alpha channel does.

    画像は常に活性レイヤーの寸法と同じ大きさに変更されます。

  • The Shadow layer contains a drop shadow in the same shape but slightly extended size of the active layer's alpha channel.

  • The Background layer: this is a new layer filled with the Background color.

図16.383 Starburst options

Starburst options

Effect size (pixels * 30)

Just ignore this option. It's nonsense. (This is actually the font size option of the Starburst Script-Fu script. You can still use it to vary the offset (size) of the lower right shadow, though: effect size * 0.03.)

Burst color

This color will be passed to the Supernova filter as the color of the bursting star; it defaults to green. A click on the color swatch button brings up the color selector, where you can choose another color.

背景色

This is the color used to fill the Background layer; it defaults to white. When you click on the button, you may choose any other color in the color selector dialog.
