Using Masks and Layers—Painting, Filling, and Color Tools - GIMP 2.6 for Photographers: Image Editing with Open Source Software - page 256

Repeat these processes if you wish to increase the brilliance, modify the
position of the highlight, or set another highlight. From the Filters menu,
simply select the Repeat Last option (if you want to repeat the exact process)
or one of the filter options.
Yet another filter you can use to produce sparkling effects on a shiny
surface is the Sparkle filter ( Filters > Light and Shadow > Sparkle ). To start, just
select the filter and use it with the default settings by clicking OK . The effect
should be a brighter, soft, sparkling contour of the wine glass, if you apply it
to the respective layer. If the effect is not strong enough, increase the values
for Flare intensity and Spike length and also for Transparency .
When you're done working with filter effects, save your image.

3.11.7 Paths and Text

In section 3.7.3, I mentioned the tool settings Text along Path and Path from
Text . In this section, I will present two examples that will show you how to
work with them.

Text along Path

In the bluesky.xcf image, create a new layer called text on circle . The text from
the path will be filled in here. Next create a circle from the Ellipse Select tool
(hold down the Shift key as you use the tool to create a circle). After that, select
To Path from the Select menu. A circular path is created that you can set to
visible with the eye symbol in the Paths dialog. Give it the name circle . Then
delete the selection by choosing Select > None . Now you can write the actual
text with the Text tool .
In Figure 3.71, you can see the font characteristics that I have chosen and
the result of clicking on the Text along Path button in the tool options of the
Text tool .
The generated text layer can immediately be made invisible again (using
the eye symbol) because it is not needed. Instead, activate the text on circle
layer that is, in contrast to the text layer, the same size as the image. Therefore,
the entire image size can be used later for filling. Next, connect the paths in
the Paths dialog using the chain symbol to the left of the preview image in
the Layers dialog. This way, they can be scaled and rotated together using the
Scale and Rotate tools. In the tool settings of the Scale tool you must select
Transform: Path . To keep the paths aspect ratio fixed while scaling them, you
must select the Keep aspect check box at the bottom of the tool settings.
Alternatively, you can press Shift during the transformation. Use the same
settings for rotating and positioning with the Move tool .

• NOTE
Actually, to fill up the circle with text,
I had to create two different paths of
text, which I had to align afterward.
