Example for the “Chip Away” filter
This filter adds a chipped woodcarving effect to the alpha channel of
the active layer. Optionally it adds a drop shadow to the image.
The content of the active layer doesn't matter, only the shape of its
alpha channel does.
The image will always be resized to the active layer's size.
The filter is derived from the “Chip Away” Script-Fu script
( → → → in the image window),
which creates a text effect like that:
To achieve a chipping effect, the filter creates a selection from the alpha
channel in a new layer, fills the selection with white, spreads the pixels, and applies a Gaussian blur to the layer. Then it uses
this layer as a Bump map,
creating a 3D effect.
Activate the filter
This filter is found in the image window menu under
→ → .
“Chip Away” options
This option lets you vary the size of chipping area. But note that
“Chip amount” is not the size of this area in pixels.
It is used as the maximum amount pixels are randomly spread by the
Spread filter applied to the
bump map. Valid range is 0-200.
“Chip amount” examples
The specified value will be passed as “Radius” option
to the Gaussian blur filter,
which will blur the bump layer by this amount.
If checked, the bump map
will be inverted and will create hollows instead of bumps, which
makes the image looking carved.
“Chip Away” inverted example
If checked, a Drop
shadow will be added to the image in a new layer below the
Keep bump layer
By default, the bump map
used to create the chipping effect will be removed after applying
the filter. When this option is checked, the bump map will be kept
as an invisible layer.
Fill BG with pattern
If checked, the background layer (added by the filter) will be
filled with the specified Pattern. Otherwise,
it will be filled with white.
Whether or not to remove the background layer. This option is
checked by default. You can, of course, remove this layer (or
toggle its visibility) later in the
This option consists of a preview area, which will produce a popup
preview when you click on it and hold down the mouse button, and a
button. The button will popup a
dialog where you can select patterns.
The default pattern is “Burlwood”. Apart from that
one, the plug-in author suggests the patterns
“Dried mud”, “3D Green”, and
