Example for the “Chrome” filter
This filter is derived from the “Chrome” logo script
( → → →
in the image window), which – according to the script author – creates a
“simplistic, but cool, chromed logo” (see above).
The filter adds this simple chrome effect to the alpha, that is the area
of the active layer defined by the non-transparent pixels (think of it
as a “selection by visibility”). The filter effect will
always be applied according to the alpha values.
Apparently the effect only looks “cool” when the filter is
applied to thin areas. For wide shapes you can try to increase the
Offset value; see the examples
The image will always be resized to the active layer's size.
