Hi,
If you set any of the noisify parameters to 0.0, the plugin doesn't set
the destination pixel, so it just contains uninitialised data. You can
see this by opening a new image, add an alpha channel, run noisify, move
the alpha parameter to 0.0, and go. You should end up with a
transparent image, when it shouldn't have changed the alpha channel at
all.
