[GM-apis] Adding a little noise

[Paul S. <wog...@ya...>]

I am using Magick++

I would like to add some noise to an image, but the addNoise function adds
far too much noise.  

Using convert you can use -attenuate to cut it back, so how do we do this
with Magick++ which has no -attenuate option.

I'm an old film guy and the addNoise makes it look like you took 35mm Tri-X,
pushed it about 4 stops then blew it up to about 16x20...   


I'm more interested in grain that is barely noticeable.  

Any one have any ideas?
