Kevin,
From the tool palette, select "Color keyed selection" and the "Exclude area"
logical button.
Select "Process/Standard adj/HSV Set". Set R, G, B and Var to zero. Click on
"Key on RGB" for faster processing. Click on Done.
Imagemaster will select all pixels which do _not_ fall inside the color range,
i.e. everything except (0,0,0).
The next requester asks what to do with those pixels: Hue should be off, Sat
should be applied with a value of 0, and Lum should be applied with a value of
255. Click on Done.
Presto! Imagemaster whitens everything that wasn't black.
For a softer keying solution, check out the macro I'll be uploading in a few
days. It creates antialiased alpha channels, so you'll lose that jaggy border
when you superimpose those trees.
Blaq!
