Masking fuzzy or irregular edges is typically a slow, painstaking procedure
of hand selection with the Polygon Lasso tool, or if you prefer a vector
mask, the Pen tool. Plugins that automate the process (e.g., Extensis Mask
Pro, Corel Knock Out) are expensive for one-trick ponies. And shame on
Extensis and Corel - they haven't been made available for Fireworks. This
article will teach you to quickly mask objects with irregular edges using the
new Fireworks MX 2004 Replace Color tool, a simple Alpha masking technique,
and some sneaky edgerefining tricks.
I'm going to use a gorgeous flower image (see Image I), photographed by
Daniel Reyes of Sydney, Australia, to demonstrate the technique. (If you'd
like to download a copy and follow along, go to
www.playingwithfire.com/flower.zip.) Unzip the image file, and open it in
Fireworks MX 2004.
