Decompose is an application allowing an easy and flawless extraction of elements from pictures in order to use them to make composite images. It is the perfect tool for making images for Web pages, newspapers and magazines or simply for your own creations. Extracted objects are saved as a TIFF file with transparency. Decompose also corrects colors to remove all traces of the previous background, thus generating perfect mattes.

It took me some playing around with this for quite a while to get the hang of it. When I figured it out I got really good results. After you apply the masks you need to manually fix the edges by using the erase brush with the image magnified to the maximum. Then you can switch between the foreground and background to the get the edge right down to the pixel.

The current issue of Macworld gives it a good write up.

I find that Decompose scores over Photoshop by having a brush to define the transitional edge ares where pixels may be foreground image or background.

A cut-out in PhotoShop relies on performing a very accurate selection, knocking out the background and then doing a lot of smoothing of the edges. In Decompose you make a broad-brush selection of the edge area, covering the whole border between foreground and background, from which the app. calculates which is which, removes the background to transparency and gives a smooth edge.

It seems to work well even if there isn't a lot of contrast between foreground and background. If you can see it, you can cut it out.

Well worth the money to save time and effort -- and if you need to make good quality, foolproof cut-outs in a hurry, you'll thank the developers.

I think some sensitivity controls would help, and I felt the need of grab tool with a spacebar shortcut to navigate around the image, but this is only a v1.n application and these are only minor refinements that are bound to come in future releases..

In my opinion, Decompose has got a great potential, and its results are too good to stop developing it.
