PATHS One nice thing about paths is that they use very few resources, especially in comparison with images. Representing a path in RAM requires storing only the coordinates of its anchors and however, is another question. Even a path with thousands of segments consumes minimal resources in comparison to a typical layer or channel. Paths can be created and manipulated using the Path tool. 7.5.3

Photoshop are already there in Gimp, or they can be downloaded from http://registry.gimp.org at no cost. • Gimp’s plug-ins are often much more powerful than Photoshop’s. We are not saying that all Gimp res- olution scanners can have very different price tags. The more expensive ones (besides the added cost of a well-known brand) are most likely to have much better CCD, lamp, optical lenses and mechanics /etc/services to tell which port to use when you want Sane to start up (the closest non-technical comparison would be a door; in order to talk to the right person, you must know on which door you should knock)
