Crest (feathers) Crest (feathers) The crest is a prominent feature exhibited by several bird and other dinosaur species on their heads. The crest is made up of semiplume feathers: a long rachis with barbs on either side. These are plumulaceous feathers, meaning that they are soft and bendable. In birds, these semiplumes are common along the head, neck, and upper back, and may be used for buoyancy and sensing vibrations. Crests on birds are generally used for display purposes. Cockatoos and their smaller cousins, cockatiels, are part of the parrot family Cacatuidae found in Australia, the Bismarck Archipelago and the Philippines, and
Calamus (DTP) use optical kerning, where the shapes of the characters are analysed to determine the appropriate distances; Calamus’ approach might be regarded as a simplification of that, working with a low-resolution version of the final character. Calamus (DTP) Calamus is a desktop publishing application, built for the Atari ST computer. The first version was released on July 1, 1987 by the former German software company DMC GmbH. Calamus is still supported by its German owner company, invers Software, and also runs under a built-in and transparent Atari emulator on Windows, or on other platforms such as Mac OS 9 and Mac
