Scansoriopterygidae scansoriopterygids had a semilunate carpal (half-moon shaped wrist bone) that allowed for bird-like folding motion in the hand. Even if powered flight was not possible, this motion could have aided maneuverability in leaping from branch to branch. The adult specimen of "Epidexipteryx" lacked preserved feathers around the forelimbs, but preserved simple feathers on the body and long, ribbon-like feathers on the tail. The tail feathers, likely used in display, consisted of a central shaft (rachis) and unbranched vane (unlike the vanes of modern feathers, which are broken up into smaller filaments or barbs). "Yi" also preserves feathers. These are notably
Calamus (DTP) LE 2015 (lite edition with restricted number of modules). Calamus is a RIP itself and handles various, adjustable raster dot sizes at the same time. It handles rasterization information per document, page or even per frame. It also uses a unique, notable method of "cutting raster dots", which means that a screen raster can be cropped or clipped at certain borders, given by the document layout elements. Thus, it does not require any external RIP for interpretation, rendering and screening of documents. Using a special module, Calamus supports dot rasterization (using the term "Star Screening") which is a frequency modulated
