What are vector lines in images?
The term "vector" in graphic design refers to a method of editing and file storage different than that of a bitmap format or editor. Vector files store information using paths, trajectories, and nodes; while bitmaps store information in an array or matrix.Furthermore, a vector illustration can be exported easily to a bitmap format, at which point it becomes un-editable using vector techniques. A bitmap can also be translated into a vector format, but that requires much more fine tuning and, in many cases, manual conversion via tracing.
