Xfig

Xfig is an interactive drawing tool which runs under X Window System Version 11 Release 4 (X11R4) or later, on most UNIX-compatible platforms, and e.g. under Darwin on the MacIntosh and any X server under Microsoft Windows. See the installation section for details. It is freeware, and available via anonymous ftp. In xfig, figures may be drawn using objects such as circles, boxes, lines, spline curves, text, etc. It is also possible to import images in formats such as GIF, JPEG, EPSF (PostScript), etc. Those objects can be created, deleted, moved or modified. Attributes such as colors or line styles can be selected in various ways. For text, 35 fonts are available. Text can also include Latin-1 characters such as ”a umlaut” or ”c cedilla”.
