Inkscape is a vector-based drawing program, like CorelDraw® or Adobe
Illustrator® from the proprietary software world, and Sketch or Karbon14 from
the free software world. It is free software, distributed under the terms of
the Gnu General Public License, Version 2.
Inkscape uses W3C SVG as its native file format. It is therefore a very useful
tool for web designers and as an interchange format for desktop publishing.
It has a relatively modern display engine, giving you finely antialiased
display, alpha transparencies, vector fonts and so on. Inkscape is written in
C and C++, using the Gtk+ toolkit and optionally some Gnome libraries.
