Inkscape
Vector graphics editor

An Open Source vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format.

Inkscape supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more. We also aim to maintain a thriving user and developer community by using open, community-oriented development.

Features inside :
Object creation such as Paths, Rectangles, Text, etc. Object manipulation, Styling objects, Operations on paths, Rendering

Inkscape now also features Spiro curves (Cornu spirals) introduced to design world by Raph Levien. While FontForge is the first (open source) project that has implementation of Spiro, Inkscape provides a number of features unmatched by other tools, as demonstrated by Andy Fitzsimon. Spiro curves are implemented as a live path effect and can be applied to any existing Bezier path of be drawn from scratch with either Pen or Pencil tool.
