Inkscape - ( Open Source)
Inkscape is more than enough to create vector drawings, being based on the SVG standardized file format.
Inkscape is a program specially designed for editing or creation of vector graphics. The format used by the application is a W3C standard, SVG. It offers a large number of elements recognized by this format : basic shapes , paths, clones , transformations, Boolean operations , gradients , groups , layers. The basic functionalities of this standard are available as adding text, creating forms, duplication, transparency, changes or gradients. However Inkscape provides interesting tools such as support for metadata Creative Commons, layers, complex paths, etc.
The application also allows the import of documents in EPS, Postscript, JPEG, PNG or TIF. The backup will be in PNG format or other, depending on the future use of each image.
