XnView is a cross-platform image viewer used for viewing, converting, organising and editing graphical & video files. It is free of charge for private non-commercial, educational use and non-profit organisations. It is popular with users as it provides many features normally found in commercial image viewers and it supports many image file formats that other powerful image organizers such as ACDSee do not.
Inkscape is a vector graphics editor application. It is distributed under a free software license, the GNU GPL. Its stated goal is to become a powerful graphics tool while being fully compliant with the XML, SVG, and CSS standards.Inkscape is cross-platform and runs on Mac OS X (typically under X11, although the underlying GTK+ toolkit can be compiled to run natively under Quartz), Unix-like operating systems, and Microsoft Windows. Inkscape's implementation of SVG and CSS standards is incomplete. Most notably, it does not yet support animation, or SVG fonts. Inkscape has multi-lingual support, particularly for complex scripts, something currently lacking in most commercial vector graphics applications.As of 2009, Inkscape is under active development, with new features being added regularly.
