Inkscape is an open source vector graphics editor
Inkscape is an Open Source vector graphics editor, with capabilities similar to non open editors using the W3C standard Scalable Vector Graphics (SVG) file format.
Supported SVG features include shapes, paths, text, markers, clones, alpha blending, transforms, gradients, patterns, and grouping.
Inkscape also supports Creative Commons meta-data, node editing, layers, complex path operations, bitmap tracing, text-on-path, flowed text, direct XML editing, and more.
It imports formats such as JPEG, PNG, TIFF, and others and exports PNG as well as multiple vector-based formats.
You can easily run Inkscape INSIDE a VMware Player Ubuntu virtual machine EVEN if you are not running GNU/Linux directly on your desktop !
