Inkscape is a Free and open source vector graphics editor. It offers a rich set of features and is widely used for both artistic and technical illustrations such as cartoons, clip art, logos, typography, diagramming and flowcharting. It uses vector graphics to allow for sharp printouts and renderings at unlimited resolution and is not bound to a fixed number of pixels like raster graphics. Inkscape uses the standardized SVG file format as its main format, which is supported by many other applications including web browsers.
SVG Features include basic shapes, paths, text, markers, clones, alpha blending, transforms, gradients, and grouping. In addition, Inkscape supports Creative Commons meta-data, node-editing, layers, complex path operations, text-on-path, and SVG XML editing. It also imports several formats like EPS, Postscript, JPEG, PNG, BMP, and TIFF and exports PNG as well as multiple vector-based formats.
Inkscape's main motivations are to provide the Open Source community with a fully W3C compliant XML, SVG, and CSS2 drawing tool emphasizing a lightweight core with powerful features added as extensions, and the establishment of a friendly, open, community-oriented development processes.
