Inkscape - Free to download and use
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.
This illustration of a Ferrari by Gilles Pinard was done by hand without any tracing. Gradients, blurs, and other various other techniques really bring this image to life.
|After many years and countless requests, Inkscape 0.48 now supports editing multiple paths at the same time. Previously editing with the Node Tool had a limitation of working with only one path at a time. Thanks to happyline for the wonderful example screenshot.|
|Inkscape 0.48 has added a Spray Tool to quickly and easily spray multiple copies of items. With the parameters for rotation and size it allows creating effects that previously would take much longer to achieve. Thanks to DiSmeCha|
