"For the benefit of the complete beginner: Inkscape is a vector drawing program. That means that it creates graphics which can be scaled without adverse effect on quality. These won’t be photos or other such graphic work, but more usually they are found in logos, clipart and other places where the image may be scaled up or down. If you enlarge a small photo or bitmap image you get pixelisation and “jaggies”. Do that with a vector graphic and you’ll find the linework is as smooth as the smaller version. Inkscape uses the open standard Scalable Vector Graphic format (svg), but it will import popular vector formats like Adobe Illustrator and wmf."
