The technique of using layers in art goes back a long way. We'll also briefly examine some iPad drawing apps. Part two (coming in September) looks at Adobe Illustrator and two simpler desktop applications - Microsoft's Visio and LibreOffice Draw. Part one of this article looks at the history and background of vector image creation and examines Inkscape, an open-source application, and CorelDRAW, a proprietary program. As a result, highly detailed vector images can take a long time to render and redraw. The advantage of vector images are that they scale well and have an efficient memory footprint, although they are also processor-intensive. In this case the software takes the place of the commercial artist's drafting table and borrows terminology and techniques from that world. With vector graphics, the image is usually created entirely within the software application. With digital photography such programs replace the earlier darkroom processes used for film, and the software borrows workflows and terminology from that earlier technology. In the first of this 'FOSS v proprietary' series we looked at some of the best software for editing and manipulating bitmap images ![]()
