Design and illustration software can offer a wide range of tools, but commercial applications can also be expensive. Adobe Illustrator has long been a familiar choice for illustrators and designers. The original article introduced a free, open-source alternative: Inkscape.
Inkscape provides tools for creating and editing vector artwork without a software licence fee. It is an alternative worth exploring when you need to draw illustrations, diagrams, icons or other artwork that can be resized.
A range of drawing tools
The original article highlighted Inkscape's availability across Windows, macOS and Linux. For a current installation, check the supported operating systems and packages on the official Inkscape website; the old Windows 2000, 2003 and XP examples in the source are historical.
Its vector-editing tools include SVG support, markers, clones, transparency, node editing, bitmap tracing and operations on paths. These tools let you work with individual shapes and curves rather than treating the entire drawing as a fixed grid of pixels.
Vector graphics and bitmap images
Bitmap editors such as Photoshop and GIMP work primarily with images stored as pixels. A bitmap has a particular resolution, so enlarging it can reveal the underlying pixel grid.
A vector drawing describes shapes, lines and curves mathematically. A renderer uses those descriptions to draw the artwork at a chosen resolution or zoom level. This makes vectors useful for work that needs to appear at several sizes.
The distinction is about how the artwork is represented, rather than a guarantee that every imported image will scale perfectly. A photograph embedded in a vector document is still a bitmap.
Getting started
Digital drawing tools can feel unfamiliar at first. Begin with a simple document, practise drawing and editing a few shapes, then explore paths, text and SVG export. Inkscape offers a way to learn those techniques without buying a commercial illustration package.
