Coordinates instead of pixels

A photograph is a grid of colored pixels; enlarge it and the grid shows. A vector drawing stores geometry — this line runs from here to there, this curve bends this much, this shape is filled with this color — so the software redraws it at whatever size you ask for. That is why a vector logo prints crisply on a pen and on a billboard from the same file.

When vectors are the right choice

  • Logos, wordmarks and brand assets that will be resized forever.
  • Icons and UI graphics for the web, where SVG is the native format.
  • Cut and engrave files for vinyl cutters, laser machines and plotters, where the machine follows paths.
  • Diagrams, maps, floor plans and technical illustration.
  • Apparel and merchandise artwork: shirt prints, decals, sublimation designs.

Raster tools remain the right answer for photo retouching, painting with texture, and effects that are pixel-based by nature.

The pieces of a vector drawing

Everything you draw is either a shape or a path. Shapes stay parametric — a rectangle keeps its corner radius, a star its point count — until you convert them. Paths are sequences of nodes joined by straight or curved segments and are the general-purpose building block, described in working with paths. Each object carries a fill and a stroke, sits in a stacking order, and can be grouped or placed on a layer.

How Inkscape approaches it

Inkscape edits SVG directly rather than converting to and from its own format, so what you see on canvas maps to elements you can inspect in the built-in XML editor. Boolean operations combine shapes, Live Path Effects add non-destructive modifiers, and clones stay linked to their original so a change propagates. Vector design is largely the craft of building shapes cleanly enough that later edits stay cheap.

From bitmap to vector

Scanned sketches and simple logos can be converted with Path → Trace Bitmap. Results depend on the input: high-contrast line art traces well, photographs produce hundreds of blobby paths. Trace, then clean up nodes with Ctrl+L and rebuild the important curves by hand — a traced file that nobody tidies is usually worse than a redraw.

Output

Keep the editable master as SVG and export copies for their destination: PNG at a chosen DPI for the web and previews, PDF or EPS for print shops, DXF or plain SVG for machines. The export guide covers the settings that change results, and the software overview lists what else is in the box.
