viivistest

Viivistest is a term used in certain Nordic technical contexts to describe a signal or procedure for testing the rendering and behavior of line graphics in digital media. It is not a widely standardized method and the precise meaning varies by discipline.

Etymology: the word is a combination of viiva, meaning line, in Finnish, and test.

In practice, viivistest appears in typography, charting, GIS, and user interface rendering as a lightweight check of line drawing under scaling, anti-aliasing, and coordinate transformations.

A typical viivistest includes a sequence of horizontal, vertical, and diagonal lines with varying widths, spacings, and colors designed to reveal misalignment, blur, clipping, or rounding errors in display or printing.

There is no formal standard for viivistest, and usage remains niche. References are largely in product manuals, academic notes, or blog posts from Nordic developers rather than official standards bodies.
