Stria

Turn an image into different black-and-white patterns, like an engraving.

Stria converts an image into a black pattern on a white background, in four styles: parallel lines, regular dots, stochastic dots and cross-hatching. In each, the size or density of the elements conveys the brightness of the image: up close you see a pattern, from a distance the image reappears. Everything happens in the browser, nothing is sent to a server, and the result can be exported as SVG (ideal for printing or plotting) or as a high-resolution PNG.
