Popular Applications
- In computer-aided design (CAD) drawings (blueprints etc.) are scanned, vectorized and written as CAD files in a process called paper-to-CAD conversion or drawing conversion.
- In geographic information systems (GIS) satellite or aerial images are vectorized to create maps.
- In graphic design and photography, graphics can be vectorized for easier usage and resizing.
Unlike the opposite process rasterization, vectorization is not well defined, meaning there is not a single correct method. Many different algorithms exist, and each gives different results, as vector representations are more abstract than pixels.

Famous quotes containing the word popular:
“You seem to think that I am adapted to nothing but the sugar-plums of intellect and had better not try to digest anything stronger.... a writer of popular sketches in magazines; a lecturer before Lyceums and College societies; a dabbler in metaphysics, poetry, and art, than which I would rather die, for if it has come to that, alas! verily, as you say, mediocrity has fallen on the name of Adams.”
—Henry Brooks Adams (1838–1918)
