Font rasterization is the process of converting text from a vector description (as found in scalable fonts such as TrueType fonts) to a raster or bitmap description. This often involves some anti-aliasing on screen text to make it smoother and easier to read. It may also involve hinting—information embedded in the font data that optimizes rendering details for particular character sizes.

Especially for small font sizes, rendering of vectorized fonts in "thumbnail" view can vary significantly with thumbnail size. Here, a small change in the upright= multiplier from 1.70 to 1.75 results in significant and mutually distinct rendering anomalies, possibly due to rounding errors resulting from use of integer font sizes.[original research?]
