[[File:20200522 SVG font rendering at different thumbnail sizes.gif|thumb|right| upright=1.8| Especially for small font sizes, rendering of  vectorized fonts in "thumbnail" view can vary significantly with thumbnail size. Here, a small change in the <code>upright=</code> multiplier from <code>1.70</code> to <code>1.75</code> results in significant and mutually distinct rendering anomalies, possibly due to rounding errors resulting from use of integer font sizes.{{original research inline|reason=Not a good idea to put a librsvg-c bug with dubious cause here as an article image.|date=March 2023}}]]
'''Font rasterization'''  is the process of converting text from a [[vector graphics|vector]] description (as found in scalable fonts such as [[TrueType font]]s) to a [[raster graphics|raster]] or [[bitmap]] description.  This often involves some [[spatial anti-aliasing|anti-aliasing]] on screen text to make it smoother and easier to read.  It may also involve [[font hinting|hinting]]—information embedded in the font data that optimizes rendering details for particular character sizes.
