small sizes. Sub-pixel rendering The program supports sub-pixel rendering to optimize image quality for LCD displays. Although RGB vertical striped arrays are common, Saffron can also render to alternative pixel patterns such as RGB delta arrays, which are often used on digital camera LCDs. In addition, prototype implementations of Saffron are optimized for Clairvoyante's PenTile patterns. During sub-pixel rendering, the program reduces color fringing artifacts that would otherwise be visible at small sizes. Continuous stroke modulation Saffron exploits the inherent properties of distance fields to provide continuous stroke modulation (CSM), the continuous modulation of both stroke weight and edge sharpness. This allows users to tune the appearance of text to suit individual preference. For example, sharper, softer, thinner, and thicker versions of the same typeface can be rendered by using different CSM parameters.
