Question: What is a rasterizer? Why doesn't Java 2D use a native rasterizer for rendering fonts?

Answer: A rasterizer takes ideal shapes and produces coverage values for each pixel. The coverage values represent how much of each pixel is covered by the shape. These coverage values are called alpha values. Each pixel has its own alpha value which indicates the transparency of the pixel.

The Java 2D API uses the T2K font rasterizer from Type Solutions. The Font Fusion font engine is independent of processor and OS and compatible with all industry standard font formats. It is a full featured lean, mean and fast next generation small-footprint multilingual scaleable outline font technology. Font Fusion was designed for both gray-scale and black and white, ROM and non-ROM, based devices where the fonts may reside locally or remotely.

By allowing T2K to rasterize fonts, the Java 2D API isn't dependent on native rasterizers for the scalable outline fonts that it supports, which results in more consistent metrics display across different platforms and between on-screen and off-screen rendering.
