Educative blog for our OpenJDK community folks!

Technology and fun

Recently I’ve spent a lot of time investigating font rasterization (a great topic which deserves a separate post). Most applications use font engine which is built into graphics library or widget toolkit. Only few cross-platform applications which badly need to provide consistent text layout (Acrobat Reader, for example) are using their own font engines (like Adobe CoolType). Java platform is one of such applications, since it has its own graphics library. If you are curious take a look at this article comparing font engines, including one from Java platform.

But I could not find any traces of freetype.dll in JDK. I was puzzled and tried to find some answers in sources of OpenJDK. Imagine my surprize then I’ve found…
