Hi there,
I have a problem related to fonts. As you might know, I'm hacking on the
OpenJDK challenge thing and try to implement an external toolkit/J2D
pipeline based on external and internal interfaces etc. Progress is
pretty good so far, as can be seen here:
http://kennke.org/blog/2008/04/16/caciocavallo-prototype/
Is the text on that "Swing Activity Board" what we are supposed to be
looking at?
However, there seems to be a problem related to fonts. To me, it looks
like they are not hinted properly. My TextRenderer implementation is
very simple and straightforward:
The only control for font hinting is how the rasteriser - freetype - is
compiled.
If your copy of libfreetype is built with hinting turned off, then that
will make a difference.
The usual compensation for that is antialiasing the text.
Still that looks pretty grotty, maybe there's something more to it, like
a font that
wasn't very amenable to auto-hinting, although it looks like a fairly
straightforward sans font,
I notice the text in the window manager title bar that presumably comes
from your desktop
may be the same font and its greyscale and looks like it would also be
grotty in B&W.

But I guess it is not really the problem, because the pixels are already
arriving badly there.
Is there another point that controls this behaviour? Something in
FontConfiguration or FontManager maybe? (BTW: I re-engineered the
FontManager stuff - and other - quite a bit, but if you point me to a
place in the current OpenJDK version, I could map it to mine).
For completeness, the code to the toolkit is here:

You'd also need Escher:

and our patches to the OpenJDK tree:
