Hi,
Yep, Phil is the one who designed font management code.
I can't wait for Phil to come back and have a look at our redesign of
the FontManager related code :-) (Maybe it's not so bad that I am in
holiday then .. ;-) ). But this one here is not so much about
FontManager but more about the low level Freetype loading stuff. (I
thought that code was from you Igor? I might be wrong though).
Yes, freetype glue code was written by me.
But fo IO i've used same approach as we use for t2k and this approach
was introduced on purpose in jdk 1.5.
Anyway, i promise i'll look into this in more detail as i get some spare
time (that is really rare these days :()
From the top of the head i'd sugegst to check impact of such change on
performance and perceived
footprint scanning large set of large fonts.
I can do that. Any suggestions on how to do that easily? I'm not sure
how that (FreeType) implementation works, but I know at least one font
implementation that doesn't actually load anything until the
corresponding glyphs are needed (also mmap-based, very handy... this is
the code in Classpath, all Java, all nice :-D ).
Both freetype and t2k do not read everything explicitly too.
However, to build list of all available fonts we have to scan some
tables in all files.
And it will be unfortunate if process size will grew by total size of
all fonts.
Quick tests are: run Font2DTest on system that has some really large
ttf/ttc files.
Write simple test that iterates through all available fonts and draw one
or all glyphs to bufferedimage.
I likely be mistaken here
but on some platforms
(Windows) this might have noticeable negative consequences.
Unfortunately, I don't have a Windows box around, and can't setup one
easily. Windows licenses and VS licenses are too costly for my taste.
Also, at work, some people tried to setup a build of OpenJDK on Windows
and failed (or at least, did not succeed after 16 hours of work or so).
It will be nice to hear why it does not build on Windows.
I am quite sure OpenJDK is buildable with commercial VS and
i know that some people were building it with VS Express too (with minor
tweaks).
