[Freetype] point coordinates of glyphs

[Angela Hunziker]

Hello

I'm trying to code the Rendering of TrueType fonts in java.
The point coordinates of some glyphs I read out from the font file are
pretty weird. When I try to connect these points to get the outline of a
glyph, it doesn't look very nice. Could it be that the point coordinates in
the font file produce a weird glyph? Does the hinting of glyphs maybe
correct these errors of the outline?
I already coded the loading of all the tables and the producing of the
bitmap but I left out the instructing of the glyphs. That's why I'm not sure
if I'm reading out the point coordinates correctly or if the glyphs look
weird because they haven't been instructed yet.
Actually, I don't think that the reading out of the outline points is wrong
because some of the glyphs look correct and only part of them look strange.
Two examples in the simple 1-0 format, which haven't been instructed yet:

the capital 'F': (which looks ok)

the capital 'G': (which doesn't look ok)

Could it really be that the capital 'G' above, which hasn't been instructed
yet, does look like a capital 'G' after instructing or is the error to be
found elsewhere (e.g. in the loading)?
