It was very deliberate that advances from the JDK's rasteriser was used
because many
applications were very sensitive to metrics. This was back in the T2K
days and it just
carried over to freetype. It worked out just fine with T2K but not so
much with freetype
I don't think I want to just take a patch which switches to GDI either,
so I wouldn't
bother preparing one. I need to take a big look at the whole picture
when I get time.

<div>That's true. On Windows, LCD-antialiased glyphs are
generated via GDI, but glyph advances are taken from
FreeType. Rendering in newer FreeType seems to differ more
from GDI rendering, so the result started looking worse.
We've fixed this problem in JetBrains Runtime by keeping
GDI-provided advances (for non-fractional-metrics case).
If it's a sensible approach (I'm not sure I understand why
advances from FreeType were used in the first place), I
can prepare corresponding patch for inclusion in OpenJDK.<br>

<div>From what I

Any OpenJDK

using Freetype

<div>I have only tested on Windows
10 Home 1803, with no font
scaling enabled. My initial
tests were performed using a
desktop application, many
OpenJDK distributions, and
visually comparing the poor
kerning when using Tahoma.</div>
<div><br>
</div>
<div>I have now produced a
screenshot using sample text and
12 different OpenJDK
distributions. I have
highlighted the font kerning
issues in a zoomed/cropped
image:</div>

<div><br>
</div>
<div>Each window in the above
screenshot represents a
different OpenJDK distribution
running on my Windows
environment with or without the
FREETYPE_PROPERTIES environment
variable specified:</div>
<div>
<ul>
<li>the sample text is
"Activity dwedwedwedwe"
though kerning issues can be
seen throughout most text
within the dialog</li>
<li>the first JLabels use the
default font, while the last
three JLabels use 10pt,
11pt, and 12pt Tahoma</li>
<li>the left-side windows do
not have FREETYPE_PROPERTIES
specified</li>
<li>the right-side windows
have FREETYPE_PROPERTIES
specified<br>
</li>
<li>the first 8 OpenJDK
distributions all show
kerning issues which are
fixed by setting
FREETYPE_PROPERTIES</li>
<li>the last 4 OpenJDK

kerning issues at all and
are not affected by
setting FREETYPE_PROPERTIES</li>
</ul>
</div>
<div>
<div>As shown in the screenshot,
setting the
FREETYPE_PROPERTIES
environment variable appears
to fix the kinds of kerning
issues described in
JDK-8217731 and JDK-8214538. I
have not checked if it fixes
the line spacing issue
described in JDK-8217731, but

<div> Note that
AdoptOpenJDK's
distribution
for Java 8
didn't require
the workaround
because it
appears to be
using Freetype
2.5.3. A quick
Google for
\
"truetype:interpreter-version=35" shows plenty
of people in
other
open-source
communities
(eg. Wine,
Fedora) which
encourage this
workaround for
other
software.</div>
<div><br>
</div>
<div>A more
permanent
solution would
be to change
the default
build process
for OpenJDK to
set
\
"truetype:interpreter-version=35" as the default
when compiling
Freetype.</div>
</div>
</div>
</div>

<br>
I have read freetype
notes on this and it
isn't clear whether we
want to go against what
it does by default.<br>
And in any case, Oracle
JDK switched from T2K to
freetype in 11 so there
can be differences due
to that too.<br>
<br>
It may be that Windows
is the only platform on
which this reversion is
a good idea.<br>
And in any case, on
Linux + Solaris (not
sure about other
Unix-like distros)
OpenJDK<br>
currently uses the
system freetype so a JDK
build change for
freetype wouldn't help.<br>
</div>

<div><br>
</div>
<div>After reading a little more,
I would suggest keeping the
latest Freetype but compiling it
using truetype:interpreter-version=35 to fix the kerning issues.</div>
