I am not sure what you are looking at but I see 255,255,255 pixels on
all sides of
the stems. The stems are touching 3 pixels. I'm talking about the ones
to the sides of
those 3 pixel wide stems.
In any case I've used Windows 7 wordpad and Segoe UI 9pt (aka 12pixel) and
can see identical rendering to your Outlook case.
Wordpad (and so I infer Outlook) is using GDI which
1) is very likely a different rasteriser (FX is using the one from
DirectWrite)
2) doesn't do sub-pixel positioning because its only got int APIs.
So this seems to come down to DirectWrite vs GDI and personal
preferences ...

That's not true. There is a difference in the "white" space around
the letters. The "white" pixel before the stem of the L is not 100%
white in either case and the difference is in line with what I would
expect if there was a sub-pixel shift..

There really isn't any evidence of that. If it were true you'd see

the stem backs me up ...

I think the stem of the L is colored differently because of
*sub-pixel* differences in its position. I.e. it appears to
be at the same integer position, but it isn't at the same real
position. It looks to me like that alone could account for
the differences.

You only need to look at the first letter "L". The stem is in
exactly the same place isn't it? And yet the colours are
different.
The overall length is different which I attribute to rounding
differences
or metrics differences used in accumulating the position
but that
is a guess.

If you notice, in the images provided, the length of the
rendered text in pixels is significantly different
between the
two examples. That supports the theory that it is simply,
sub-optimal positioning of the glyphs that is
resulting in the
more pronounced LCD anti-aliasing.

Perhaps the gamma adjustment is different ?
FX should pick this up from the
SystemParameterInfo SPI_GETFONTSMOOTHINGCONTRAST
setting.
I don't know what Outlook (*) uses if its a WPF
app then
maybe its
picking
up an over-ridden setting for this from the registry :
http://msdn.microsoft.com/en-us/library/aa970267%28v=vs.110%29.aspx#gamma_level
You should be able to check that out fairly
easily,and you
can use
this
JDK app to see what the SystemParameterInfo
setting is.
import java.awt.*;
import java.util.*;
public class GetGamma {
public static void main(String args[]) {
Toolkit tk = Toolkit.getDefaultToolkit();
Map map =
(Map)tk.getDesktopProperty("awt.font.desktophints");
if (map != null) {
for (Object k : map.keySet()) {
System.out.println(k + " : " +
map.get(k));
}
}
}
}
C:\>c:\jdk1.8\bin\java GetGamma
Text-specific antialiasing enable key : LCD HRGB
antialiasing text
mode
Text-specific LCD contrast key : 120
(*) I'm sure Outlook used to be a GDI app, but who
knows what
version you are using
and what rendering technology it uses.
I've tried to make the point many times before that
someone can
always point to
a difference from 'native' rendering simply
because the
platforms
like OS X and Windows
have multiple rasterisers and multiple font
technologies
all of
which are different
from each other. So whilst any notably 'poor'
rendering
needs to
be looked into
it maybe sometimes an artifact of one rendering path
compared to
another ..

Hi all,
I think there is still room for improvement in
terms
of the
'contrast' or 'vibrancy' of fonts in JavaFX.
Take a
look at
this example:
http://i.imgur.com/6qSamTO.png
I'm running Windows 7. What you are seeing is a
screenshot of
the default font, zoomed in 600%. The top text
is JavaFX 8
(latest build as of 3 days ago). The bottom
text is
Outlook
but could just as easily have been Firefox,
Chrome,
Word, or
Eclipse SWT - they're all indistinguishable to me.
The JavaFX text doesn't look as vibrant. In
particular the
smoothing algorithm seems to be making poor colour
choices for
the vertical strokes. At 100% the difference
is subtle but
important.
I have the text fill set to Color.BLACK and
the font
smoothing
type set to LCD. Is there something else I can
configure to
get more vibrant-looking fonts?
Cheers!
Rob

Betreff: Re: Poor font rendering..
Hi Pedro,
Font rendering in FX8 is using the native
rasterizer
so the
glyphs should be identical to what the
operating system is
rendering. That said, we may have a bug.
Please enter
a JIRA
with sample code and a screen shot of the bad
rendering. That
will give us something concrete to work with.
Thanks,
Steve

Hi,
As evidenced by the screenshots in
http://pixelduke.wordpress.com/
blog posts about JMetro, javafx as
noticeably poor
font
rendering
visuals. The most recent screenshots were
taken on a
windows 8.1
machine and the older ones on windows 7, using
Segoe UI
(windows 7 & 8 system font).
1- As this been reported?
2- Is the javafx team working on it?
3- Is there something the developer can do
to increase
font rendering
quality?
Thanks!
Best regards,
