There really isn't any evidence of that. If it were true you'd see the
blending
into the pixels either side, but the pixels either side of the stem are 100%
white in both cases. And examining the subpixels inside the extremities of
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,
