As for LCD on Canvas, I am very pleased that it is being addressed and even
though I want it right now, JFX 9 fits fairly well with my timeline. Hopefully
there will be preview releases to test in the not too distant future...
Btw, as I mentioned in another thread we are looking to pull
LCD-on-Canvas into an 8-update release (possibly 8u40).

Hi Felipe,
Thanks for your prompt and informative response.
I won't be able to get access to a Windows machine for another week or so but
when I do I will gladly send you some screenshots. However, are you saying
that this is the first time anyone has reported such a finding? There's no
existing JIRA for this specific issue? I ask because even though people tell me
I am super fussy with fonts and see things others just can't see, I have
observed the stated discrepancy on *every* Windows machine I have tried with
JFX 8 (about 4 quite different machines) so I would be very surprised if no one
else notices a difference.
Thanks for the J1 suggestion but sadly I will not be able to attend this year.

Hi John,
1)
There are many different ways to configure DirectWrite, but without more
details I can not tell what that is for your case.
Maybe the first thing to try is to go to DWGlyph#createAnalysis() and changed
the rendering mode from DWRITE_RENDERING_MODE_NATURAL to
DWRITE_RENDERING_MODE_GDI_CLASSIC or DWRITE_RENDERING_MODE_GDI_NATURAL. That
said, there are many other knobs to try and combine.
You can also file a jira with images of your javaFX application and a native
app using the very same font and size, same foreground, and same background.
That should enable me to try it on my machine too.
In case you are coming to JavaOne this year, you could bring your laptop and
application, I have a BOF on text rendering scheduled. We could hack some code
together and maybe find a solution.
2)
LCD text rendering on Canvas is assigned to Jim, see
https://javafx-jira.kenai.com/browse/RT-23822
The fix version recored on jira is 9, it would be nice if we could get it
before that but I don’t know if it is possible, Jim ?
Thank you,
Felipe

Hi Felipe,
I just finished watching your excellent presentation at SVJUGFX on text
rendering with JavaFX and have a couple of multi part questions:
1) I noted that DirectWrite is now used to rasterise fonts on Windows instead of T2K or GDI and I
for one am pleased about this. However, no matter what I do I just can't get JavaFX text to be
rendered as crisply or as "black" as I see in native Windows apps that also use
DirectWrite. The result is that my app undesirably "stands out" from a native app.
What could be the cause of this? I saw that DirectWrite provides several
options for rendering text and that currently only the default one is being
applied so could it have something to do with this?
Is work being done to reduce the differential between JavaFX text rendering
quality and that of native Windows apps?
2) I appreciated the explanation relating to LCD text in Canvas and the issue
with the Canvas initially bring a transparent surface making later blending
with an actual background problematic leading to greyscale support only.
Given that many of us see this as a very serious impediment to developing
complex controls that use Canvas, is there a focus within the JFX team on
finding a way of supporting LCD text in Canvas and if so, which JFX version is
likely to first include this support?
Thanks again for a great talk and for all the hard work you have put into
improving text rendering in JavaFX :-)
