Informative Guide to Anti-Aliasing and Anisotropic Filtering

This is a pretty easy to read guide to what these two Video Card Features do and how they do what they do in layman terms that are easy to understand...they also include more technical explanations within the article for those geeks out there that understand such things.

I don't think they've removed the "hinting" button (properties panel). Clicking this button has had good results in many situations for me.

I ran into a related problem when I created my own View class for a custom JTextComponent. In the built-in View classes, antialiasing is applied via package-private methods of javax.swing.text.Utilities, which in turn call methods of the non-public SwingUtilities2 class. There is no way short of reflection hacks to tap into the automatic AA mechanism from a third-party View. And just to give the nipple an extra twist, they also moved SwingUtilities2 to a different package in JDK 1.6, making it all but impossible to achieve reasonably consistent behavior under both Java 5 and Java 6. I still can't help wondering if they implemented the AA mechanism the way they did just to piss me off.

Preview - anti aliasing and text in scanned pdf

hello all,
i have an issue with preview not anti aliasing text in pdf files. to elaborate, take a pdf with text which is selectable and it appears jagged, not anti aliased as in pdfs with text which is treated as an image, i.e. not selectable.
also, sometimes, when scrolling through pages in full screen, the following page has the text anti-aliased as the scroll animation is taking place, i.e. while the previous page is being moved away through the gesture, but once the previous page has disappeared and the new page 'settled in' the smoothing is gone.
smooth text and line art is checked, as is lcd smoothing in general preferences.
any suggestion are much appreciated.

Hi 1ndivisible,
Hmm, that's odd. My type is looking pretty decent out of Illustrator. Can you try a different font or the same font in a new sequence?
Thanks,

Hi Mosher
There are PCI/PXI solutions to do what you require. For example you could use an S-series device or a DSA board. However a set-up for connection to a laptop is more tricky. The reason is that devices with these features are based around generally high end and therefore need to use the higher bus speeds of PCI/PXI.
Is there definitely a requirement to use a laptop, or would a small PXI system or desktop be ok instead?

Web Filtering, Anti-Spyware and Email Filtering in one?

We have 4 Cisco ASA firewalls in place and currently use iMail and ISA server to filter web traffic and mail.
I'm investigating any solutions that would interoperate well with Cisco ASAs and provide a central solution for the above needs. Has anyone had experience of WebSense and Secure Computing, or indeed the newly acquired IronPort products?
Does anyone have any recommendations I can follow up?
Thank you,
Jason

IronPort is good stuff, but it is primarily for email. I have not used it's web stuff, but it is likely not as good as WW (for example, can it inspect SSL? Can it cache? Can it do "behavioral analysis").
Secure Computing WebWasher is good stuff. It is primarily for web. I have not used its smtp stuff, but it is likely not as good as Ironports;-)
I have no experience with WebSense, but it is also a leader in this space.
None provides a "central solution" in the sense that they can be managed in one interface along with the ASA's. They would inter-operate just fine with ASA's though. The ASA has a module for this too.

The images in Photoshop or InDesign improperly anti-aliased, looking fuzzy

I've bought Late 2013 Retina Macbook Pro with Mac OS Mavericks, and am having trouble with anti-aliasing.
In short, the images/documents open in Photoshop or InDesign are improperly anti-aliased and look fuzzy.
I can understand why the menu bars and stuff should appear fuzzy and blurry as a result of auto anti-aliasing; otherwise they might appear too small for eyes to see since the resolution is super high.
But why should the machine want to blow up the images or documents inside the application and apply anti-aliasing to make them look so fuzzy?
It would be grateful if there's a way to stop my computer doing the anti-aliasing all the stuff on screen.

No, not that I know of - you do need to make certain that you're using the very latest versions of both apps, though.

Why does scroll wheel temporarily kill anti-aliasing?

I have an odd display problem within inDesign. I have anti-aliasing turned on. When I use the hand tool or scroll bars to move around my document, the newly revealed area is drawn correctly and quickly. But when using my mouse scroll wheel to move around a document-- horizontal scroll especially-- the revealed parts of the document are not anti-aliased (and drop shadows are not drawn). I can switch to the text tool, edit my copy, switch to the cursor and move/change objects, whatever I want, but anti-aliasing does not re-activate. Then the instant I use the hand tool or drag a scroll bar, suddenly everything is redrawn correctly once again. I have tweaked my display performance sliders several times, but no matter what quality settings and options I use, I can see that the problem is still there.
Very annoying when I'm zoomed in looking at where I want a drop shadow to appear ... turn on its settings in the dialog box ... WHY WON'T IT GIVE ME MY SHADOW!? Oh, wait ... jiggle the page with the hand tool and suddenly it appears.
I am not getting an error message. Hardware acceleration is working in Photoshop. Downloaded the latest version of Logitech Setpoint software; that didn't stop it.
My system: InDesign CS4 ver. 6.0.4 on Windows Vista 64-bit; Logitech MX Revolution mouse; Dell 2209WAf monitor; ATI Radeon HD 4800 graphics card (already upgraded to more recent driver; didn't fix the issue).
I doubt it's the mouse itself; I use the same model at work (where we have CS2) and I've never had this happen there.
Help!
Ross Hight

Wish I could help but I am also experiencing the same problem. I just installed the newest video card drivers, however the problem still exists.
64-bit Vista SP2
CS 4
Quadro fx 3800
I have the same monitor as you and use a logitech mouse.
I didn't know about the jiggle trick though, helps a bit.
Thanks.

No anti-aliasing?

I have read that the Text Engine introduced with Flash Player 10 is supposed to provide anti-aliasing for devide fonts (i.e. non-embedded fonts). This is essential for Web applications: without anti-aliasing text looks awful and Flex applications cannot compete with HTML applications. But fonts that include East-Asian characters cannot be embedded because they take up too much space. And I don't see how a Web application in 2009 can fail to support East-Asian characters.
Today I tried Flash Builder 4, and created 3 Spark components, of types RichEditableText, RichText, and SimpleText, without embedding any fonts. All three could be rotated, which I believe means they use the new Text Engine. But none of them had anti-aliasing (which I checked by looking at how they rendered capital letter W). Why is this? Do I have to do something special to get anti-aliasing? Or is anti-aliaing a feature that will be coming later?
Thanks in advance,
Francisco

Hi Corey,
Thanks for your message. I've looked more carefully at the device font I'm using on the Mac (with an LCD display). You are right, it's anti-aliased. (I can't see any subpixel colorations with my magnifying glass as I can see them on Windows, but maybe they are just less obvious.)
So the reason the device font looks ugly on the Mac must just be the letter spacing. Since you said it looks good to you, I checked the code and did some experimentation. It turns out that I'm saying fontFamily="_sans" and, surprisingly, in Flex 3, this it not the same as not assigning a value to fontFamily. (Out of curiosity I checked Flex 4, and it is the same there.) Saying fontFamily="_sans" causes the letter spacing to be way off. If I don't say anything the spacing it still a bit off, but not too much, and the font does not look bad, although it still does not look as good as an embedded font.
I tried taking screen shots, but they come out a little blurry and it's hard to judge fonts on them. But I'm attaching a simple mxml file that compares the embedded font, the device font with no assignment to fontFamily, and the device font with fontFamily="_sans".
If you want to see the huge difference that fonts make on the application, the best thing is to look at the application itself, so I should say what it is. It's Noflail Search, a search engine that you can find at noflail.com. It starts out using an embedded font, but if it encounters an East-Asian character, or you specifiy an East-Asian language restriction, or you turn on an IME for an East-Asian language, it switches to fontFamily="_sans" (and lets you know that it does). To go back to the embedded font you can remove what caused the switch and reload the page. So it's easy to compare the effect of the two fonts.
The switching to the device font was my clumsy attempt at coping with the East-Asian character problem. Unfortunately the switching happens fairly often, because East-Asian characters pop-up in results when you least expect it, even if the query has nothing to do with East-Asia. So I will remove the "feature" soon, and just use device fonts and hope that most Windows users have ClearType enabled. But I'll leave it on all day Monday in case you want to check out the effect of the fonts on the application.
When I said that Adobe should not rely on embedded fonts I was referring to the fact that the nice anti-aliasing and text rendering that you have in Flex 3, and the presumably nicer one in Flex 4, is only available for embedded fonts.
Btw I've been comparing the subpixel anti-aliasing that I get with ClearType and a device font on Windows to the embedded font, and the embedded font looks definitely better. The device font with ClearType looks purplish, and the anti-aliasing does not seem as good. So let me emphasize that I'm not arguing that Adobe should use subpixel anti-aliasing. I'm arguing that the grey-scale anti-aliasing and text rendering that you use for embedded fonts should be used for device fonts as well. Is there any technical reason that makes this difficult? Impossible?
Thanks for listening

Certain Characters Aren't Anti-Aliased

This is a problem that I've had under Linux-based systems for a while, and I don't know if there's a remedy for it.
At around system font sizes (10-12), under both GNOME and Xfce, certain characters aren't anti-aliased (for example, Japanese characters) in certain programs (Firefox and Pidgin are the two main ones, but I recall there being others). I'm assuming that all of these characters are currently being used from other TTFs that I've installed, because DéjàVu doesn't seem to have them. At larger sizes in these programs, and at all sizes in LibreOffice, I don't seem to have this problem.
Is this a problem with GTK, these apps specifically, or my configuration? I currently have fonts for GNOME and Xfce set to greyscale anti-aliasing and full hinting, if that helps. What I want is for these characters to be anti-aliased, because it looks very odd when they're showing as monochrome against a bunch of anti-aliased letters. As far as I can tell, the hinting still works, however.

You most likely have the use of bitmap fonts or embedded bitmaps enabled somewhere in your /etc/fonts/conf.d. Once you find something like
<selectfont>
<acceptfont>
<pattern>
<patelt name="scalable"><bool>true</bool></patelt>
</pattern>
</acceptfont>
</selectfont>
or
<match target="font">
<edit name="embeddedbitmap" mode="assign">
<bool>true</bool>
</edit>
</match>
and change them to "false", you should be fine.

Anti-Aliased Fonts : FF2 vs IE7

I could have sworn Firefox was the first to come out with
font
anti-aliasing, for smoother text detail... then IE7 came out
and followed
suit, opening the door to fonts smaller than 10px looking
smooth (for
copyright notices and the like).
However, as I compare both browsers today, I see IE7 has the
anti-aliasing
but FF2 doesn't. Yet my FF2 install is defaults-only, so I
can't imagine I'd
have turned anti-aliased fonts off.
What happened? Did I imagine the whole thing, where FF came
out with
anti-aliased fonts first? Or did they try it and change their
minds in a
future update? Am I losing my mind?
Thanks.

I've printed both anti-aliased and non-anti-aliased fonts at
300dpi, and I
see a difference. In fact, there are several levels of
anti-aliasing, from
crisp to smooth.
Why are we even having this discussion? It's quickly turning
ugly.

It's being used as such on screens, yes. But it's not its
sole and only
purpose.

See above answer about being able to visually see the
difference between
anti-aliased and non-anti-aliased fonts at 300dpi.
What you can say is that YOU don't see it, but please don't

Please stop trolling me. :-P

Possible bug in Illustrator CS4 text anti-aliasing in Save for Web and Devices

Hello all,
This could be a bug... if so, I'd be happy to add it to Wade's bug list a few messages down the stream.
Here's what's happening: when I create small text using a very thin font (in this case, Helvetica Neue Light), the Pixel Preview gives a noticeably different anti-aliasing solution to the actual output from Save for Web & Devices. I'm attaching an original .AI file as well as a screenshots of what I'm getting in both situations.
I'd really prefer the Save for Web and Devices output to look exactly like the Pixel Preview. The font looks great in Illustrator but loses a lot of its punch when I Save for Web.
---Peter

In the Svae for Web and Device under the image tab where it says art Optimize that is a drop down menu select Type Optimize as such
htis is what it lloks like in AI and a browser when you choose Type Optimize
This the difference between Art Optimized and Type Optimize
That is what is happening to you you are selcting Art Optimize and that is the reason when you choose art optimize aqnd you rraster the image it looks right to you.

[SOLVED] How to turn on font hinting and font anti-aliasing?

I wanted to configure hinting and anti-aliasing, although I've never used fontconfig before.
I had been reading https://wiki.archlinux.org/index.php/font_configuration and I have found some contradictions.
First it says "Configuration can be done globally through /etc/fonts/fonts.conf" and then immidiatelly after that it says "This file is replaced during fontconfig updates and shouldn't be edited".
Then it says per-user path ~/.fonts.conf is deprecated in turn for $XDG_CONFIG_HOME/fontconfig/fonts.conf with no indication where should this "$XDG_CONFIG_HOME" actually be.
I get that I am supposed to put my custom XML "somewhere":
<match target="font">
<edit name="hinting" mode="assign"><bool>true</bool></edit>
<edit name="hintstyle" mode="assign"><const>hintfull</const></edit>
<edit name="antialias" mode="assign"><bool>true</bool></edit>
</match>
But I have no idea where?
Last edited by choosegoose (2015-02-02 23:22:56)

Normally the $XDG_CONFIG_HOME variable points to .config in your /home/<user> directory.
So the path that you would use would be: /home/<user>/.config/fontconfig
Please note that it's DOT config.

Bitmap smart objects and anti aliasing, Photoshop CC

Photoshop CC is doing a poor job of rendering bitmap smart objects, and I saw Chris Cox mention the checkbox to enable anti aliasing for placed smart objects. This works with vector smart objects, but this box is grayed out for bitmaps that I've converted to smart objects. The smart object bitmap renders poorly when manually rasterized too. I don't recall having this problem in previous versions of Photoshop. For now I'm going to avoid converting bitmap elements to smart objects so I get decent transforms.

There are no jagged lines in that example - you're just rasterizing at a REALLY low resolution.

[SOLVED] FontConfig Update and Anti-Aliasing

After doing upgrade of fontconfig exactly like explained on news here;
http://www.archlinux.org/news/fontconfi … -required/
Font became too thin, I think anti-aliasing is working wrong now. I've even added this:
https://wiki.archlinux.org/index.php/Fo … igurations
Also, my appearance settings is:
Default Font: Sans / Size: 10
Rendering: Enabled anti-aliasing
Hinting: Full
Sub-pixel order: None
DPI: Custom DPI setting 96
Here is few examples:

Is there anyhting else I can do to fix this ?
Last edited by TuxLyn (2012-09-08 04:41:23)

My fonts were also looking bad after the upgrade (the same as in your screenshots), what I did:
mv .fontconfig .config/fontconfig
mv .fonts.conf .config/fontconfig/fonts.conf
mkdir .config/fontconfig/conf.d
ln -s /etc/fonts/conf.avail/10-sub-pixel-rgb.conf .config/fontconfig/conf.d ## Though this wasn't really necessary.
Moved all cache files from .config/fontconfig (formerly ~/.fontconfig) to ~/.cache, as suggested in the wiki.
And I copied this in my fonts.conf (.config/fontconfig/fonts.conf), examples you can also find in the wiki:
<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
<match target="font" >
<edit mode="assign" name="autohint"> <bool>true</bool></edit>
<edit mode="assign" name="hinting"> <bool>false</bool></edit>
<edit mode="assign" name="lcdfilter"> <const>lcddefault</const></edit>
<edit mode="assign" name="hintstyle"> <const>hintslight</const></edit>
<edit mode="assign" name="antialias"> <bool>true</bool></edit>
<edit mode="assign" name="rgba"> <const>rgb</const></edit>

<edit mode="assign" name="hintstyle"><const>hintnone</const></edit>
<edit mode="assign" name="lcdfilter"><const>lcdlight</const></edit>

<edit mode="assign" name="hintstyle"><const>hintnone</const></edit>

<edit name="hinting" mode="assign"><bool>true</bool></edit>
<edit name="hintstyle" mode="assign"><const>hintfull</const></edit>
<edit name="lcdfilter" mode="assign"><const>lcddefault</const></edit>
<edit name="rgba" mode="assign"><const>rgb</const></edit>
</match>
</fontconfig>
Now my fonts look like before, and Chromium looks even better, thanks to one of the examples found.

Java font kerning and anti-aliasing

Hi,
I have to create images containing text with font kerning and anti-aliasing.
Also (although I don't think it makes much difference):
- I am using a special font, not a system font (Helvetica Neue Condensed).
- I intend to run this on Linux
The images will be saved as GIFs. This is something that i know very well.
If you have any comments regarding at least one of my problems (1. kerning, 2. anti-aliasing) please let me know.
Thank you very much.
All the berst,
Andrei

The J2SE (Java 2D) doesn't provide much support for these. You can set the following
hints on your Graphic2D object before rendering text:
g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
g2.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS, RenderingHints.VALUE_FRACTIONALMETRICS_ON);I find these hints work best with large fonts (say >36 pixels height!) and sometimes fractional
metrics looks better on, sometimes better off (sometimes either way looks bad!).
Fractional metrics is different from kerning, but sems to be the closest you can get to it in the J2SE.
I don't know if JAI has anything like it, but I have read some mention of kerning in Batik.
