I get these days these two warnings:
Code:

Apparently the digests are wrong.

Hi there. Anyone can put in first post, or post here info how start with new font rendering?

Just add "fontconfig -cleartype ubuntu" use flags, remerge what need it, remerge for example firefox and should work? IIRC I have been using it a long time ago and there was need to use eselect fontconfig but now I see sub-pixel conf's there.

Code:
# eselect fontconfig list
Available fontconfig .conf files (* is enabled):
  [1]   10-autohint.conf

Also, @bi3l why you using tar to publish your overlay? I think a way better would be put it in git, at github for example and it will make super easy to merge your overlay into another.

Temporarily, I deleted devnull and used the tar from here: http://ogmrip.sourceforge.net/misc/gentoo-lcd-filtering.tar.bz2 The ebuilds from the tar seem to work fine if you copy them to your local overlay.

You should definitely play with eselect fontconfig to find your favorite settings.

There is no good answer to that question, except because I'm a bit lazy. I'll switch to github or gitorious one day or another.

Only for me small fonts with 'ubuntu' useflag are very hard to read?

Anyway, if anyone interesed, I merged gentoo-lcd-filtering.tar.bz2 latest to http://github.com/slashbeast/foo-overlay and will keep it updated.

So? Read this thread. You can change how they are rendered. E.g.:
Code:
   <!-- Greyscale for small fonts -->
   <match target="font">
      <test name="pixelsize" compare="less_eq"><double>7</double></test>
      <edit name="rgba"><const>none</const></edit>
   </match>


Here's my ~/.fonts.conf for Infinality's rendering, which is the best rendering - but, use Infinality's own configuration, since he does a better job than me.

For posterity, here's my old ~/.fonts.conf for Ubuntu's rendering.

Edit: Updated my ~/.fonts.conf for Postscript substitutions.
Edit2: Updated for better rendering of small italics.
Edit3: Better rendering of Arial Bold.
Edit4: Many miscellaneous tweaks, for individual fonts, and generalities such as small bold.
Edit5: Stopped replacing Helvetica 11pt with Arial - it's not needed anymore, and such replacing is nasty.
Edit6: Reorganized rules, stopped using "append_replace" (seems to have bad side-effect of also replacing other fonts in the same "family), and further tweaked the hinting rules.
Edit7: Tweaked Luxi Sans bold. Now using <match target="font"> instead of the seemingly-weird <match name="family" target="pattern">
Edit8: Tweaked Arial Black.
Edit9: Made Microsoft fonts hintfull.
Edit10: Tweaked Verdana bold.
Edit11: Tweaked Baskerville font.
Edit12: Am partially replacing Arial with Calibri, because Arial looks so bad.
Edit13: Tweaked Arial Black bold with hintnone.
Edit14: Split the horrible Arial into Calibri (small) and Corbel (small bold). Enabled embeddedbitmap for small sizes.
Edit15: Tweaked smallish Arial Bold to use hintnone instead of hintslight.
Edit17: Disabled "embeddedbitmap" - it's pointless for our purposes of getting nice anti-aliasing.
Edit18: Using CartoGothic Std and PT Sans (both free fonts) to replace Arial small-ish.
Edit19: Tweaked PT Sans bold and not-so-small.
Edit20: Tweaked Aller, Lucida Grande bold, and Luxi Sans bold & small.
Edit21: Minor tweaks to some free fonts: Aller, Droid, Fontin.
Edit22: Switched to Infinality's superior rendering, which makes the Ubuntu-specific tweaking obsolete.

The devnull overlay has removed cairo-respect-fontconfig.patch in cairo-1.8.8.ebuild, which is a mistake.

The patch is needed, so as not to partially ignore the fontconfig files in /etc/fonts/conf.d/ and ~/.fonts.conf

Can you put it back in please? Why was it taken out?

Edit: I've finally reported this patch upstream.

Fixed both in devnull and lcd-filtering. I can't remember why it was taken out but I'm pretty sure there is no good reason.

Edit. BTW, I've switched lcd-filtering to gitorious. See my signature.

The more I read this thread, the less I understand any of it. I've tried installing from the overlays mentionned in this thread but I couldn't see any difference in KDE. Could anyone be kind enough to take a couple of screenshot both with antialiasing and full hinting, one with the default Gentoo stuff (with the cleartype use flag) and another with any of devnull/lcd-filtering/callisto overlays (as it seems they all share the same patches?) to highlight the difference between the two? That would be really great, thanks!

i'm a little confused. so does this mean we don't need the cairo overlay anymore? also, is the portage cairo lcdfilter flag the same as the ubuntu flag from the overlay cairo?

I've been tweaking my ~/.fonts.conf a lot recently, and here it is - any decent feedback? :)

I'm especially interested in fontconfig ruleset tweaks, if anyone has them, for fonts that I've ignored, or where they greatly disagree with my choice (then we'll get into the complexities of e.g. DPI, screen resolutions, font versions, etc.).

Some useful miscellaneous debugging commands:

fc-match --sort "Symbol"
fc-match -a | uniq | sort | less
fc-match -a | grep -i n019003l
fc-list "Nimbus Sans L"
fc-cat ~/.fonts/ | grep Condensed | cut -c-78
fc-query ~/.fonts/n019003l.pfb
lsof | grep -i firefox | egrep -i 'ttf|pfb'

I was testing your config earlier, some fonts are still too fat. Example: the font of the name of the blog isn't fat, that's good, but the headline is. I'm running Windows and configuring my fonts in Linux in VirtualBox, so I can compare easily.

The headline ("Good teachers help students...") is Tahoma (bold): tahomabd.ttf

Code:
$ fc-query ~/.fonts/tahomabd.ttf | grep -i weight
   weight: 200(i)(s)


200 is bold. But anyway, you're right. I've added a rule to make Microsoft's fonts hintfull. Try it now :)

My bad. I later found out it was tahoma and I didn't have that installed.

I've been testing a lot of different stuff lately, using your conf as a guide. Not that I mind, but issuing the kill command over and over again (kill, kill, kill, kill, kill, kill...) makes me a bit uneasy.

I like your conf, and it pretty much renders stuff correctly as far as I can tell, but it does make everything look too thin. Perhaps preferential, but I do like my fonts to look slightly fuzzy. (Rather too fuzzy than too thin.) I'm using my own fonts.conf right now, using anti-alias, rgb, hintslight, and hintnone for Arial specifically. Testing this stuff out isn't the easiest thing to do. Is there a website that displays fonts that are used very often in their oft-used sizes? That would make comparing fonts between Windows and Linux so much easier.

Too fat or too thin, based on whether we use hintmedium or hintfull :cry: Maybe we need hintabitmorebutnottoomuch :P

Well, state specific examples, so I can look at tweaking them. Within the confines of what fontconfig provides, obviously.

Arial is the font that I hate the most - it won't look great when small, no matter what options are chosen. Most of my font-specific tweaking is for Arial small/bold, at e.g. digg. I think I might even replace it (with Calibra? Liberation Sans?).

It will be easy to create a test HTML page (example), and I'll do this soon. Also, typetester may be useful.

Here's a Python program to generate HTML of various fonts, and its outputted HTML page - save it, then open it in e.g. firefox.

Of course, your web browser relies on the fonts you have installed (and its settings, e.g. minimum font size) - the fc-query and fc-match commands will help to explain what you see.

PostPosted: Fri Apr 30, 2010 3:09 am    Post subject: Xorg driver Reply with quote

A lot of this also depends on the Xorg driver being used. I've tested nouveau and nvidia, the former has absolutely no anti-aliasing, the latter does have some form of anti-aliasing in nvidia-settings. Though I am not sure how and to what decides applying it. I like microfonts (really tiny) and the Nouveau driver made them blurry and had some sort of glitch where in terminals bold r's would stick out like an overgrown wart full of hair.

Using 'nvidia-settings' I have anti-aliasing at max and now changed to 'Use Application Settings', it was set to 'Override Applications Settings'.

so ppl, please bear this in mind when making accusations about fonts!! radeonhd, fglrx, nvidia, nouveau, vesa, your screen resolution etc, there isn't a silver bullet to fix ALL fonts in ALL systems.

Also another thing I've noticed is that some settings only take effect after re-starting X. For instance testing terminal fonts xrdb -load .Xdefaults just changes the font but not the hinting and anti-aliasing settings that are either in .Xdefaults or .fonts.conf file.

Having said that, I am using for my terminal Inconsolata font and firefox uses the following:
Code:
lsof | grep -i firefox | egrep -i 'ttf|pfb'                                                                                                     
/usr/share/fonts/umeplus-fonts/umeplus-p-gothic.ttf                           
/usr/share/fonts/dejavu/DejaVuSerif.ttf                                       
/usr/share/fonts/dejavu/DejaVuSans.ttf                                         
/usr/share/fonts/corefonts/verdanaz.ttf                                       
/usr/share/fonts/corefonts/verdanai.ttf                                       
/usr/share/fonts/dejavu/DejaVuSansMono-Bold.ttf                               
/usr/share/fonts/corefonts/trebucbd.ttf                                       
/usr/share/fonts/corefonts/verdana.ttf                                         
/usr/share/fonts/corefonts/verdanab.ttf


So far letting default stuff on without changes everything looks better than all those custom .fonts.conf that've tried.

cheers!!

Hang on a minute, aren't you talking complete nonsense?

nvidia-settings is for opengl anti-aliasing - this thread is talking about 2D apps like Abiword, Openoffice, geany, etc. What apps are you using, in which nvidia-settings' anti-aliasing affects text rendering?

Quote:

Wrong. You just need to restart the app (maybe you had multiple xterms open, and need to close every instance?). This is easily proved in e.g. qtconfig:

Code:
(Set e.g. Xft.dpi: 120 in ~/.Xresources)
xrdb -merge ~/.Xresources
qtconfig
(See fonts change size)

Quote:

That is most certainly absolute nonsense. Try the sample font HTML I provided above, and experiment with your settings, and you'll see that some fonts need e.g. hintslight/hintfull to prevent looking ugly or too bold, whereas other fonts may need e.g. autohint (a good example is Luxi Sans at Market Ticker, which looks ridiculously mis-shapen with hintmedium instead of hintslight). Look at my ~/.fonts.conf above, and you'll see the tweaks that I've found that can be used to improve the look of the fonts.

In other news, I've updated my ~/.fonts.conf above to replace Arial *sometimes*, because it looks so poor when small/bold and cannot be fixed, and it's so ubiquitous that I cannot tolerate its ugliness, when other fonts manage to look decent at the same size :)

oops, you are right I got confused then. I assumed anti-aliasing always referred to fonts LAWL!! Didn't think linux actually HAD 3D games needing anti-aliasing and associated games and anti-aliasing with m$$ games.

Also that didn't change a thing.

Code:
(Set e.g. Xft.dpi: 120 in ~/.Xresources)
xrdb -merge ~/.Xresources
qtconfig
(See fonts change size)


I have two 23" with a res 2048x1152 apiece.

Code:
[    80.986] (II) NVIDIA(0): Computing DPI using physical size from Samsung SyncMaster
[    80.986] (II) NVIDIA(0):     (DFP-0)'s EDID and first mode to be programmed on Samsung
[    80.986] (II) NVIDIA(0):     SyncMaster (DFP-0):
[    80.986] (II) NVIDIA(0):   width  : 2048 pixels  510  mm (DPI: 101)
[    80.986] (II) NVIDIA(0):   height : 1152 pixels  290  mm (DPI: 100)


From my /var/log/Xorg.0.log. Is this the same dpi as Xft.dpi: in .Xresources/.Xdefaults? I am confused about this. Concerning fonts there are a few places where to set them in .Xresources/.Xdefaults:

Code:
xft.dpi:   101
xft.antialias: true
!Xft.lcdfilter: lcdfilterlegacy
Xft.hintstyle: hintfull


And then it's possible to pass anti-alias and hinting options individually at:
Code:
URxvt*font:     xft:Inconsolata:autohint=true:antialias=true:size=6


I wonder what's the relationship between .fonts.conf settings, Xft* in .Xdefaults and the fonts sections.

cheers
