[SOLVED] Iceweasel4(firefox): cannot enable anti aliasing

deepclutch · 05-23-2011, 05:22 AM

Hi,
I have a Debian Testing System. I installed Iceweasel4(Firefox4) from experimental repository and it works fine except for enabling font anti aliasing. fonts looks slim..narrow to Me while the Other browser I use is a webkit based browser "Midori" which renders font anti aliasing fine.

I have Anti Aliasing,subpixel rendering,lcd cleartype patch etc all enabled and whole system font rendering anti aliasing working.

Regarding Cairo,xft all are "supported" versions . about:buildconfig of Iceweasel 4 also shows it was compiled against cairo library.

Help Needed.
TIA+

Solved!: I checked the hintstyle parameter in ~/fonts.conf .

I corrected the hintstyle from hintfull to hintnone OR hintslight and Iceweasel font rendering got anti aliasing fine.

While "hintmedium","hintfull" makes fonts look awful.Any idea why this system needs hintstyle to hintnone?

Quote:

Hint style

Hint style is the amount of influence the hinting mode has. Hinting can be set to: hintfull, hintmedium, hintslight and hintnone. With BCI hinting, hintfull should work best for most fonts. With the autohinter, hintslight is recommended.

Code:

<match target="font">
    <edit name="hintstyle" mode="assign">
      <const>hintfull</const>
    </edit>
  </match>

My Corrected ~/.fonts.conf:

Code:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!--  Enable sub-pixel rendering --> 
  <match target="font">
    <edit name="rgba" mode="assign"><const>rgb</const></edit>

  <match target="font">
    <edit name="antialias" mode="assign">
