Browsers come with font settings. However, these settings are often neglected. Web developer has at least three options for selecting a font which would be displayed by default on your browser screen.
It can be a generic font, "hand picked" local font-family, or on-the-fly downloaded web font. Nevertheless the user still has the choice which font he or she actually wants to use. Reasons: privacy, security, speed, aesthetic.
Preparing the fonts:
MorphOS is bundled with True Type, PostScript and Amiga Bitmap fonts.
OWB uses fontconfig for font handling. Fonts are cached whenever a change in font directories is detected.
If you want to use your fonts exclusively - fonts.conf should only use the path where you store the fonts (for example SYS:Fonts/_ttf).
Fontconfig is a library providing font configuration, customization and application access. It uses freetype library which supports plenty of font formats (excluding Amiga Bitmap fonts).
Presets are stored in the MOSSYS:Fontconfig/conf.avail directory.
FONTS:Fontconfig/fonts.conf (default font dirs)
Code:
<!-- Font directory list -->
<dir>SYS:Fonts/_pcf</dir>
<dir>SYS:Fonts/_pfb</dir>
<dir>SYS:Fonts/_ttf</dir>
<dir>MOSSYS:Fonts/_pcf</dir>
<dir>MOSSYS:Fonts/_pfb</dir>
<dir>MOSSYS:Fonts/_ttf</dir>
Example settings:
FONTS:fontconfig/conf.d/51-local.conf
Code:
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!-- Load local system customization file -->
<include ignore_missing="yes">local.conf</include>
</fontconfig>
FONTS:fontconfig/local.conf (turns off antialias for font sizes smaller than 16 and disables autohint)
Code:
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!-- /etc/fonts/local.conf file for local customizations -->
<fontconfig>
<match target="font">
<edit name="antialias" mode="assign">
<bool>false</bool>
</edit>
</match>
<match target="font" >
<test name="size" qual="any" compare="more">
<double>16</double>
</test>
<edit name="antialias" mode="assign">
<bool>true</bool>
</edit>
</match>
<match target="font" >
<test name="pixelsize" qual="any" compare="more">
<double>16</double>
</test>
<edit name="antialias" mode="assign">
<bool>true</bool>
</edit>
</match>
<match target="font">
<edit name="autohint" mode="assign">
<bool>false</bool>
</edit>
</match>
</fontconfig>
In OWB, go to Settings/Fonts and choose default fonts and sizes.
Blocking remote fonts:
OWB comes with an integrated blocker. Make sure it's enabled (Settings/Content). To disable remote web fonts this line needs to be added to its filter (SYS:Applications/OWB/Conf/blocked.prefs):
*
Quote:
/\.ttf|\.otf|\.woff|\.woff2\?/
A specific font can be whitelisted too:
Code:
@@/*actually-nice-font.ttf
Other platforms:
In theory, the methods above will work on other systems.
Firefox has the option to disallow any other font than set in its preferences.
Chrome and Opera have --disable-remote-fonts option.
Other browsers might need a blocker. uBlock comes with an option to block remote fonts.
Custom filters (like the one above) should work as well.
*This isn't ideal. OWB will try block anything_not_whitelisted.ttf, even if you look for a nicefont.ttf in Google Search.
