weight The font weight, e.g., 80 for regular, 200 for bold.
slant The slant, usually 0 for none, 100 for italic.
file The name of the file containing the font.
outline true for outline fonts, false for other fonts.
scalable true for scalable fonts, false for other fonts.
bitmap true for bitmap fonts, false for other fonts.
pixelsize Font size in pixels. In connection with fc-list, this option
only makes sense for bitmap fonts.
X11 Core Fonts
Today, the X11 core font system supports not only bitmap fonts but also
scalable fonts, like Type1 fonts, TrueType and OpenType fonts, and CID-
keyed fonts. Unicode fonts have also been supported for quite some time.
In 1987, the X11 core font system was originally developed for X11R1 for
the purpose of processing monochrome bitmap fonts. All extensions men-
tioned above were added later.
Scalable fonts are only supported without antialiasing and subpixel render-
ing and the loading of large scalable fonts with glyphs for many languages
may take a long time. The use of Unicode fonts may also be slow and re-
quires more memory.
The X11 core font system has a few inherent weaknesses. It is outdated and
can no longer be extended in a meaningful fashion. Although it must be
retained for reasons of backward compatibility, the more modern Xft and
fontconfig system should be used if at all possible.
Only directories meeting the following requirements are considered by the
X server:
Directories entered as FontPath in the Files section in the file
/etc/X11/XF86Config.
Directories that have a valid font.dir file (generated by SuSEcon-
fig).
Directories that are not disabled with the command xset -fp when
the X server is active.
Directories that are not enabled with the command xset +fp when
the X server is active.
