Xorg::XLFD - X11 logical font description interface
use Xorg::XLFD qw(get_xlfd); my $desc = get_xlfd(); # all descriptions my $fixed = get_xlfd('fixed'); # description for the 'fixed' font
X logical font description is a font standard used by the X Window System. This module provides an interface for accessing these descriptions.
None by default.
get_xlfd() takes one optional argument, a family name. If no argument is provided, all available descriptions will be returned.
An example structure for the standard 'Fixed' font:
fixed => { charset => [ "jisx0208.1983", "iso10646", "iso8859", "koi8", "jisx0201.1976", 0, 120, 180 ], foundary => [ "jis", "misc", "sony" ], horiz_dpi => [ 75, 100, 0, 120 ], pixels => [ 0, 16, 24, 13, 14, 15, 18, 10, 20, 6, 7, 8, 9, "ja", "ko", 12 ], "set width" => [ "normal", "semicondensed" ], slant => [ "r", "o" ], spacing => [ "c", 100, 75 ], tenths => [ 0, 110, 150, 170, 230, 100, 120, 130, 140, 70, 200, 60, 50, 80, 90, 13, 18 ], vert_dpi => [ 75, 100 ], weight => [ "medium", "bold" ], width => [ 0, 160, 240, 70, 80, 90, 60, 140, 100, 40, 50, "c", 120 ] },
The XLFD is made up from 12/14 font properties as visualized below.
-xos4-terminus-medium-r-normal--28-280-72-72-c-140-iso8859-1 | | | | | | | | | | | |__________ charset | | | | | | | | | | |________________ avg. width | | | | | | | | | |___________________ spacing | | | | | | | | |_____________________ vert. dpi | | | | | | | |________________________ horiz. dpi | | | | | | |____________________________ 10th's of 1 pt | | | | | |________________________________ pixels | | | | |______________________________________ set width | | | |__________________________________________ slant | | |_______________________________________________ weight | |________________________________________________________ family |______________________________________________________________ foundary
We are relying on an external application for fetching the available font descriptions. This is not good. We will look at the xlsfonts source code and try to come up with a smarter way.
