mkcfm - create summaries of font metric files in CID
font directories
mkcfm [CID-font-directory-name]
There
is usually only one CID font directory on the X font path. It is usually
called /usr/X11R6/lib/X11/fonts/CID. If you do not specify an argument,
mkcfm will try to go through the subdirectories of that directory, and
create one summary of font metric files for each CIDFont (character descriptions)
file and each CMap (Character Maps) file it finds. The summaries of font
metric files are put in the existing CFM subdirectory. The CFM subdirectories
are created when CID-keyed fonts are installed.
If you specify a CID font
directory as an argument, mkcfm will try to go through the subdirectories
of that directory, and create one summary of font metric files for each
CIDFont file and each CMap file it finds. mkcfm will calculate the summaries
of the font metric files stored in AFM subdirectories of the CID font
directory.
Those summaries are needed by the rasterizer of CID-keyed fonts
to speed up the response to X font calls. If those files do not exist, CID
rasterizer will have to go through usually large font metric files, and
calculate the summaries itself each time the font is called. You will notice
a substantial wait on a call to a large CID-keyed font.
.
- Each CID-keyed
font file is supposed to have a font metric file (.afm file). mkcfm creates
summary files (.cfm files) of those font metric files. mkcfm should be run
whenever a change is made to the files stored in the subdirectories of
the CID font directory. For example, it should be run when new CID fonts
are installed.
.- Summaries of font metric (.afm) files created by mkcfm.
