.SH NAME
pktype \- translate a packed font file for humans to read
.SH SYNTAX
.B pktype
.I pk_file_name
[
.I output_file_name
]
.\"=====================================================================
.SH DESCRIPTION
The
.B pktype
program translates a packed font file
.RI ( pk )
(output by, for example,
.BR gftopk (1)
to a file that humans can read. It also serves as a
.I pk
file-validating program (i.e., if
.B pktype
can read it, it's correct) and as an example of a
.IR pk -reading
program for other software that wants to read
.I pk
files.
.PP
The
.I pk_file_name
on the command line must be complete. Because
the resolution is part of the extension, it would not make
sense to append a default extension as is done with \*(TX or
DVI-reading software. If no
.I output_file_name
is specified, the
output goes to the
.IR stdout .
.PP
The output file gives a compact encoding of the packed encoding, using
conventions described in the source code. Run lengths of black pixels
alternate with parenthesized run lengths of white pixels, and brackets
are used to indicate when a row should be repeated.
.\"=====================================================================
.SH ENVIRONMENT
.B pktype
looks for
.I pk_file_name
using the
environment variable PKFONTS.  If that is not set, it uses the variable
TEXPKS.  If that is not set, it uses TEXFONTS.  If that is not set, it uses the
system default:
.br
.I @DEFAULT_PK_PATH@
.PP
See
.BR tex (1)
for the details of the searching.
