.IX Title "PFM2KPX 1"
.TH PFM2KPX 1 "fontools" "2005-07-29" "fontools"
.UC
.SH "NAME"
pfm2kpx \- extract correct kerning information from \fIpfm\fR 
(Printer Font Metrics) files
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
pfm2kpx [options] \fIpfm\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Many PostScript Type1 fonts contain only
\&\fIpfb\fR and \fIpfm\fR files, but no \fIafm\fR (Adobe Font Metrics) files. These can be
generated with \fIpf2afm\fR (which comes with \fIGhostScript\fR), but
this might not yield all kerning pairs from the \fIpfm\fR file. The reason
for this is that \fIpf2afm\fR interprets \f(CW\*(C`dfCharSet = 0x00\*(C'\fR to mean that
the Adobe StandardEncoding has been used, whereas many fonts (or font
creation tools) instead use the Windows \s-1ANSI\s0 (aka codepage 1252) encoding.
(You know you've hit this problem when \fBpf2afm\fR complains "\f(CW\*(C`.notdef 
character ocurred among kern pairs \-\- you'd better check the resulting 
AFM file\*(C'\fR".) In this case, the resulting \fIafm\fR is incomplete and contains
wrong kerning pairs.
.PP
\&\fBpfm2kpx\fR extracts the correct kerning pairs from such \fIpfm\fR files and
repairs the \fIafm\fR (if necessary creating it first by running \fIpf2afm\fR).
If for some reason it can't update the \fIafm\fR, it prints the kerning pairs to
\&\f(CW\*(C`stdout\*(C'\fR instead.
.PP
When \fIpf2afm\fR doesn't complain about the kerning pairs, \fBpfm2kpx\fR 
thinks the resulting \fIafm\fR file is fine and quits; this can be
changed by specifying the \fB\-f\fR option (see below).
