t1tools is a collection of programs and batch files useful for
handling type 1 fonts on MSDOS and Unix systems.
Documentation is ad-hoc to get the package out at last - sorry for
any inconvenience this may impose. The package is not meant for
people without knowledge about type 1 font and metrics stuff.
If you detect any incompleteness or have any suggestions for improvement,
please tell me.
Thomas Wolff@inf.fu-berlin.de
The package is available by anonymous ftp:
ftp.fu-berlin.de: pub/postscript/t1tools.zip
The package contains the following tools:
makeafm.bat (MSDOS)
makeafm (Unix)
Generates an .afm font metrics file from a .pfb font file.
The information is taken directly from the font itself by
first disassembling it using an appropriate program.
If pair kerning information is available from any previously
existing .afm or .pfm file for that font it will be included
in the generated .afm file.
Syntax: makeafm font-file-base
Don't include .pfb / .pfa suffix in file name.
Examples:
makeafm photina
Disadvantage: character bounding box information will not be
included. This does not matter for use with FrameMaker (which
I originally wrote the script for), but for some Tex-ps adaptations.
The MSDOS version, however, does at least include simulated character
bounding box information derived from other font information to
enable Adobe's makepfm to work on the .afm file.
Required:
1. To disassemble the type 1 font (.pfb file):
the program t1disasm from the package t1utils posted by
I. Lee Hetherington with the following modification to t1disasm.c:
look up the line output(" {\n");
at the beginning of the routine do_charstring and remove the \n .
2. To extract pair kerning information from .pfm files on MSDOS:
a) either the program pfm2afm
b) or the program dumppfm (version 1.5.3)
(Extraction from .pfm files works without additional software on Unix.)
getmetri.bat (MSDOS)
getmetric (Unix)
Generates an .afm font metrics file by interpretation of the font
using GhostScript. Like makeafm, this script will try to include
kerning information from previous sources.
Syntax: getmetric font-file-base [/FontName]
Don't include .pfb / .pfa suffix in file name.
Explicit /FontName can choose among several fonts in file.
Examples:
getmetric photina
getmetric hvn_____ /Helvetica-Narrow
Disadvantage: GhostScript in its current version still has a bug
which causes incorrect width information to be calculated for
characters composed by seac and having a different width from their
base character - actually, this should not be allowed according to
the type 1 font specification, but to accomodate existing fonts to
work, rather Adobe's "Do what we implement" semantics should be
realized. The problem especially occurs with fonts bundled with
Micrografx Designer (which even compose characters like double
qoute marks from single quote marks etc), so don't apply getmetri
on them.
Required: GhostScript
getmetri.ps (enclosed), which is a corrected and enhanced
version of the PostScript program posted by W.T. Roberts
and Bryan Bayerdorffer.
pfbshow.bat (MSDOS)
gpreview (Unix)
preview (Unix)
pfbpr.bat (MSDOS)
preprint (Unix)
[preview and preprint differ from gpreview only by their name and
can be created by setting respective links.]
Generates a sample text and character set listing of up to four
fonts (preferably of one family).
The latter two print, the first three display on screen.
Syntax: pfbshow fontfile1 [fontfile2 [fontfile3 [fontfile4]]]
pfbpr fontfile1 [fontfile2 [fontfile3 [fontfile4]]]
preview (fontfile|fontname) ...
Up to four fonts make sense. The Unix scripts can accept
FontNames instead of file names to explicitly select a
font which must then be previously known to the interpreter.
Examples:
pfbshow photina.pfb
pfbshow photina photinai photinab
gpreview Times-Roman.pfb /Hershey-Roman
Required:
one of several .pfb/.pfa converters (e.g. from t1utils)
pfbshow.bat, pfbpr.bat: pfshow.ps (enclosed)
pfbshow, gpreview, pfbpr: GhostScript
preprint: a PostScript printer
preview: a type 1 font emulation package for OpenWindows
and a font disassembler (e.g. from t1utils)
(or maybe, native type 1 font interpretation in
OpenWindows 3.1 which I don't have)
pcs.bat (MSDOS)
Display the character set of a font in comparison with that of
an installed reference font (or a second font) including a
coloured width and slant angle box. It can be used to judge
quality, similarity, and correct/incorrect character set assignment
of fonts.
Syntax: pcs filename [filename2]
Examples:
pcs gocmase_.pfb
pcs agar agarsc
pfblist.bat (MSDOS)
Generates a list of file and font names of the current directory.
Requires: pfbnames.pas/.exe (enclosed)
afm-pfm.bat (MSDOS)
Generates .pfm from .afm files using Adobe's makepfm program.
Generates .inf information as needed for makepfm. Also tries
to extract the correct Bold/Italic combination from .afm information.
Can be called with explicit information about the Windows menu
font name and Bold/Italic combination to be used.
Syntax: afm-pfm fontfile [MSMenuName | - ] [N | I | B | T]
Don't include .afm suffix in fontfile.
MSMenuName selects a name under which the font should appear
in MS Windows menus for most programs if this is different
from the FamilyName in the .afm file. (Annoyingly, only
4 fonts can be grouped under one name in MS Windows.)
N forces the generated style information to be normal,
I italic, B bold, T bold-italic.
Examples:
afm-pfm agar
afm-pfm agarb AGaramondBold N
If the MS menu name to be generated should contain blanks, an .inf
file must be generated first and the name inserted there.
Required: makepfm.exe from Adobe's "font foundry".
afm-inf.bat (MSDOS)
Part of afm-pfm, can also be called separately.
Example: afm-inf agar
afm-sort.bat (MSDOS)
Sorts the pair kerning list within an .afm file. Needed for some
.afm files to prevent Adobe's simple-minded makepfm program
from crashing.
Example: afm-sort agar
pfb-abf.bat (MSDOS)
Generate .abf files for 72x72 resolution as required to generate
FrameMaker screen font files for use on Sun workstations.
Syntax: pfb-abf fontname [outnam [resolutionx [resolutiony [encoding]]]]
Don't include .pfb suffix in fontname.
If fontname is longer than 6 characters a unique outnam with
at most 6 characters must additionally be specified (five if
you should generate point sizes > 99).
Screen resolution defaults to 72x72 (for Sun workstations)
but can be changed.
The encoding vector to be applied (to be given without its
.enc suffix) defaults to fontname.ENC if that exists,
C:\Adobe\APPLE.ENC otherwise (adapt the path in the script
to where you place the APPLE.ENC file enclosed).
The set of point sizes to be generated defaults to
10 12 14 18 24 but may changed by the environment variable
SIZES, e.g. (for display fonts) set SIZES=18 24 36
Note that FrameMaker needs at least sizes 18 and 24.
Required: makebit.exe, makeabf.exe from Adobe's "font foundry".
pfb-sfp.bat (MSDOS)
Generate HP Laserjet soft fonts from .pfb fonts.
Syntax: pfb-abf fontname [outnam [resolutionx [resolutiony [encoding]]]]
Don't include .pfb suffix in fontname.
If fontname is longer than 6 characters a unique outnam with
at most 6 characters must additionally be specified (five if
you should generate point sizes > 99).
Printer resolution defaults to 300x300.
The encoding vector to be applied (to be given without its
.enc suffix) defaults to fontname.ENC if that exists,
C:\Adobe\foundry\W.ENC otherwise (adapt path in the script).
The set of point sizes to be generated defaults to
10 12 but may changed by the environment variable PSIZES,
e.g. set PSIZES=9 10 12 14 18
Required: makebit.exe, makeljf.exe from Adobe's "font foundry".
pfb-enc.bat (MSDOS)
Extracts an .ENC encoding description from a font specific encoding
vector for use with pfb-abf or pfb-sfp.
Example:
pfb-enc agarexp
fm.ps
A one-liner. Prepended to FrameMaker generated PostScript files
it makes them work with GhostScript.
compose.bat (MSDOS) (not included)
This script calculates positions of accent marks and other
character parts to be composed for composed characters.
It can be used as batch file or interactively, enabling
visual correction of character slant values, accent distance, etc.
The program (actually, compose.ps) generates output usable by my
"t1tidy" program which will then generate according characters
into the font.
Since the interactive version has not been developed to a state
I would like to see posted publically (I have only used it myself
for a few fonts) it is not included in the ftp-able package but
I will mail it to anyone who states interest.
Debugging: All MSDOS scripts accept an additional first parameter "-"
in which case they do not delete their intermediate files.
Remark: Due to that silly MSDOS path restriction, all my MSDOS scripts
(.bat files) contain full path names for several programs. These will have
to be adapted to your installation. Also, for pcs, a reference font will
have to be chosen and installed in the script.
