Postscript Type1 fonts on the Amiga - (at last!)
type1.library
t1manager

WARNING: This is still what I would call 'beta' software!
Be wary! There are known problems/incompatibilities!!
I will not be held responsible for any problems, etc.

INTRODUCTION
The files in this distribution implement a Postscript Type1 font
engine for the Amiga. It is designed as a shared library that
does for type1 fonts what 'bullet.library' does for compugraphic
fonts. In addition, a program 't1manager' is included, which is
required to install, remove, and preview type1 fonts.
NOTE: t1manager REQUIRES MUI. I think that it will work with
any version of MUI from 1.2 to 2.2. I'm quite sure that it will
work with MUI 2.0 onwards.
NOTE: both programs require AmigaDOS 2.1 or higher. I honestly
am not perfectly sure anymore about 2.0 (or 2.1). I'll say that
if your system supports Compugraphic fonts, then I think
type1.library and t1manager should work.
###########################################################################
INSTALLATION and USAGE
First of all, there are two versions of the library - one compiled for
68000 and no math coprocessor (which should run on any Amiga), and
one compiled for 030 AND 68882 math coprocessor. Pick the one you
intend to use.
To install, do the following from the shell, or the equivalent from WB.
CD <this directory>
COPY libs/type1.library.0x0 libs:type1.library ; 000 or 030
COPY t1manager/t1manager sys:system ; or wherever
COPY t1manager/t1manager.info sys:system ; copy icon
Now, you should be ready to install postscript fonts. Do this by
running the 't1manager' program.
What I do, is I have a drawer called Apps:type1fonts, which
is part of my FONTS: assign. I accomplish this by having the
following line in my user-startup file:
ASSIGN fonts: apps:type1fonts ADD ; Note the ADD
Now, when you run t1manager, you can select the font drawer
to use.
You install a font or fonts by clicking on install and selecting
the font or fonts to install. These must be binary type1 postscript
files. They commonly end in '.pfb'. There are several programs on
Aminet that I've seen that will convert different postscript font
formats to .pfb format. Find one, if your favorite font doesn't
install.
IMPORTANT!!! The installer does NOT actually copy the binary file
into the fontdrawer!!! (unlike Intellifont/Fountain). It creates
the .font and .otag files (and an empty directory) in this drawer.
The actual binary file must not be deleted, or moved, or else the
font will stop working. The .otag file simply refers to the font
whereever it is. Thus, if you have some postscript fonts as part
of some application, say Pagestream, you don't have to have two
copies - type1.library will read the font directly from the
directory it was in when you installed the font.
To see a preview of an installed font, just double click on the font's
name. The preview will appear on the bottom panel.
Etc.
At this point, barring bugs, you should be able to select postscript
fonts wherever you would otherwise select compugraphic fonts.
BETA: Note, however, that as of this beta version, there are still
some substantial incompatibilities... Be forewarned.

WARNINGS/DISCLAIMERS/COPYRIGHT STUFF
###########################################################################
I don't have the time or desire to understand any of the legal
mumbo jumbo that's supposed to go here. So what I'll put here
will be in plain english and not legalese:
First of all: you can't sell this for money - note carefully
the 'without fee' clause in the following blurb. Insofar as
the notice below permits, I think that the interpretation
should be that Fred Fish-type prices for distribution are
okay; selling this software by itself, or as part of a package
where this software is part of the advertisement, is not okay.
Also: I disclaim any responsibility for anything regarding
type1.library, t1manager, or any associated files, usage, etc.
In other words, if anything goes wrong, it's not my fault. In
fact, I'll just say that it is likely that things will go wrong
- if you choose to use or look at this software, be forewarned,
and don't blame me!!
Furthermore, I don't claim too much credit for the software here:
I just used, copied, modified and am now distributing software
that was donated to the X Consortium by others. The underlying
font engine was written apparently for use with X-windows servers-
I didn't write it, and don't claim exceptional knowledge about it.
Here's the blurb that I think I'm obligated to add here:

The above applies only to portions of the code that contain the message
at the top of the source. Other source files (of which *some* begin with
my first name; hey, what can I say :-> some people choose to use foo
and bar - I use my first name!) were written by me, and probably contain
Amiga-specific code. For these files, the same license to use, copy, etc.
and the same proviso regarding warranties applies, with AMISH S. DAVE
substituting for IBM, LEXMARK, and ADOBE.
Also, I used some enhancements to the X windows code provided by HP:

ENHANCEMENTS.

WHERE DID IT COME FROM?
I started with the postscript rasterizer in the contrib distribution
of X11R5 (X-Windows). I have since used the X11R6 type1 font rasterizer,
which is part of its core distribution. I have also used some patches
by HP that were on the ftp.x.org ftp site in the contrib section.
What I did was adapt it to look like the Amiga's compugraphic
font engine (bullet.library). My only source of information on
writing such libraries was from the includes and by looking at
what was being passed to and from bullet.library when diskfont
called it (by SetPatch()-ing bullet.library).
After adapting the code to the Amiga, I sped it up, by re-writing some
portions of the code, tweaking other portions, etc. In some cases, I
wrote assembly routines to replace C code. These were my first 680x0
assembly routines...
Then I whipped up a MUI utility to install/remove/preview fonts. This
was also my first MUI program.
###########################################################################
WHERE IS IT GOING
I haven't had the time to work on this 'pet project' for a while. I
don't anticipate finding the time in the near future. Thus, I'm
releasing now so as to encourage further development by others. I
personally consider this software to be at a 'beta' level - it certainly
isn't polished enough yet for a 1.0 release, I think.
Hopefully, people will start working on this now. I ask that people
who work on this to please make public, or send me any updates or
changes they make. My intention is for there to only be a single
type1.library for the Amiga, not a confusing litany of 14.15XYZ,
1.0K00L, ABC2.0 versions, each somewhat different... That would suck.
###########################################################################
KNOWN PROBLEMS
Most of the problems remaining stem from my not correctly supporting
the glm_Width field of the glyphmap structure that I return. Right
now I put 1.0 for every character. Also, there are many tags that I
don't support yet. The TODO file accompanying this release lists a
few of the more important changes that need to be made.

(:->) and bug reports.
