After further investigation, I bumped into:
http://stackoverflow.com/questions/10866240/adobe-font-metrics-for-standard-pdf-fonts-in-cp1252
pdfafmdata.ml is basically the contents of the linked zip file, which
comes with a notice:
This file and the 14 PostScript(R) AFM
files it accompanies may be used, copied,
and distributed for any purpose and without
charge, with or without modification,
provided that all copyright notices are
retained; that the AFM files are not
distributed without this file; that all
modifications to this file or any of the
AFM files are prominently noted in the
modified file(s); and that this paragraph
is not modified. Adobe Systems has no
responsibility or obligation to support the
use of the AFM files.
IMHO, CamlPDF violates these terms by not distributing the notice with
the AFM data.
It looks like you're right -- I'll push something to fix this tomorrow,
either in the license file, the source file, or both.
To answer your earlier points (I forgot your email until now -- sorry):
a) It's hard to rely on an external miniz.c, because the configuration
happens in the miniz.c file itself, by changing macros at the top.
b) The change to camlzip is, in essence, just replacing "#include
<zlib.h>" with "#include <miniz.c>". In CamlPDF, I removed other bits of
CamlZip I don't use to reduce binary size, but in the next version, I
will try another solution -- perhaps patching it at build time from
virgin source.
The reason I don't rely on external software and copy source files
directly is that I need customers to be able to compile our pdf command
line tools on a system with just OCaml installed. For example, our
biggest sale last year was to a customer running HP/UX, and I can't risk
those sales by making it harder for them to compile.
You're right that it's not ideal for the open source release though.
With Thanks,
John Whitington
