Add warnings when wrapping multiple fonts and on PCF fonts
commit 1fa97fdc6dc900728be8523be89096b4cb117d4d
Author: Christopher Zimmermann <madroach@gmerlin.de>
Date: Sun Jul 12 15:36:18 2020 +0200
provide version 5 OS/2 table
this was an attempt to fix linespacing, which did not help, but
would still keep it around to avoid double efforts.
commit facf71184163d50adf0b8fccffcaffa18b7bd277
Author: Christopher Zimmermann <madroach@gmerlin.de>
Date: Sun Jul 12 15:12:59 2020 +0200
use design metrics in eblc instead of calculated metrics
This will probably not work for a font providing multiple strikes.
But .bdf fonts don't provide multiple strikes (or do they?!?)
I don't know about .pcf fonts, but I would recommend against running fonttosfnt
on .pcf fonts because bdf2pcf seems to loose some attributes during conversion.
commit 9fb05de7d6c57d045b4a88516f3c28cf3cf98722

Author: Christopher Zimmermann <madroach@gmerlin.de>
Date: Tue Jun 16 18:43:12 2020 +0200
correctly set OS2 fsSelection for italic and bold fonts
commit 1df352c9e862686692ac053b838d76a36d721805
Author: Christopher Zimmermann <madroach@gmerlin.de>
Date: Mon Jun 15 14:08:49 2020 +0200
truncate foundry if there is no known abbreviation.
Honestly I have no idea why the foundry needs to fit in four bytes.
But anyway truncation might indeed be better then "UNKN" ?
Anyone more knowledgeable than me out there?
commit 8532812f1eddfadc0bcfad220b283bf5990bba10
Author: Christopher Zimmermann <madroach@gmerlin.de>
Date: Sun May 31 08:02:24 2020 +0200
use zero lineGap, sTypoDescender should be negative
According to
https://simoncozens.github.io/fonts-and-layout/opentype.html#vertical-metrics-hhea-and-os2
sTypoDescender should be negative and lineGap should be zero.
commit de8068f9c4251fb6cb9407c07bf245e1937270bc
Author: Christopher Zimmermann <madroach@gmerlin.de>
Date: Sun May 31 07:58:10 2020 +0200
don't add arbitrary number to the glypth metrics
This caused pango to calculate wrong, too large font extents and in
consequence gvim used too large character cells.
commit 7096c58f3fe3b6c79508cb16daac5c5bb2f042e7
Author: Peng Wu <pwu@redhat.com>
Date: Thu Jun 11 14:09:35 2020 +0800
Guess Regular style for Medium Weight
X Logical Font Description recognize "Medium" as "Regular".
Update the faceWeight function to change style from "Medium" to "Regular".
commit 81a61c049e6de80120531f0770b22e7637c9acb9
Author: rnhmjoj <rnhmjoj@inventati.org>
Date: Fri Feb 7 17:47:52 2020 +0100
Fix uninitialised memory write
If macTime() fails write zeros instead of unitialized memory to
the date fields.
commit 51e8117654fb092ae5412d7aa184bfc6b498c954
Author: rnhmjoj <rnhmjoj@inventati.org>
Date: Fri Feb 7 17:46:54 2020 +0100
Fix incorrect error handling in macTime()
mktime() and time() return (time_t -1) to signal an error.
Checking for negative values will incorrectly assume an error
happened for any calendar date before the unix epoch.
