[geda-user] Fonts for PCB Designer

[Erich Heinzle]

I have converted some of the free Hershey fonts for use with PCB.

I started with Hershey Sans 1 stroke to provide a more contoured font.

In the process I wrote a small piece of C code psbFontTool.c to simplify
processing of pstoedit outputs and conversion into PCB Designer compatible
font symbols.

Having streamlined the process somewhat, I figured why not do some of
the other fonts, so, PCB users now have the choice of:

Hershey Sans 1 stroke
Hershey German Gothic
Hershey Italian Gothic
Hershey English Gothic
and the usual default_font

I have uploaded the fonts, the pcbFontTool utility, and instructions for
those
wishing to convert other fonts, to an ftp server

users.on.net/~esh/geda/pcb/src/fonts/

If someone with git credentials could commit them, that would be
appreciated.

If there are any users keen on having the Hershey cyrillic or greek glyphs
converted I can convert them too, or if users have a FOSS centerline
aka 1 stroke font they would like converted, I can give it a go.

Cheers,

Erich

Well done, I had this job on my TODO list since long time, now I can remove
it ;)
I think it would be nice to have the option to change silk fonts in PCB,
for example specifying the symbols file to apply to the layout...

Cool stuff! But before they can be committed anywhere, some comments...

* commit *where*? The url just has a few files with no README or
diff. The typical git process would be for you to "git
format-patch" to extract your local commit of the files into an
email that someone else could commit upstream.

* You specify GPL 3 but pcb uses GPL 2. While normally this isn't a
problem, using a different license may result is confusion or
perhaps legal problems later on.

* "PCB Designer" is Allegro's layout tool. gEDA's tool is just "PCB"
or "gEDA/PCB".

* Could you give some examples of how PCB can use a non-ASCII font?
We haven't added support for UTF or (officially) Latin-1. Or does
the user need to know how to map ASCII symbols to different glyphs
in your fonts? If so, that mapping would need to be documented too.

* We'd also need a diff for all the Makefiles and stuff to make sure
the *.c is built and everything is included in the distribution
tarball.

[Erich Heinzle]

I have revised the license to GPL v2 to simplify things.

My bad on the terminology for PCB, I'd seen it referred to as such amongst
geda PCB instructions somewhere, I thought. I have fixed that.

These fonts are a simple drop in replacement for default_font, which at
this stage lives in /geda/pcb/src
So, no UTF is needed.

In the absence of a mechanism for selecting fonts in PCB, the only idea I
had was a subdirectory in src named fonts

The utility is standalone, only uses stdio, and has an attached README.txt

users.on.net/~esh/geda/pcb/src/fonts/README.txt

for some reason the FTP server does not like listing README.txt or README
files.

The gothic and sans fonts use the normal ASCII/US keyboard mapping

The cyrillic font uses a keyboard mapping based on the Hershey fonts as
distributed.
There are four or more types of cyrillic keyboard mapping, so I have just
thrown in a glyph table to assist anyone
trying to use it.

This is my first bit of c code that does anything useful, so makefiles
might take a bit of time, but I'll give it a crack.

I will try and do a diff on on my local filesystem changes and submit it,
but it will be ~ 0.5MB.

Cheers,

Erich

It might be more future proof (assuming you don't mind the GPL3 or later
as a future option), to have a document stating the licensing as
follows:

"
This program is free software; you can redistribute it and/or modify it
under the terms of the GNU General Public License as published by the
Free Software Foundation; either version 2 of the License, or (at your
option) any later version.
"

The "(at your option) any later version." clause may be useful, if at
some future point we are forced to move to GPL3 due to the viral
influence of various libraries / projects we might want to depend upon -
notably those owned by the FSF/GNU project.

(In practice, I think gEDA/gaf ends up being distributed under GPL3, due
to Guile versions being GPL3 now).



I'm NOT a big fan of the FSF, or the GPL3, and I see a number of open
source CAD packages / libraries stuck in license limbo because they use
GPL2/LGPL2 (due to their existing codebase / lawyers / whatever), and
thus cannot use various GNU / FSF copyright owned packages which have
been automatically bumped to GPL3/LGPL3.

It really stings, and feels wrong that a GPL2 program and a LGPL3
library are incompatible. Linking exception anyone?

Good point. Indeed I saw that term 'Designer' multiple times on this
list -- and for Gentoo we have an icon which displays the name 'PCB
Designer'

I am not sure if that icon is provided by pcb developers or gentoo
people:

It's in the git repo but should be corrected.

This is great!
With this method I think it's possible to put Chinese characters on PCB.

There's a standard for Chinese characters for CAD stuff.
Standard Number: GB/T 13844-1992
Vector Danxian songti font set and data set of Chinese ideogram for
graphics information interchange
http://www.freestd.us/soft/181203.htm

The characters looks like this -
https://www.flickr.com/photos/atommann/14883660247/

It's a vector font. But as far as I know there's no open source
version of this font.

[Erich Heinzle]

I have now uploaded a one stroke greek font, and a cyrillic font, to the
FTP site, along with glyph tables to allow people to figure out the
keyboard mapping.

I have no experience with asiatic languages, but the jpeg link atommann
provided looked interesting, describing a standard chinese CAD font.

I created a path for pictogram 01 shown, and exported as an eps, then ran
pstoedit, and then used pcbFontTool to generate a default 4000 mil
character.

I have attached a quick example pcb file below, with the pictogram mapped
to the left quote (under the tilde, usually maps to a blank rectangle in
PCB)

at 4000 mil default font height it isn't very legible at all, but if a
larger default font size were used in the final scaling then the pictogram
would be legible without zooming.

zooming in and out with S or shift+S will give you an idea.

I could slowly trudge my way through the jpeg atommann linked to and create
a gEDA PCB one stroke pictogram font, but gEDA PCB's text object will need
to be modified to accept a parameter indicating a particular font file and
an index of 00...94 in the case of the GB/T 13844-92 cad standard chinese
font pictograms.

If there is a way to make such pictograms usable by text objects (maybe its
easy with the PCB code, I don't know), and if a chinese reader can do QA on
my work output, I could convert them to a PCB compatible font.

Cheers,

Erich,

[Erich Heinzle]

just as a worked exercise, I tried turning pictograms 1-9 into line data
then symbols:

users.on.net/~esh/geda/pcb/src/fonts/experimental/ChinesePictograms1-10.pcb

feel free to download and play, they are mapped to numbers 1-9 and have
been zoomed up somewhat. They're not really legible below a height of
100-120mil

These symbols have been created without bezier curve paths. With curved
paths, the symbol definitions were about 3 times the size.

the issue is now
- legibility QA on the pictograms by someone who can read them
- how to be able to refer to them from within a text object

the same issue affects accents on the greek font, which need at least
another 10 symbols for the simplest accenting system

similarly for german, umlauts would be good

a slightly more flexible way to refer to commonly used non ascii
characters as an index into a font file or extended symbol definitions in
addition to the usual ones within the pcb file itself would probably be
"good enough" for PCB users, and may be simpler than trying to implement
unicode etc..

Cheers,

Erich

Hi,

Post by Erich Heinzle
If there are any users keen on having the Hershey cyrillic or greek

glyphs

Post by Erich Heinzle
converted I can convert them too, or if users have a FOSS centerline
aka 1 stroke font they would like converted, I can give it a go.

This is great!
With this method I think it's possible to put Chinese characters on PCB.
There's a standard for Chinese characters for CAD stuff.
Standard Number: GB/T 13844-1992
Vector Danxian songti font set and data set of Chinese ideogram for
graphics information interchange
http://www.freestd.us/soft/181203.htm
The characters looks like this -

It's a vector font. But as far as I know there's no open source
version of this font.

Best regards,
