Subject: reencode fonts with fonts.trigger
Date: Tue, 22 Feb 2011 16:22:00 +0100 [thread overview]
Message-ID: <1o57kg5y2iy7y.dlg@nililand.de> (raw)
Hello,
Khaled had another idea to manipulate (reencode) fonts: He suggested
to put a function in fonts.trigger. (Example below). I have some
questions regarding this example:
1. Is there a basic flaw in the idea?
2. Is the interface more or less stable or will it probably change
in the future?
If not
3. which tables/values in tfmdata must be copied/reassigned beside
the indices information? (There seem to be quite a lot informations
more than once in tfmdata. E.g. I find the boundingbox in two places
(descriptions and shared.otfdata.glyphs)).
4. Which tables/values must be created if I try to move a char to a
place which is currently empty (like the "z" in the example)?
5. What is the recommanded lua-code to copy/reassign/remap the
tables? Does a library or some helper functions exist which would
make it easier to move the tables around?
\directlua{
local function chess(tfmdata,value)
if value then
tfmdata.characters[122]={}
tfmdata.indices[75],tfmdata.indices[81],tfmdata.indices[122]=tfmdata.indices[81],tfmdata.indices[75],tfmdata.indices[81]
table.tofile("filechess.lua", tfmdata, true) %show table
end
end
table.insert(fonts.triggers,"chess")
fonts.initializers.base.otf.chess = chess
fonts.initializers.node.otf.chess = chess
}
\font\test="file:SkakNew-Figurine.otf:chess=yes"
\starttext
\test KQzK
\stoptext
\bye
