Dear gang,
For \addfeature and the like, a virtual font feature defined in terms of a CLD
local function behaves differently from other font features. MWE:
==============
\startluacode
local function squeeze(tfmdata)
for k, v in next, tfmdata.characters do
v.width = 1.75 * (v.height or 0)
v.depth = 1.75 * (v.depth or 0)
end
end
local specification = {
name = "sqtfm",
description = "test",
manipulators = {
base = squeeze,
node = squeeze,
}
}
because much more has to be done to satisfy the backend (liek advance
with and such) .. you cannot just change dimensions on the fly for
characters that could potentially be shared just as you can't change
glyph dimension mid document
