Re: [NTG-context] Is there a replacement for \tracechinesetrue in mkiv?
Well, that's just perfect, only it's not what I'm looking for :( What
I need is a fully customable way to debug some of my inputs rather
than everything as a font feature.
I found a cleaner way now: to use the whatsit node, I hope it's
useful for someone so I paste the function here:
local function trace_boundingbox (head)
for n in node.traverse (head) do
if n.id == node.id ('glyph') then
local ht,wd,dp = n.height,n.width,n.depth
local htsp,wdsp,dpsp = ht/65536,wd/65536,dp/65536
local w = node.new(whatsit,pdf_literal)
w.data = q 1 0 1 RG 1 0 1 rg 0.1 w 0 .. -dpsp .. m 0
.. htsp .. l .. -wdsp .. .. htsp .. l .. -wdsp .. ..
-dpsp .. l s 0 1 0 RG 0 1 0 rg 0.1 w [2 1] 0 d 0 0 m .. -wdsp ..
0 l S Q
node.insert_after (head, n, w)
end
end
end

dirty. I prefer mplib but I have no clue how to do that.
Using mp would be pretty complex too and all solutions are rather
inefficient (bloat the pdf) .. attached another solution (I'll add it to the
next beta).

Drawing a line in the background is so not cool.
mkiv does things completely different

Re: [NTG-context] Is there a replacement for \tracechinesetrue in mkiv?
Interesting, so I guess I should write some lua code? Since I have little experience in that area, could you provide a minimal example just to show me how to draw the baseline of each glyph?
