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 On Thu, Dec 29, 2011 at 10:18 PM, Hans Hagen wrote: > On 29-12-2011 04:22, Zhichu Chen wrote: >> >> All right, after some readings, I came out with a node solution.

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?

Hi, I wrote some CJK vertical typesetting macros in mkii a long time ago and I want to adopt it to mkiv. Sadly the \iftracechinese is gone. Can I still draw boxes of each glyph to see if they are aligned in my way? Drawing a line in the background is so not cool. -- Best Regards Chen ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
