* Is there a replacement for \tracechinesetrue in mkiv? @ 2011-12-21 11:16 Zhichu Chen 2011-12-21 22:47 ` Hans Hagen 0 siblings, 1 reply; 7+ messages in thread From: Zhichu Chen @ 2011-12-21 11:16 UTC (permalink / raw) To: mailing list for ConTeXt users 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 ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 7+ messages in thread

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?
