The snippet info outputs the exact dimensions of the TeX box. The tightpage option adds additional side bearings to that in order to arrive at the PostScript page size so as not to cut off anything that might slightly protrude out of the TeX box. So the total size of the graphics is larger by those side bearings, and the ascent ratio is also slightly influenced by it. Probably not more than very few pixels at most, if at all. If I call the tp numbers tp1, tp2, tp3, tp4, and the snippet values ht, dp, wd, then we have, strictly speaking, ascent = max(0,ht,-dp)+tp4 descent = max(0,-ht,dp)-tp2 The tightpage dimensions can be modified by the user; in that case, before the next snippet, the changed values will be printed out in a new Tightpage line (the separate prlyx.def that you have had in your hands before printed out the tightpage info itself, and just once at the start of the document. Which should not make a difference, as I don't think anybody ever fiddled with those settings, least of all in mid-document). > ps, If you're planning on releasing preview-latex 0.73 in the next > week or so, then that 's great. It will quite probably not be possible this week, but certainly the next one. We have some documentation issues to sort out, and I have some other stuff (like native XEmacs/Windows support instead of Cygwin) that we want to have basically tested. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum Email: [EMAIL PROTECTED]
