Category: Primitives Group: v1.50.0 Status: Open Resolution: None Priority: 5 Submitted By: The Thanh Han (hanthethanh) Assigned to: Hartmut Henkel (hhenkel) Summary: added \pdfkeeplinedimen primitive
Initial Comment: This patch introduces a new primitive \pdfkeepdimenline, which is an addon to bring some more flexibity to the existing \pdflastlinedepth, \pdffirstlineheight, \pdfeachlinedepth and \pdfeachlineheight primitives. Those primitives are set to 0 by default, and they take effect only if the user sets them to a non-zero value (as one can guess from their names, they fix line dimensions of a paragraph). The issue with those primitives is that it's impossible to use them with 0, as this value means "don't change line dimens". So this patch introduces \pdfkeepdimenline, a dimen register keeping the value for "don't change line dimens". By default all are set to 0, so the default behaviour is unchanged. For example, to set depth of each line after line breaking to zero, one can say: \pdfkeeplinedimen=\maxdimen \pdfeachlineheight=\pdfkeeplinedimen \pdffirstlineheight=\pdfkeeplinedimen \pdflastlinedepth=\pdfkeeplinedimen \pdfeachlinedepth=0pt Testing/comments welcome. ---------------------------------------------------------------------- Comment By: Nobody (None) Date: 2007-06-23 19:29 Message: Logged In: NO This is completely clunky and awkward. Instead of having some magic variable which changes the meaning of _all_ addresses here, how about just using \prevdepth's default for "no change", namely -1000pt? ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=495&aid=812&group_id=106
