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. ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=495&aid=812&group_id=106
