Hi, while comparing the PDF of mkii and mkiv I noticed a slight differ in the boundingboxes (bb) of MP figures. While all mkii bb have the form [0 0 w h], the mkiv counterparts use [-1 -1 w+1 h+1]. So the bb of mkiv is enlarged 1bp in all directions. Is this intended? Minimal example and PDF attached. (ConTeXt 2009-04-06; luatex0.37; pdftex1.40.9; mpost1.102) Best wishes, Peter \pdfcompresslevel0 \setuppagenumber[state=stop] \startuniqueMPgraphic{foo} fill unitsquare xyscaled(2in,1in); \stopuniqueMPgraphic \starttext \null \useMPgraphic{foo} \stoptext

harmless ... it prevents clipping of lines \setbox0\hbox{\useMPgraphic{foo}} \the\wd0 \the\dimexpr2in\relax \box0 the real dimensions and positioning is ok ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

harmless ... it prevents clipping of lines mh, you mean if something is \framed (with default frame settings)?
\setbox0\hbox{\useMPgraphic{foo}} \the\wd0 \the\dimexpr2in\relax \box0
the real dimensions and positioning is ok
i haven't seen any problems here so far and my default unit (px) is smaller than one bp. i was just wondering.... :) thx for the info.

if the bbox goes through the middle of a line in an xform then you get (in acrobat) clipped lines so this avoids that problem ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
