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?
harmless ... it prevents clipping of lines
\setbox0\hbox{\useMPgraphic{foo}}
\the\wd0 \the\dimexpr2in\relax
\box0
the real dimensions and positioning is ok

mh, you mean if something is \framed (with default frame settings)?

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.

[NTG-context] beta: figure boundingbox
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?
