Donno (as I never used this method). Better use

'setbounds currentpicture to' ..
.. 'unitsquare xyscaled(w,h);'
.. 'OverlayBox;'
.. ;

at the end of your graphic. This simply sets the bounding box of you
graphic and has no unwanted side effects.

[NTG-context] MetaPost visibly drawing at 0pt

2011-09-19 Thread Meer, H. van der
I used to put an invisible frame around figures in MetaPost by setting a pen 
scaled at 0pt. That left no trace, but defined the area.
However I (now) see a thin line drawn by code:

pickup pencircle scaled 0pt;
draw origin--(w,h);

Did I always mis this or has something changed? For example a roundoff away 
from zero in MetaPost?
By the way I am typesetting through ConTeXT with \startMPpage … \stopMPpage.
