Hi all, I need to use the background mechanism to draw a thicker line in a bTABLE...eTABLE setup together with MKII. It looks like that there is a bug somewhere in this. I am unable to draw the line at the top of the cell. However it is possible to draw a diagonal through the cel. I think that the problem is related to the background mechanism in general, because the problem is also present when using the background mechanism in framed. The behavior is identical in MKII en MKIV. I updated this morning to the latest version of Context, the bug is there as it was in a version ca 1 month old. Please refer to the attached test file. Using: This is pdfTeX, Version 3.1415926-1.40.11 (TeX Live 2010) ConTeXt ver: 2010.08.04 00:37 MKII fmt: 2010.8.4 int: english/english Kind regards Willi

Hello Willi, Here some workaround: \startuniqueMPgraphic{Topline} path p,q; p := unitsquare xscaled \overlaywidth yscaled \overlayheight; draw urcorner p -- ulcorner p withpen pencircle scaled 2pt; draw lrcorner p -- lrcorner p withpen pencircle scaled 0pt; \stopuniqueMPgraphic Cheers, Peter -- Contact information: http://pmrb.free.fr/contact/
Hi Peter, thanks for this rapid reply! Though not nice, it works! Willi On 4 Aug 2010, at 09:32, Peter Münster wrote:

No bug, only the bounding box. The relative position of a graphic does not count any longer, if the graphic leaves MP. For example: drawing a fullcircle/unitcircle results in the same graphic, although they have a different center point. Only the final boundingbox is counting here (equal in this case). In your example the boundingbox has the size (OverlayWidth,2pt) or (OverlayWidth+2pt,2p) if you ignore the linewidth. So you need a manual boundingbox setup, as in the attached example. The Topline does not cross the borders of the OverlayBox (donno if this is wanted, but easy to change). Best wishes, Peter
Hello Peter, thanks for your explanation. Hm, that also makes clear why the diagonal works without setting the bounding box. Willi On 4 Aug 2010, at 09:45, Peter Rolf wrote:
