wrong positioning of MP graphic in layer
Dear list, I have the following sample: \definelayer[wrongpositioned][x=0mm, y=0mm, hoffset=0mm, voffset=48mm, state=start] \setuplayer[wrongpositioned]{\startMPcode draw (0mm,0mm)--(8mm,0mm)--(8mm,38mm)--(14mm,38mm) ; \stopMPcode} \setupbackgrounds[page][background={wrongpositioned}] \starttext \input knuth \stoptext No matter what x, y, hoffset, voffset, location or corner, the MP graphic is located where the page margins start. Sorry for the so basic question, but what is wrong there? Besides that, I don’t understand how positioning in layers work. I have read the wiki, but I don’t get it (geometry isn’t my strength). x, y, hoffset and voffset are fine. But location and corner are mysterious to me. Changing them gave me no clue of what they are. The four mentioned options set a point in the paper. The corner could be the point of the graphic or text that would be set in the previously defined point in the paper. Well, if this isn’t wrong, what can location be? Sorry, I know it‘s my lack of geometrical knowledge. Could anyone be so kind to explain me what location and corner mean in layers? Many thanks for your help, Pablo -- http://www.ousia.tk

Dear list,
I have the following sample:
\definelayer[wrongpositioned][x=0mm, y=0mm, hoffset=0mm, voffset=48mm, state=start] \setuplayer[wrongpositioned]{\startMPcode draw (0mm,0mm)--(8mm,0mm)--(8mm,38mm)--(14mm,38mm) ; \stopMPcode} \setupbackgrounds[page][background={wrongpositioned}] \starttext \input knuth \stoptext
No matter what x, y, hoffset, voffset, location or corner, the MP graphic is located where the page margins start.

Many thanks for your help,
You can start from here \setuppapersize[A4][A3] \setuplayout[location=middle] \showframe %showlayout \definelayer[Page] \setuplayer[Page][width=\paperwidth,height=\paperheight] \setlayer[Page]{\startMPcode draw (0mm,0mm)--(PaperWidth,PaperHeight) withpen pencircle scaled 2pt withcolor red; draw (0mm,PaperHeight)--(PaperWidth,0mm) withpen pencircle scaled 2pt withcolor blue; \stopMPcode} \setupbackgrounds[page][background={Page}] \starttext \input knuth \stoptext See also http://wiki.contextgarden.net/Layers -- luigi

Many thanks for your reply, Luigi. I need to insist on this sample, because the layer doesn’t behave as such: \definelayer[wrongpositioned][x=5000cm, y=5000cm, state=start] \setuplayer[wrongpositioned]{\startMPcode draw (0mm,0mm)--(8mm,0mm)--(8mm,38mm)--(14mm,38mm) ; \stopMPcode} \setupbackgrounds[page][background={wrongpositioned}] \starttext \input knuth \stoptext x and y are outside the page in the layer definition (50 meters). It should be a stupid error, but I cannot say which one. It is a line that I need for my work.

Many thanks for this excellent example. Playing with it is the best way to learn. Thanks again for your help, Pablo -- http://www.ousia.tk

Exactly my fault, Hans, Totally overseen. Many thanks for your help, Pablo -- http://www.ousia.tk

I don't understand what exactly you need, but I hope this can help you. \showlayout \showframe \definelayer[wrongpositioned] \setuplayer[wrongpositioned][x=\backspace, y=\dimexpr \topspace+\headerheight\relax, state=start] \setlayer[wrongpositioned]{\startMPcode draw (0mm,0mm)--(TextWidth,0mm)--(TextWidth,TextHeight)--(0mm,TextHeight) -- cycle withpen pencircle scaled 2 withcolor red; drawarrow (0mm,0mm) -- (TextWidth,TextHeight) withpen pencircle scaled 2 withcolor blue; drawarrow (0mm,TextHeight) -- (TextWidth,0mm) withpen pencircle scaled 2 withcolor black; fill (0mm,0mm) -- (0mm,-FooterHeight) -- (TextWidth,-FooterHeight) -- (TextWidth,0mm) -- cycle withcolor blue; \stopMPcode} \setupbackgrounds[page][background={wrongpositioned}] \starttext \input knuth \stoptext -- luigi

Many thanks for your reply, Luigi. As Hans pointed out, I wrote \setuplayer instead of \setuplayer. As weird as it sounds, yesterday I used my first layers ever (copied from the wiki) and only in this one I typed \setuplayer instead of \setlayer. Well, it seems that I shouldn’t be sleepy when writing layers ;-). Many thanks for your help again, Pablo -- http://www.ousia.tk
