Irregularity in a topspace a bottomspace?
Hi all. I was surprised that when I set up (in the MKII and MKIV too) topspace parameter to a nonzero value and the value of the bottomspace parameter to zero value, then the size of bottomspace is the same as topspace size. On the other side, if I set topspace to zero value and the bottomspace to nonzero value, ConTeXt behaves as I expected. Is this a normal behavior ConTeXt? Ie. when bottomspace is zero, then the paper has only the tops and not bottoms? Thanx Jaroslav My minimal example (watch showlayout): 1. topspace is nonzero, bottomspace is zero value: \setuplayout[ backspace=0cm, leftmargin=0cm, width=fit, rightmargin=0cm, cutspace=0cm, topspace=2cm, headerdistance=0cm, header=0cm, height=fit, footerdistance=0cm, footer=0cm, bottomspace=0cm ] \starttext \showlayout \input tufte \stoptext 2. topspace is nonzero, bottomspace is nonzero value too: \setuplayout[ backspace=0cm, leftmargin=0cm, width=fit, rightmargin=0cm, cutspace=0cm, topspace=2cm, headerdistance=0cm, header=0cm, height=fit, footerdistance=0cm, footer=0cm, bottomspace=1cm ] \starttext \showlayout \input tufte \stoptext 3. topspace is zero, bottomspace is nonzero value: \setuplayout[ backspace=0cm, leftmargin=0cm, width=fit, rightmargin=0cm, cutspace=0cm, topspace=0cm, headerdistance=0cm, header=0cm, height=fit, footerdistance=0cm, footer=0cm, bottomspace=1cm ] \starttext \showlayout \input tufte \stoptext

When you set 'width=fit' or 'width=middle' context looks at the bottomspace value and if the bottomspace height is 0pt it assign to the bottomspace the height of the topspace. The only thing you can do it to assign a domension ti height, e.g. 'height=15cm'. @Hans: How about a 'height=auto' key which calculates the textheight like 'height=middle' but doen't change the bottomspace value even if the value is 0pt?

Ok. Thanx. I see that you are due my ignorance revealed a problem that I did not report :-) Jaroslav Dne 11.6.2010 11:50, Wolfgang Schuster napsal(a):
