The funny fractions -%D were introduced when we went from fixed dimensions to relative ones. Since -%D \CONTEXT\ is a dutch package, the dimensions are based on the metric system. The -%D asymmetrical layout is kind of handy for short quick||and||dirty stapled -%D documents. -%D -%D Although valid, it is not a real good idea to use dimensions based on the \type -%D {em} unit. First of all, since there are no fonts loaded yet, this dimension -%D makes no sense, and second, you would loose track of values, since they could -%D change while going to a new page, depending on the current font setting. - -\setuplayout - [ \c!topspace=.08417508418\paperheight, % 2.5cm - \c!top=\zeropoint, - \c!topdistance=\zeropoint, - \c!header=.06734006734\paperheight, % 2.0cm - \c!headerdistance=\zeropoint, - \c!height=.84175084175\paperheight, % 25.0cm - \c!footerdistance=\layoutparameter\c!headerdistance, - \c!footer=.06734006734\paperheight, % 2.0cm - \c!bottomdistance=\layoutparameter\c!topdistance, - \c!bottom=\zeropoint, - \c!backspace=.11904761905\paperwidth, % 2.5cm - \c!edge=\zeropoint, - \c!edgedistance=\layoutparameter\c!margindistance, - \c!margin=.12649983170\paperwidth, % snijwit-2*afstand - \c!margindistance=.02008341748\paperwidth, % 12.0pt - \c!leftedge=\layoutparameter\c!edge, - \c!leftedgedistance=\layoutparameter\c!edgedistance, - \c!leftmargin=\layoutparameter\c!margin, - \c!leftmargindistance=\layoutparameter\c!margindistance, - \c!width=.71428571429\paperwidth, % 15.0cm \dimexpr\ - \c!rightmargindistance=\layoutparameter\c!margindistance, - \c!rightmargin=\layoutparameter\c!margin, - \c!rightedgedistance=\layoutparameter\c!edgedistance, - \c!rightedge=\layoutparameter\c!edge, - \c!veroffset=\zeropoint, - \c!bottomspace=\zeropoint, - \c!horoffset=\zeropoint, - \c!cutspace=\zeropoint, - \c!textwidth=, % dangerous option -> centered / local - \c!textmargin=, % dangerous option -> both sides - \c!textdistance=\zeropoint, % shift down on grid - \c!style=, - \c!color=, - \c!marking=\v!off, - \c!location=,% \v!singlesided, but unset is signal (no other default, spoils arrange) - \c!state=\v!start, - \c!scale=1, - \c!sx=1, - \c!sy=1, - \c!nx=1, - \c!ny=1, - \c!dx=\zeropoint, - \c!dy=\zeropoint, - \c!grid=\v!no, - \c!direction=\v!normal, - \c!preset=, - \c!setups=\systemsetupsprefix\s!default, - \c!clipoffset=\zeropoint, - \c!lines=0, - \c!paper=, % for foxet - \c!page=, % for foxet - \c!columns=\plusone, - \c!columndistance=\zeropoint] - -%D First we define a whole range of (DIN) papersizes, of which the A-series makes -%D most sense.
