header misaligned and columns problem

header misaligned and columns problem

[Horacio Suarez]

[-- Attachment #1: Type: text/plain, Size: 899 bytes --]

Hello

This is my page:

\definepapersize[argento][width=20cm,height=28cm]
\setuppapersize[argento][A3]
\setuppagenumbering[alternative=doublesided,location=]
\setuplayout[location=middle,marking=on,textwidth=150mm]

And everithig is fine, but headers are not aligned with text.

Also, I use 2 columns in most of the book, but 4 chapters uses 3 columns.

I use

\startcolumns[n=2, balance=yes,distance=8mm]

or

\startcolumns[n=3, balance=yes,distance=5mm]

In two columns is ok, but in 3 columns, all the 3 columns don´t fit the 
whole textwidth, I mean, the sum of the 3 columns width plus the 2 
intercolumns space are less (about 1cm) than 150mm, as setuplayout says.

Thankyou very much.

So instead of specifying the textwidth, specify the backspace and 
cutspace and let context figure out the textwidth...

\setuplayout
   [width=middle,
    location=middle,
    backspace=2.5cm,
    cutspace=2.5cm,
    marking=on]

The following works fine for me....

\definepapersize[argento][width=20cm,height=28cm]
\setuppapersize[argento][A3]
\setuppagenumbering[alternative=doublesided,location=]
\setuplayout
   [width=middle,
    location=middle,
    backspace=2.5cm,
    cutspace=2.5cm,
    marking=on]

\showframe
\setupheadertexts[chapter][pagenumber]

\starttext

\chapter{Two Columns}
\startcolumns[n=2, balance=yes,distance=8mm]
\dorecurse{6}{\input knuth \endgraf}
\stopcolumns

\chapter{Three Columns}
\startcolumns[n=3, balance=yes,distance=5mm]
\dorecurse{6}{\input knuth \endgraf}
\stopcolumns

\stoptext
