bug in multiple layouts?

bug in multiple layouts?

[Pablo Rodriguez]

Dear list,

I have a sample with multiple layouts:

\showframe
\setuppagenumbering[alternative=doublesided, location=]
\setuplayout[margin=20mm, width=fit, topspace=45mm, bottomspace=25mm,
height=fit]
\definelayout[shorter][backspace=80mm, cutspace=20mm, topspace=110mm,
bottomspace=30mm]
\setuplayout[shorter]
\setuplayout[reset]
\definelayout[1][shorter]
\definelayout[2-last][reset]
\starttext
\dorecurse{20}{\input knuth\par}
\stoptext

I found two issues: the first lines on the second page have the margin
from previous page, and from the third page text doesn’t reach the page
bottom.

Am I missing something or have I found a bug?

Many thanks for your help,


Pablo

1. reset is a keyword for \setuplayout (single argument version) and not a name for a predefined layout

2. You can’t define layouts for page ranges (e.g. 2-last), only page numbers (e.g. 2,5, or -3), names (e.g. mylayout) and keywords (e.g. first, last, odd and even) are possible.

3. The width of a paragraph is fixed and tex doesn’t changed the width of the part which is moved to the next page (there are a fix tricks to work around this limitation but they work only when you have a text only document).

4. TeX has its limitations and you have to live with them, with LuaTeX there are ways to get rid of a few of them but it takes time to write the necessary code

Many thanks for your reply, Wolfgang.

I want to have a different top and bottom space only for the first page.
From I what I understand, here is a new sample (that doesn’t work):

\showframe
\setuppagenumbering[alternative=doublesided, location=]
\setuplayout[margin=20mm, width=fit, topspace=45mm, bottomspace=25mm,
height=fit]
\definelayout[first][topspace=110mm, bottomspace=30mm]
\starttext
\dorecurse{20}{\input knuth\par}
\stoptext

I define a the standard layout, a layout for the first page, but I don’t
know why the text doesn’t fill the full text area in pages other than
the first.

As a workaround: is it possible that the text flow avoids layers as if
it were floats?

What I mean is that in the following sample the text flow avoids the
rectangle:

\definelayer[avoidasfloat][x=0mm, y=0mm, hoffset=8mm, voffset=101mm,
location={right,bottom}, state=start]
\setlayer[avoidasfloat]{\startMPcode
draw (0mm,0mm)--(55mm,0mm) ;
draw (0mm,0mm)--(0mm,-86mm) ;
draw (0mm,-86mm)--(55mm,-86mm) ;
draw (55mm,-86mm)--(55mm,0mm) ;
\stopMPcode
}
\setupbackgrounds[page][background={avoidasfloat}]
\starttext
\dorecurse{4}{\input knuth\par}
\stoptext

How could this be done?

Many thanks for your help,


Pablo
