issue with layers and layouts

issue with layers and layouts

[Pablo Rodriguez]

Dear list,

I have the following sample and two issues that I must solve:

\showframe\setuplayout[margin=20mm, width=fit, topspace=45mm,
bottomspace=25mm,
height=fit]
\definelayout[first][topspace=70mm, bottomspace=30mm]
\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{40}{\input knuth\par}
\stoptext

First, the layout is right on the first two pages, but it is wrong from
page three. The text doesn’t reach the bottom frame.

I have the info on multiple layers from the wiki (it isn’t a complete
example, though). After Wolfgang’s reply last Friday, I spend hours
searching on the mailing list trying to find relevant information to
know what I was doing wrong.

If this isn’t a bug, what am I missing here?

My second question is about the layer: is there no way to force the text
to avoid it as if it were a float?

Many thanks for your help,


Pablo

Many thanks for your reply, Luigi.

If I don’t get it wrong, if I define a layout for the first page, I have
to define it for even and odd pages, haven’t I?.

I want the text flow to avoid the layer "avoidasfloat" as it avoids the
figures.

\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{40}{\input knuth\placefigure[right]{}{}\par}
\stoptext

Layer has text inside in the sample above. I’d like to have it as a float.

Many thanks for your help,


Pablo

You can use positioned layers (mentioned in the metafun manual but currently broken in MkIV)
but you have to place the layer with a float to reserve the necessary space.


% engine=pdftex

\definelayer[avoidasfloat][position=yes]

\setupbackgrounds[page][background=avoidasfloat]

\starttext

\placefigure[right,none]{}{\setlayer[avoidasfloat]{\startMPcode draw unitsquare scaled 4cm ; \stopMPcode}}
\input knuth

\stoptext

Many thanks for your reply, Wolfgang.

Is there no way to place that layer exactly 8mm from left page border
and 110mm from top page border?

I really need the layer in that position (otherwise it doesn’t make sense).

Many thanks for your help,


Pablo

Remove “position=yes” when you want the layer on a certain position on the page but don’t
expect the text to flow around the layer.

Many thanks for your reply, Wolfgang.

I’m afraid that I need the layer on that position and text flowing
around the layer.

Is there no way to do place a MP graphic on a certain position and make
the text flow around it?

Sorry for insisting, but it surprises me that such a basic need seems
impossible with ConTeXt.

Many thanks for your help,


Pablo
