layer documentation?

layer documentation?

[Patrick Gundlach]

Hello Hans and others,

is there any layer documentation out there that I have missed?

I found some fragments in the metafun manual, the details.pdf and
(well, of course!) the source.

Where should the layers be hooked in?

If I say \setupbackgrounds[text][text][background=relpos], the layer
relpos gets repeated; if I use \setupbackgrounds[page][..], the layer
won't be repeated, even if I say
\setupbackgrounds[page][background=..,state=repeat]. (Yes, I know
that I can use \setuplayer[...][state=repeat]; I try to understand
what is going on.)

So should I always use the [page] background to anchor the layer?

Patrick

   [text][text] and [page] are repeated indeed

others are if \setupbackgrounds[state=repeat]

another option is:

   \checktextbackgrounds

and put things in the predefined text-2,text-2,text+1,text+2 layers

(studying core-box may shed some light on this)

[page] is not repeated here:

%output=pdf
\showframe

\setupbackgrounds[page][background=abspos]
\setupbackgrounds[text][text][background=relpos]

\definelayer[abspos][option=test,
        width=\paperwidth,
        height=\paperheight,
         ]

\definelayer[relpos][option=test,position=yes]

\starttext 
\input tufte
\setlayer[abspos][x=1cm,y=1cm]{\bfd It Works!}
\setlayer[relpos][offset=1cm]{really?}
\input tufte

\page

\input tufte
\setlayer[relpos][hoffset=1cm,voffset=-1cm]{What does it look like?}
\input tufte
\page
\input tufte

\stoptext


layer relpos gets repeated, layer abspos not.

sorry: can you try just one [text]

OK, I did and found out that here none of those two are
repeated. Even with state=repeat in \setupbackgrounds:

%output=pdf
\setupbackgrounds[page][background=abspos,state=repeat]
\setupbackgrounds[text][background=relpos,state=repeat]

\definelayer[abspos][option=test,
        width=\paperwidth,
        height=\paperheight,
         ]

\definelayer[relpos][option=test,position=yes]

\starttext 
\input tufte
\setlayer[abspos][x=1cm,y=1cm]{\bfd It Works!}
\setlayer[relpos][offset=1cm]{really?}
\input tufte

\page

\input tufte
\setlayer[relpos][hoffset=1cm,voffset=-1cm]{What does it look like?}
\input tufte
\page
\input tufte

\stoptext
