Hi all,
i have two questions regarding the use of layers.
-- Is there an easy way to position a layer in the middle of the page.
My intent is to position some kind of graphic/picture there.
I usually try to wrap the picture in a hbox to \paperwidth {\hfil
\externalfigure{} \hfil} and then
wrapping the hbox in a vbox
-- Is there a better way to achieve this?
-- How to do that with layers?
-- Is it possible to define and position layers in one Macro. I have
something like the following
in mind (untested):
\define[1]\MLayer{
\definelayer[#1]
\setlayer[#1][state=start]{\externalfigure[#1]}
}
My experience so far is, that it's necessary for a layer to appear that
it is listed in pagebackgrounds
ist this true? With this it seems, that a macro like that above is
impossible, true?
\define[1]\MLayer
{\definelayer[#1]%
\expandparameters\setupbackgrounds[page][background={\currentvalue,#1}]%
\setlayerframed[#1][width=\paperwidth,height=\paperheight,frame=off,align={middle,middle}]{\externalfigure[#1]}}
