Some question regarding Layers
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? thanks in advance for your help Erik

\define[1]\MLayer {\definelayer[#1]% \expandparameters\setupbackgrounds[page][background={\currentvalue,#1}]% \setlayerframed[#1][width=\paperwidth,height=\paperheight,frame=off,align={middle,middle}]{\externalfigure[#1]}} Wolfgang
Hi all, please have a look at the attached example. Is there a (not manually) possibility to reduce the space of two consecutive headers? Another situation is if a header with ‘before=,’ is followed by an environment with 'before=\blank’ … \setupdelimitedtext[blockquote][before=\blank,after=\blank] \setuphead[subject][after=,style=\bfa] \starttext \subject{No space after the header} \input tufte \subject{Space from the \tex{blockquote}-environment} % \vskip-\lineheight \startblockquote \input tufte \stopblockquote \input tufte \startblockquote \input tufte \stopblockquote \startcolumns \section{Section} \input tufte \par \subsection{Subsection} \input tufte \par \column \section{Section} % \vskip-1.25\lineheight \subsection{Subsection} \input tufte \par \input tufte \par \stopcolumns \stoptext Thanks in advance Andreas

\setupdelimitedtext[blockquote][before=\blank,after=\blank]
\setupdelimitedtext[...][spacebefore=default,spaceafter=default] you can now use before/after for different settings
\setuphead[subject][after=,style=\bfa]
\starttext \subject{No space after the header}
\input tufte
interesting because it works in MkII when i add \setupinterlinespace[...] to the preamble
\subject{Space from the \tex{blockquote}-environment} % \vskip-\lineheight
\startblockquote \input tufte \stopblockquote
\input tufte
\startblockquote \input tufte \stopblockquote
\startcolumns \section{Section} \input tufte \par \subsection{Subsection} \input tufte \par \column \section{Section} % \vskip-1.25\lineheight \subsection{Subsection} \input tufte \par \input tufte \par \stopcolumns
\stoptext

Hello Wolfgang, thanks for the hint, but I don’t get it. How can I bind a signal to a heading? If I understand right a signal is a tag that can be attached to a macro …? So I’ve tried the following: \newsignal\SpaceAfterSection \def\TestSpace {\ifdim\lastskip=\SpaceAfterSection \blank[nowhite] \else \blank[2*big]\fi} \setuphead[section] [after=\SpaceAfterSection] \setuphead[subsection] [before=\TestSpace] \starttext % \showgrid \startcolumns \section{Section} \input tufte \par \subsection{Subsection} \input tufte \par \column \section{Section} \subsection{Subsection} \input tufte \par \input tufte \par \stopcolumns \stoptext I appreciate your help! Andreas PS. I use only MkIV

A signal is a (very small) vertical or horizontal skip, to use it you need \vskip or \hskip. \setuphead[section][after=\vskip\SpaceAfterSection] Wolfgang

Ah, I see, that did the trick. Thanks you very much! Andreas
