Hi all,

in my document \startchapter and \starttitle starts a new chapter on the right (odd) page. So sometimes, there is a blank even page just before a new chapter.

I would like to manipulate this blank even page.

There are several things I would like to do, eg. having no headers and footers, setting the background color to a named color, placing an image or some graphics on the page.

Is there a way to define such a page, name it and call it in \startchapter so that it is placed on the left side.

See https://tex.stackexchange.com/q/457428/323

Thanks a lot, but I wasn't looking for a way to just delete page numbers but to style the empty page in arbitrary ways. Maybe it is better to do this manually. I would let chapter open on even pages too and just insert a styled page by hand. juh

Here is a example which shows how you can change the background color of a empty page before the chapter title. \setuppagenumbering   [alternative=doublesided] \startsetups [chapter:before]   \doifoddpageelse     {}     {\pushbackground[page]      \setupbackgrounds[page][background=color,backgroundcolor=black]      \page[empty,right]      \popbackground} \stopsetups \setuphead   [chapter]   [page=yes,    before=\directsetup{chapter:before}] \starttext \startchapter[title={Knuth}] \dorecurse{10}{\samplefile{knuth}} \stopchapter \startchapter[title={Zapf}] \dorecurse{10}{\samplefile{zapf}} \stopchapter \startchapter[title={Ward}] \dorecurse{10}{\samplefile{ward}} \stopchapter \stoptext Wolfgang

\startchapter[title={Zapf}] \dorecurse{10}{\samplefile{zapf}} \stopchapter

\startchapter[title={Ward}] \dorecurse{10}{\samplefile{ward}} \stopchapter

\stoptext

Thanks a lot Wolfgang!

This was just the thing I was looking for. These setups seems to be the golden bullet in ConTeXt but I often have difficulties to understand the mechanism.

If you mean the setups-environment with setups you’re wrong because this is only a alternative way to a command (e.g. \define\mycommand{...}). The main point is that you finish the page before the section title and check on the new page whether you’re on a odd or even numbered page. When the test tells you that you’re on a even numbered page you know there is a empty left page before the chapter which can be used to add something special. Below is a simplified example for the method. \starttext \dorecurse{10}{\samplefile{knuth}} \page \doifoddpageelse {} {\pushbackground[page] \setupbackgrounds[page][background=color,backgroundcolor=red] \page[empty] \popbackground} \dorecurse{10}{\samplefile{zapf}} \stoptext

I'll try to wikify this later this week.

The push-pop-background pair is mentionend in x-setups-overview together with some other push-pop-pairs or push single commands. Are they documented somewhere?

Most of these push/pop commands are used for internal stuff (or sometimes in styles) which means there is no documentation for them. The purpose of them is to store the state of a command (e.g. the page background) before you change its values, afterwards you can just revert back to the previously saved state. As these commands are no real environments they are listed as separate commands but it’s possible I will change this. Wolfgang

I wikified it here: https://wiki.contextgarden.net/Command/setuphead

Is there a way to suppress the context output? The output does not show the effect.

I patched your example a little so that it now does show the effect. Best wishes, Taco
