… and use \setlayer. Thanks Wolfgang, I think I’m piecing together how layers, 
backgrounds and the pagebreak mechanism fit together.

Folks,

I want \startfrontmatter to trigger a background image, but I can only 
get this to appear if I use page=yes (see example below).


However, I don’t want any page break between the front-matter and 
body-matter. If I use page=no (as in the line commented out) this page 
break disappears — but so does the background image!


How can I get the background behind the page where the front-matter 
text appears, but with no page break before the body-matter?

Set the page background outside of the sectionblock.

\setupexternalfigures[location=default]

\definelayer[frontbackground]

\setupbackgrounds[page][background=frontbackground]

\startsectionblockenvironment[frontpart]

\setlayer[frontbackground]{\externalfigure[mill][width=\paperwidth,height=\paperheight]}

\stopsectionblockenvironment

\setupsectionblock[frontpart][page=no]
\setupsectionblock[bodypart][page=no]

\starttext

\startfrontmatter
Should be on a first page
\stopfrontmatter

\startbodymatter
Should follow frontmatter with no page break
\stopbodymatter

\stoptext

Wolfgang

[NTG-context] \setupsectionblock and \setupbackgrounds page-break problem

[Robin.Kirkham]

Folks,

I want \startfrontmatter to trigger a background image, but I can only get this 
to appear if I use page=yes (see example below).

However, I don’t want any page break between the front-matter and body-matter. 
If I use page=no (as in the line commented out) this page break disappears — 
but so does the background image!

How can I get the background behind the page where the front-matter text 
appears, but with no page break before the body-matter?
