Re: [NTG-context] help with facing page image
Thanks Wolfgang. This version is the 'icing on the cake' I think, a
further refined version of the suggestion put forward by Sreeram.
Grateful as always,

Keep your expectations low. I wrote the code (with some changes from
Hans) to include full page images in novels and the code hasn't changed
much since 2013.
So, for example., say I need (and in fact I do!) to change some aspect
of individual images, e.g. I might want to scale=500, or fiddle with
width/height of a particular image. At the moment I cannot see a way
of doing this for each image. I wondered if the commented out setups
in the response to this question might be a clue, but so far haven't
been able to get that to have any effect.
You have to use a custom alternative (see below) to place the image on
the page because the default alternative scales the image to fit on the
available space. The best solution to change orientation, size etc. of
the included images is to use the \useexternalfigure command and make
all changes in the style file.

Re: [NTG-context] help with facing page image
Using your example, Sreeram, but adapting it to my own set of images
(which are not cows or spiders!) I can now see clearly how to make use
of all the essential information that had initially been provided by
Wolfgang, and also the important hint, which I had clumsily and
unsuccessfully been trying anyway before he offered it, from Aditya,
about passing key value parameters along the lines of Wolfgang's 'name
='. It simply did not occur to me to do this using 'factor= '. But there
was much more about the example I would not have worked out by myself as
well!
Thank you (all) for your patience.

Couldn't you just pass scale as a key-value parameter, similar to how `name` is
passed in Wolfgang's solution?

Appreciate your assistance. I'll do my best with what you offer here.
Of course, I've always said these images are at the beginning, not
"the end of their respective chapters" and I've already indicated how
the images are named, simply as Chapter1.jpg and so on, so I'll need
to work around these differences in your example. But with trial and
error, let's hope I get there!
The example below uses a different mechanism to add images at the
start of a chapter. In the example you have to pass the name of image
as userdata argument of \startchapter but in the commented \setuphead
setting you can see how this can be automated.

Re: [NTG-context] help with facing page image
Special thanks to Sreeram, Wolfgang, Bruce, Hraban for help with this
issue, ranging from the simplest 'manual' approach (Bruce) to one that I
must confess I could never have thought of using: definepageinjection
(Wolfgang). Needless to say, all contributions work, with a bit of
adjustment in each case for my particular situation.
The one common factor in all four contributions is the use of setups, so
a light has begun flashing for me: setups are such an important feature
of ConTeXt for solving many problems!
Thanks to all,

A simpler solution as you only have 10 chapters might be to 'manually' add the
facing page rather than fiddle with the definition of \startchapter.
For example:
\definestartstop [ChapterPreface]
[ before={\setups{ChapterPrefaceSetup}},
after={\page}
]
% which gives you the commands \startChapterPreface ... \stopChapterPreface
which I put immediately before \startchapter in the text.
% Then use a setup to prepare the page for your image (you may only need
\page[left] but also remember you need to stop page headers/footers etc from
the previous chapter)
\startsetups ChapterPrefaceSetup
\page[left]
\setupheader[state=empty]
% etc
\stopsetups
% If the page setup is complicated then you might need another setup to clean
it up afterwards. In this example there is just the "after=" in the definition.
% Now you can print your images by using:
\starttext
\startChapterPreface
\externalfigure[cow.pdf]
\stopChapterPreface
\startchapter[title={firstchapter}}
...
\stopchapter
\startChapterPreface
\externalfigure[another_cow.pdf]
\stopChapterPreface
\startchapter{title={second chapter}]
...
\stopchapter
\stoptext
Hope this helps.

Appreciate your assistance. I'll do my best with what you offer here.
Of course, I've always said these images are at the beginning, not

the images are named, simply as Chapter1.jpg and so on, so I'll need
to work around these differences in your example. But with trial and
error, let's hope I get there!
The example below uses a different mechanism to add images at the start
of a chapter. In the example you have to pass the name of image as
userdata argument of \startchapter but in the commented \setuphead
setting you can see how this can be automated.

% \definepageinjectionalternative

% \startsetups [pageinjection:chapter:image]
% \clip

\definepageinjection

\startchapter [title={Mill}] [image=mill]
\dorecurse{7}{\samplefile{lorem}}

\dorecurse{11}{\samplefile{lorem}}

Re: [NTG-context] help with facing page image
I can see how that works, Sreeram, especially the chapter:after to cope
with the chapters ending on an even page. Though I will have to try it
now on a copy of the real document to test it there.
All ten images are different, though, in my case (Chapter1.jpg,
Chapter2.jpg... Chapter10.jpg all in a pics directory, so I'd point
\setupexternalfigures to that). I wonder if there is a way to list them
so that they get called in order as chapters proceed. A kind of "if such

[NTG-context] help with facing page image
I wonder if someone can help me untangle the current little mess I seem
to be creating!
Author wants an image on facing page to each of 10 chapters in the
bodypart of the document. Assume that everything else is working
properly for this document (double-sided etc.), but other than before
chapter 1, I can't seem to get my facing page image to appear where it
should!
A question along these lines (but not quite the same) was asked back in
2019, so I started with what seemed to me to be the simplest response to
this question. Here is what I have to get the image before Chapter 1 in
bodymatter:
\startbodymatter
\definelayer[mylayer] % name of the layer
[x=0mm, y=0mm, % from upper left corner of paper
width=\paperwidth,height=\paperheight] % let the layer cover the full paper
\setlayer[mylayer]
[hoffset=2.5cm, voffset=3cm]
{\externalfigure[Chapter1.jpg][width=.9\textwidth]}
\doifoddpageelse
{}
{\pushbackground[page]
\setupbackgrounds[page]%[background=color,backgroundcolor=red]
[background=mylayer]
\page[empty]
\popbackground}
\startchapter[title={Prelude}] etc.
This correctly places the Chapter1.jpg on the facing page to Chapter 1.
My problem comes with Chapter 2, since Chapter 1 finishes on an even
page, and this means I would need a blank odd page to follow that so
that Chapter2.jpg (a different image to the first) can be on the verso
of that and the Chapter itself would then start on the odd page facing that.
I think the \doiffoddpageelse command above is only meant to work when a
chapter ends on an odd, not an even page, but I do not know what
alternative command to give.
Repeating the above set of commands prior to \startchapter for chapter 2
places the image, naturally enough, behind the last page of text for
Chapter 1, which is unacceptable, so I thought I could simply add a
blank page or two after the chapter and it would all fall into place. I
tried various ways of doing that (e.g. \page[+2], or using makeup
pages), and while I can add pages that way, I can't get the image to
appear.
No doubt the solution is simple enough. It might also lie in the
\setuphead[chapter] arrangement too. I've tried page=yes there, but to
no avail. I also tried \ startsetups[chapter:before] with the
pushbackground etc command and added that in with
before=\directsetup{chapter:before} as suggested in the wiki, but
couldn't get that to work either. By that stage I was so tangled up in
the problem I may not have been able to think straight :-). Somehow,
though, I think most of the elements are there.
Any help would be appreciated.
