Am endeavouring to explore Wolfgang's very 'elegant' solution to this
facing page challenge. The exploration has included a look at
base/mkxl/page-inj.mklx (thanks Sreeram for reminding me of this)
where I see immediately that the approach is experimental and where it
says also that 'probably more alternatives will be added'. I wonder if
that last phrase also includes the ability to manipulate the image(s)
either generally or in individual cases?
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.
\definepageinjectionalternative
[chapter:image]
[renderingsetup=pageinjection:chapter:image]
\startsetups [pageinjection:chapter:image]
\centerbox{\externalfigure[\dummyparameter{name}]}
\stopsetups
\definepageinjection
[chapter:start]
[empty]
[page=left]
\definepageinjection
[chapter:insert]
[previouspage]
[alternative=chapter:image,
offset=1cm,
pagestate=stop]
\setuphead
[chapter]
[beforesection={\pageinjection[chapter:start]},
insidesection={\pageinjection[chapter:insert][name={chapter-\namedheadnumber{chapter}}]}]
\setuppagenumbering
[alternative=doublesided]
\setupexternalfigures
[location=default]
\useexternalfigure [chapter-1] [mill] [factor=max]
\useexternalfigure [chapter-2] [hacker] [orientation=90,scale=2000]
\useexternalfigure [chapter-3] [cow] [orientation=90,height=\framedwidth]
\starttext
\startchapter [title={Mill}]
\dorecurse{7}{\samplefile{lorem}}
\stopchapter
\startchapter [title={Hacker}]
\dorecurse{11}{\samplefile{lorem}}
\stopchapter
\startchapter [title={cow}]
\dorecurse{7}{\samplefile{lorem}}
\stopchapter
\stoptext
