This too seems to be wrong. It should be OuterMarginWidth but it is only 
correctly positioned for InnerMarginWidth, indicating therefore that the 
distances were not updated (?).

[NTG-context] Double-sided documents with MetaFun's Field[Text][Text]

2022-02-06 Thread śrīrāma via ntg-context
Dear list,

I have a double-sided document in which I want to draw certain page 
backgrounds on the right (odd) and left (even) pages. Here is an example

%%% SOF
\setuppagenumbering[alternative=doublesided]
\setuplayout
[backspace=4cm,
leftmargin=4cm,
cutspace=2cm,
rightmargin=2cm,
leftmargindistance=0cm,
rightmargindistance=0cm,
header=2cm,
footer=2cm,
topspace=1cm,
bottomspace=1cm,
top=1cm,
bottom=1cm,
width=middle,
height=fit]

\startuseMPgraphic{page}
StartPage;
draw Area[Text][Text] 
shifted (InnerMarginWidth,BottomHeight+FooterHeight);
draw Field[Text][Text] withcolor blue;
StopPage;
\stopuseMPgraphic
\defineoverlay[page][\useMPgraphic{page}]
\setupbackgrounds[page][background=page]

\starttext
\dorecurse{10}{\input knuth \page}
\stoptext
%%% EOF

In the resulting PDF the Field[Text][Text] path is not positioned (/computed?) 
correctly, while the manually positioned Area[Text][Text] path is as expected. 
So, it seems that the margin widths and other distance are updated for each 
odd, even page but Field[Text][Text] is still wrong? The Field[Text][Text] 
path appears on every page as though it is on an odd (right) page.

Have I missed something?

Thanks,
śrīrāma (Sreeram)
