[Colored text's background, which the more "lcd-mkiv"?;
plus: Metapost variable "text" with "\definetextbackground";
plus: {\input ward}]
Hi list,
What would be the best, also the more up to date, way to put colored
background behind text, that could cross page boundaries.
I have found three ways of doing this: I would like to know which is
best practice, and also the more "lua context document" fashion.
1- Using "\startbar[underbar] \input zapf \stopbar" as described p. 39
of "hybrid.pdf".
2- Using "\startMPpositionmethod{mpos:placeholder}", found in
http://tex.stackexchange.com/questions/125162/rounded-box-around-placeholder-text-that-supports-line-breaking/125323
(Thanks to Aditya).
A bit tricky, but perhaps the more versatile or universal?
3- Start with: "\definetextbackground" (same ref. as previous).
%%%%%%%%%%%%%
% About the third one I have had some difficulties, that might be
thought of as a bug.
% You might want and try the following example: it doesn't work if you
have a MetaPost variable
% whose name is "text".
\starttext
\startMPcode
% numeric text; %% Try and uncomment this line
drawarrow (0,0)--(3cm,1cm);
\stopMPcode
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\definecolor [lightblue] [r=0.5, g=0.5, b=1]
\definetextbackground
[placeholder]
[
location=text,
background=color,
backgroundcolor=lightblue,
frame=on,
corner=round,
radius=0.8\lineheight,
]
\placeholder{\input ward }
% \placeholder{\input ward} %% Try and uncomment this line
\stoptext
% Local Variables:
% mode: context
% coding: utf-8
% End:
Regards,
Chris
