metapost and luatex (or xetex)

metapost and luatex (or xetex)

[Diego Depaoli]

Hi all,
from metafun manual, page 157, I took this example

\startuniqueMPgraphic{copyright}
picture p ; p := btex COPYRIGHT etex rotated 90 ;
setbounds p to boundingbox p enlarged 1pt ;
draw p withcolor .8white ;
xyscale_currentpicture(\the\leftmarginwidth,\the\textheight) ;
\stopuniqueMPgraphic
\setuptexttexts [margin] [] [\uniqueMPgraphic{copyright}]
\starttext
\input knuth
\stoptext

but compiling it I get some trouble

texexec --pdf works as expected
texexec --lua drops colors (COPYRIGHT is black)
texexec --xtx gives no output (linux and FreeBSD)

All normal?

Regards

is ok, use btex color[white]{COPYRIGHT} etex instead

(no colorization of pictures with text in mkiv)

But that doesn't work in mkii then unless some other "hacks" are added.
(I know, mkii and mkiv are not compatible, but there are no obvious
limitations why they could not work in the same way.)

> (no colorization of pictures with text in mkiv)

(In the particular case of gnuplot, I have no idea how to deal with
that situation without a bunch of extra work since it's not so simple
to convert some color from metapost variable into one that ConTeXt
accepts in \color[...]. I have \chardef\TeXtextcolormode\zerocount in
mkii, but I still consider it ugly.)

In the case of XeTeX: no, it's not normal. If you add
\loadmapfile[lm-ec.map] this solves the problem, but if I was on your
place, I would use \sometxt{COPYRIGHT} instead of btex COPYRIGHT etex.

Loading map files has been removed from XeTeX a while ago. Maybe lm-ec
should be added back for such cases? (I remember some problems with
btex etex in past after map files have been removed, but I don't
remember solving anything at that time.)

actually there are ...

in mkii btex/etex pipes to an external instance of tex and then converts 
the dvi to mp code; so, there we have a mp picture that we can color as 
such (color info done in the tex job is lost)

in mkiv btex/etex pipes to the current tex instance and mp never sees 
the result, only dimensions, and as such there is nothing to color; if i 
construct a more comples model for extensions i can make that work, but 
i'd rather wait for mplib to be extended with multiple pre/postscripts 
(is on the agenda but with low priority)

well, just define a color on the spot ..

{\definecolor[temp][specs]\color[temp]text}

indeed (althouh in mkiv they are the same .. btex/etex is converted to 
textext on the fly)

\sometxt works nice.

Many thanks.

(prepend \setupcolors[state=start])

btex \color[gray]{COPYRIGHT} etex %% gray
btex \color[white]{COPYRIGHT} etex %% white (hard to see with a white
background)
