[NTG-context] Re: multipage metapost output from ConTeXt

[Mikael Sundqvist <mickep@gmail.com>]

Hi Emanuel,

I am not sure I understand your question, and since you use fonts that
i do not have, I cannot test your example as is. But, maybe, if you
want to redraw a picture, you can do

addto currentpicture also p1;

where you want it.

/Mikael

PS For the text thing, I did not get it. Could one have a _very
simple_ example showing only that problem and no other problem?

This overwriting happens only for the first textext() which occurs inside the for k=1 endfor loop. All other textext() inside the for k=1 endfor loop are not drawn at all. If the line  « draw textext("T="&decimal(currentime)) scaled 2 shifted(0,2in) withcolor magenta ; » is commented out, the first textext() inside the for k=1 endfor loop is not drawn neither. It must be an issue with textext(), because when I replace textext() by lmt_outline[], the text is drawn.
