Metapost problems

Metapost problems

[emmanuel.rialland]

Hi,

I am trying to insert the same picture in a text at different places and in
different sizes.

The logo looks like a bicolor square with white text on top of it.
After many errands, I wrote the following so that I can size as needed:

\def\Logo#1%
  {\startMPgraphic
     % Top rectangle
     drawfill (0,0)--(2cm,0)--(2cm,1cm)--(0,1cm)--cycle with color blue ;
     % Bottom black rectangle
     drawfill (0,0)--(2cm,0)--(2cm,-1cm)--(0,-1cm)--cycle with color black
;
     % White Text
     draw btex \bf AB etex withcolor white ;
     % resize to size
     currentpicture := currentpicture scaled #1 ;
   \stopMPgraphic
   \loadcurrentMPgraphic
   \placeMPgraphic}

All I get is a frame with "undefined" written in it. Any clues?


I also try to have draft written in the right margin. I copied the text
showed p156 of the Metafun manual (the second example from the top). Never
had any success. Is there anything I am missing?



Now weirder (to me at least). A bit further in my doc, I have a chart
created with the chart module.
I had to comment out the chart code. If I don't, all the logos and all the
right margins (where I would like to see DRAFT) are replaced by the chart.
And at the location where the chart is included, there is no chart (more
precisely, there is no boxes and arrows but the labels are still there,
scattered around over the text as an overlay).

I am using teXExec 3.1 that comes with Cygwin.


Any help is welcome.

Thanks in advance,


Emmanuel

I've never seen this command before. Yet another MP environment :)

try
\protectbufferstrue

at the beginning of your document and please report the result. Also
please make sure that you have cont-sys.tex in your tex tree somewhere.

  Brakhane (or sth. similar) in texexec. ]

What happened? Did you get the same error?

That is weired, but hard to tell why. Please post a minimal example
that shows your problem. And please make sure that it is a full
working example! Including \starttext... \stoptext and other
necessary commands. But not more than this. Thank you.

That's a real low level one, not reallu meant for the user level,

\startMPcode
  ...
\stopMPcode

is the way to go here

Re: Metapost problems

[emmanuel.rialland]

I am happy to report some progress thanks to your help.

reinstalled the context package;
\protectbufferstrue is full of black magic;
noticed that there shouldn't be any white space between with and color;

Making more changes on the logo definition. Not quite there yet, but on the
way.

All in all getting better. Even the chart has gone back where it should be
(I have no idea what the problem is/was).

The draft still doesn't appear.

Another question:
- how to change the font of the logo text?

Thanks,


Emmanuel

How should we know what is going wrong?

\startMPenvironment[+]

[fontswitch]

\stopMPenvironment

([+] is for setup of MP *and* TeX text, not needed for MP only)
