[NTG-context] Re: another itemize question

[Patrick Gundlach]

Hi Gary,

 Now back to our regularly scheduled thread...
 I'm reaching the conclusion that the behaviour I reported at the top of the
 thread is a bug.
 Is it?
 If so, is a workaround or fix possible?

We had almost the same thread in May(?) this year. I came to the
conclusion that I don't know how to solve this. IMO a real expert
should look into this.

[NTG-context] Re: Integrating Metapost

[Patrick Gundlach]

Andres Loeh [EMAIL PROTECTED] writes:

Hello Andres,

 This seems to be a very common problem. Isn't it possible
 to integrate a check into the metafun code so that a more
 helpful error message is produced in case of a format
 version mismatch?

That would be good. Just as an example, one can do this in LaTeX:

\NeedsTeXFormat{LaTeX2e}[1995/12/01]
(there are a few related commands)

so you can make sure to have LaTeX2e newer than the given date. 

But I don't know how to get the metafun format number. One can't pass
mpost variables back to TeX?

[NTG-context] Dithering (off-topic)

[Michal Kvasnicka]

Good evening.

I apologize to ask a little off-topic question, but I don't know where 
to ask (and it is closely related to TeX and PDF).

I typeset a church bulleting. It is printed on a laserjet printer (600 
dpi), and then copied on a copy machine. As for letters, all is right. 
But figures (photos) are this way spoiled. I guess it would help either 
to force PDF to print the figures in some very low resolution (150 dpi), 
or (probably better) to dither the figures and include them in PNG 
(instead of ordinary JPEG). Can some of you tell me how to do it? I 
tried ImageMagick's convert to dither the photos, but outcomes were 
really poor. Is there some good free software for this (in the best case 
in Linux)? Or can I do it some way in PDF?

Many thanks for any hint.

Hello Willi and others,


 Does anybody see the clue, how to tell Context to use the full marginwidth?

I strongly believe that this is a bug. left/right should change to
inner/outer on doublesided layout. But it does not (really):

\showframe
\setuppagenumbering [alternative=doublesided]
\setuplayout[backspace=1cm,leftmargin=.5cm]
\starttext
\dorecurse{4}{\input tufte \inleft{\the\hsize}\inright{\the\hsize} \page}
\showsetups
\stoptext

I have no idea what is going on.

A PostScript solution: create a dvips header file for course
rasterization:

%!
/bop-hook {53 45{dup mul exch dup mul
  add 1. exch sub}setscreen} def

These numbers (raster frequency and angle) are probably ok for
600dpi; otherwise, experiment a bit.

Call it coarse.pro and give dvips a parameter -h coarse.pro
