Colors in DVI output

Colors in DVI output

[Giuseppe Bilotta]

Hello,

I'm using ConTeXt on a MiKTeX distribution, and I seem not to be able to
activate the colors in DVI output. I have \setupcolors[state=start], and I
get them in PDF mode. Also, colors are there after a dvips, in the ps file.
How do I tell ConTeXt to use an alternative (non-ps) color specials
impementation? (possibly one understood by MiKTeX)

I suppose that you want to use a dvi viewer? Which one? Since there is no
standard on this, you need to load the appropriate special driver
[\setupout] but maybe there is no context special driver yet for your
viewer. No big deal, but i must know the specific specials then. Some
specials, like color, can be run in parallel without problems.

Since I use MiKTeX, my dvi viewer is YaP. It accepts various color special
formats ---for sure (I used it in latex), it accepts the one issued by the
dvipdfm option in the color package (the format is something like: "color
push <values>" and "color pop"

I need the more stupid ones, since I push and pop myself (more robust). Is
there some documentation for yap specials?

I don't think there are ypa specials: it uses already-defined specials
(those used by dvipdfm for sure, and some others too).

In my ConTeXt-produced dvi the color specials are ps specials. I think yap
simply ignores those. maybe not prefixing those specials with "ps" would
help ...

You may then try: 

\setupoutput[dvipdfm]

since there is a driver for dvipdfm (although minimally tested).

 This doesn't work for YaP but \setupoutput[dvipsone] does.

I'll leave the gurus to work out the post-mortem... :-)

\setupoutput[dviwindo] did the trick.

Experimenting with the various outputs to find one compatible with YaP, I
found that dvipdfm makes the "color specials" disappear (a raw search for
"color" in the dvi file only gets the words of text containing the root
"color", and no specials). Is this correct?

dvi is a binary opcode language so you will only see the text that goes
into the special [there are 4 kind of special opcodes] so 'color' in this
case. 

You can take a look at spec-yy and spec-win to see what codes are output.
Actually, we need a spec-yap.tex file.

I knew that. But all the color specials have "color" in their text, don't
they? (Ok, maybe dvipdfm color specials don't).

I can ask Christian Schenk [isn't he the MiKTeX maintainer?] for a list of
specials recognized by yap.
