Oh, thanks. I found it now.
\setupscreens
  [\c!screen=0.95]
I was just too blind to find it before.

I was thinking about that as well. Having a "screen" color would be
nice for those who got used to the old name.

Mojca

In the meantime I figured it out what has happened with the "screen"
color on my display. TextMate uses Alt-Command-. for auto-completion
of "\stopwhatevercommandhasbeenstarted" in ConTeXt (an extremely
useful feature).
But Mac uses Ctrl-Alt-Command-. to increase the contrast of display.
So apparently I accidentally hit Ctrl several times without noticing
or bothering (and without knowing how to switch back), but enough to
make "95% white" disappear.

screen are gray scales, e.g. gray is defined as \definecolor[gray][s=.9]
and backgroundscreen was a mechanism to change the s value without  
defining

a new color value


I know that using it has long been deprecated, but I used it in many
older documents as it was easiest to remember without having to think
what shade of gray to use to make the highlights in document come out
nice.


in this case it would be convient to add \definecolor[screen][s=.95]
(value taken from pack-rul.mkii) to colo-rgb

[NTG-context] What color is "screen"?

[Mojca Miklavec]

Hello,

a half-philosophical question (not too relevant).

I was wondering: what color exactly is the "screen"
(\framed[background=screen]{...})? Or is it a special effect maybe?

I know that using it has long been deprecated, but I used it in many
older documents as it was easiest to remember without having to think
what shade of gray to use to make the highlights in document come out
nice.

But I just figured out that it became invisible on my screen. One can
still see it very very faintly if computer screen is under some weird
angle, but a normal glimpse shows nothing. When printed it usually
comes out with a rather high contrast. (It may be that I have just
changed screen contrast by accident.)

I was trying to find the revent line with color, but I don't find it. I noticed
grph-fig.mkii:  \c!backgroundscreen=.8,
but 0.8 is definitely higher that used in documents by default.

Thanks,
Mojca

Just a hint: the \from command of version 2009.01.18 MKIV worked very well:
- there was color

- interaction was ok
- hyphenation as with \hyphenatedurl was also ok
- possibility to add number-signs in url with "\#"


all referencing code has been rewritten so as with structure it will 
take some time for it to reach the desired state; i'm currently

[NTG-context] URLs: interaction, color/style, hyphenation (was: Re: Argument of \doswitchtotypeface has an extra })

Indeed, I suppose you mean
http://archive.contextgarden.net/message/20090504.084528.4e8ad6f9.en.html

I did not need this solution, because

1.) my little helper-macro
   \def\gotoURL{\dosingleempty\dogotoURL}
   \def\dogotoURL[#1]#2{\iffirstargument\useURL[dummyRefUseURL][#2][][#1]\else
 \useURL[dummyRefUseURL][#2]\fi\from[dummyRefUseURL]}
   worked just fine

2.) \goto{...}[url(...)] does not break URLs

But now I see, that even \from[...] does not breaks URLs neither...

It seems, the only way to get hyphenated url is without interaction.

Here a general test-file with all possibilities to print URLs, that I'm
aware of:

\setupinteraction[state=start]
\useURL[myURL][http://url.com/index.html]
\starttext
\hsize1pt
% hyphen introduced in url, no special color/style:
\from[myURL]
% same as \from, but \tt style:
\url[myURL]
% hyphenated without hyphens but no color/style/interaction:
\hyphenatedurl{http://url.com/index.html}
% interaction and color, but not hyphenated:
\goto{http://url.com/index.html}[url(http://url.com/index.html)]
\stoptext

The best would be, to have a command that:
- makes interactive links like \from[]
- uses \tt style like \url[]
- breaks URLs like \hyphenatedurl{}
- uses color like \goto{}[]

OK. The following extension would also be useful:

in mkiv syntax that is:

add a % after the } (maybe we should ignore endofline, i.e. make a mkiv 
variant and extend/maintain that)

[NTG-context] ppchtex color

[Alan BRASLAU]

No, ppchtex is not dead...

I would like to use color.

1. color= and rulecolor= does not appear to be implemented (mkiv)...
2. how can one change the color of the bonds?
3. using \color[red]{} causes the text to be offset.

"minimal" example:

\setupcolors[state=start]
\usemodule[chemic]
\starttext

\startchemical
\chemical[ONE,SB,Z0][C]
\stopchemical

\startchemical
\color[red]{\chemical[ONE,SB,Z0][C]}
\stopchemical
% text "C" is offset...

\startchemical
\chemical[ONE,SB,Z0][{\red C}]
\stopchemical
% OK, but I would like to draw the bonds as well in red.

\startchemical[color=red]
\chemical[ONE,SB,Z0][C]
\stopchemical
% "C" is red in mkii, black in mkiv

\startchemical[rulecolor=red]
\chemical[ONE,SB,Z0][C]
\stopchemical
% bonds are black, "C" is red in mkii, black in mkiv

\stoptext

Re: [NTG-context] Page background color. Does not cover the entire page.

[Curiouslearn]

Wow! Thanks for the reply. It is interesting the kind of things when using
Context or for that matter any typesetting system. I thought I chose the
letter size for my layout and I am printing it on a letter size paper. Also,
the PDF shows green everywhere. Hence, getting the color on whole page
should be easy. From your responses, it seems it is not possible because of
the way printers are designed.

-- print on larger paper and cut off the edges
-- make your layout a bit smaller and cut off the edges

only professional print will print to the edge and even then ...

(normally you will use oversized paper and bleeding)

Hi, Curiouslearn,

Generally speaking, many printers can't print a page without white
spaces about 3mm unless you have a marginless printer.

[NTG-context] ConTeXt & color=red!40!yellow

[Mojca Miklavec]

Hello,

I might be dreaming already, but on last Tuesday (I don't know which
version though) this code kept generating orange balls in ConTeXt
MKII:
\shade[ball color=red!40!yellow] (0,0) circle (.15cm);

Now I get a black one. Has anything with respect to color handling
mechanisms changed in ConTeXt MKII or TikZ recently? ConTeXt MKIV
properly generates an orange ball (usually only mkiv fails, so I'm a
bit confused now :).

I'm using ConTeXt 2009.03.30 18:28 and TikZ 2009-04-03.

Thanks,
   Mojca

Hi:

Ummm...  Same here with LuaTeX (It is ok here two or three days ago).
MKII works fine.

So I always keep a production release (ver 2005.01.31 with pdfeTeX
3.141592-1.21a-2.2) to process our journal and use the cutting edge
for fun :-)

Re: [NTG-context] Color rendering & transparency with metapost

[Renaud Aubin]

Thank Luigi for your response,  the problem is that the background color 
rendering isn't the same if you comment out or not the following line : 
draw fullcircle scaled 10cm shifted (0cm,0.25*\overlayheight) withcolor 
transparent(1,0.5,white) withpen pencircle scaled 2cm;

After some experiments, the problem is solved ( hence not understood 
???) using rgb=no in setupcolors...

It's maybe a viewer-centric problem : I use acroread 8.1.2 under linux.

[NTG-context] Color rendering & transparency with metapost

[Renaud Aubin]

Hi,

I have some trouble using a gradient background (solid) with a 
transparent element :

  \startMPinclusions
def test_shade (expr a, b) =
pickup pencircle scaled 1mm ;
color ca ; ca := \MPcolor{a} ;
color cb ; cb := \MPcolor{b} ;
color cc ; cc := \MPcolor{c} ;
sh := define_linear_shade(origin 
shifted(0cm,.5*\overlayheight),origin,ca,cb) ;
fill fullsquare xscaled \overlaywidth yscaled \overlayheight 
withshade sh;
draw origin withcolor cc;
draw origin shifted(0cm,-.25*\overlayheight) withcolor cc;
enddef ;
  \stopMPinclusions

  \setupcolors[state=start]
  \definecolor[a][r=.57254902,g=.784313725,b=.917647059]
  \definecolor[b][white]
  \definecolor[c][darkred]
  \starttext
 
  \defineoverlay[bgoverlay][\uniqueMPgraphic{bg_top_shade}]
  \setupbackgrounds[page][background=bgoverlay]
  \startuniqueMPgraphic{bg_top_shade}
test_shade(origin, origin shifted(0cm,1cm));
draw fullcircle scaled 10cm shifted (0cm,0.25*\overlayheight) 
withcolor transparent(1,0.5,white) withpen pencircle scaled 2cm;

 If you comment out the previous line the color rendering is 
definitelly different...

  \stopuniqueMPgraphic
 
  \input knuth
 
\stoptext

I have searched the ML without success, any idea ?

Regards,


Renaud

Be careful: this kills the ability of the emphasized word to be  
hyphenated!

Ok, I guess I should read what I write. What I meant was that interaction 
is added last, so everything gets overridden by interaction colors.

Hopefully, will past e the correct thing this time

\setupinteraction[state=start]

\setupfootnotes[textcolor=magenta]

\setupfootnotedefinition[before={\setupinteraction[color=blue]}]

\starttext

It gets overridden by interaction color because it is overriden by  
interaction color?

It's like a game for kids ... "who finds the 10 differences between  
Aditya's lines and Steffen's lines?"

Next try? Volunteers!

Who get's the little darkgreen footnote number paint in red ...

Because it is overridden by interaction color.

There should be a better way to do this (set interaction color and 
interaction style of each element separately), but for your case you can 
use

\setupcolors[state=start]

\starttext

\setupinteraction[state=start]

\setupfootnotes[textcolor=magenta]

\setupfootnotedefinition[before={\color[green]}]
test\footnote{test}

Ahh, now I see where my problem lays:

Despite the fact that interaction carries its own color, elements can  
be re-colored by their own color definition (see above).
Only the number of the note in front of the footnote text always gets  
overridden by interaction color!

This distinction I didn't expect.


Why should exclusively that poor little number not be allowed to have  
its own color?

\def\doemphasistypeface#1#2%
   {\doifelsevalue{\??ft\fontclass\normalizedbodyfontsize\c!em}\v!slanted
  {#1}%
  {\doifelsevalue{\??ft\fontclass\normalizedbodyfontsize\c!em}\v!italic

  {\getvalue{\??ft\normalizedbodyfontsize\c!em

however, this does not provide italic correction, so better is:

both mechanisms will be provided (maybe something emcolor later, when i

The em key is a bit extra extra special: it has to be either
'italic' or 'slanted', everything else is ignored. This is because
of the need to allow bold emphasis. (\bf\em == \bs or \bi).

I would personally be happier if it would just use whatever was
in the argument when it is *not* italic or slanted, instead of
ignoring the argument, but that's how it is.

Ah, so that is why it is lowlevel. I wonder why the following does not

\setupbodyfontenvironment [default]

Then add grouping

\define[1]\Colorit%
  {\color[magenta]{\bgroup\it #1\egroup}}

No. Instead it redefines the internals of the normal \em command.

... this looks very close to what I wrote in the same email at top:

\def\Colorit{\it\color[magenta]}

... and this had the problem of never stopping (closing) the italics  
again!


(BTW: sorry for introducing \it, I need \em of course)

This has to be used {\emphasistypeface }. If you want something that 
works as \emph{} as well as {\emph ...} and can also be passed as an 
option to all the style= keys, try

\definealternativestyle [emph] [{\it\color[magenta]}] []

You want your command to take an argument, so you have to mention that  
argument in the definition (untested):

\define[1]\Colorit%
   {\color[magenta]{\it #1}}

It should be something like \Colorit{this} example:

But this above never closes the italics, while ...

... gives an error.

[NTG-context] how to color italics?

Hi,

for making editing easier I'd like my italics (\em) to be in PDF   
typeset colored.

Something like \setupem[color=blue]


How can this be done?

[NTG-context] Verbatim with color background

[B. Tommy Jensen]

Hi,
I have a short question about verbatim areas (\starttyping):

I have been trying to define a background color to verbatim
areas in a document. My method so far is to define a
textbackground named "verbatim" and refer to this in the
setuptyping method:

\setuptyping[typing][margin=0.5cm,bodyfont=8.0pt,
before={\starttextbackground[verbatim]},
after={\stoptextbackground}]

This works only partly. For example, when using long
verbatim texts that spans over more than one page,
the background color disappears on the last page.

Is there any other easy way of controlling the background
color on verbatim areas?

Best regards,
Tommy Jensen

So perhaps as expected it turns out that the limitation was only in my

[NTG-context] Color in math in MkIV

[Aditya Mahajan]

Hi,

The color commands do not work inside math mode in MKIV. For example

$f(\color[blue]{A}) = b$

$f({\blue A}) = b$

come out black and

$f(\blue{A}) = b$

colors everything blue. I have an easy work around for the moment:

\unprotected\def\mathcolor[#1]#2%
   {\preparebinrel{#2}
[EMAIL PROTECTED] #2$}}}


and then use \mathcolor.

Aditya

Thanks - this also now works! The "context" utility built the format
automatically while I had to run the command manually with "texexec"
(So "context" seems to be smarter than "texexec").

My installation is the "complete windows environment" of context. I ran
the "fist_setup.bat" batch file after installation; this built many  
formats.
I don't know why the metafun format wasn't built - perhaps something
is missing from the setup file?

In any case - thanks a lot for the good advice.

Best regards,
Tommy Jensen

Thanks a lot for pointing me in the right direction!

I was using the "texexec" utility. When I tried the same with the "context"
version, it rebuilt some formats and it now works exactly as expected.

Sorry for being a novice here; is it so that the "texexec" utility should
be consiered as obsolete?

Thanks for the prompt reply!

I have tried to add background=color as an option, but the result is  
exactly the same;
only the text gets colored; no frame and no background color appear.

Do you have other ideas?

But MkII should work too. Try "texexec --make metafun --alone" and now
"texexec myfile".

[NTG-context] Missing background color with \definetextbackground

[B. Tommy Jensen]

Hi,
I am strugglig to get the background color visible with the following code:

%
\setupcolors[state=start]
\definetextbackground[highlight][backgroundcolor=yellow,
 frame=on,
 location=text,
 color=blue]
\starttext
\starttextbackground[highlight]
This text should have yellow background but it is white.
The text is however blue.
\stoptextbackground
\stoptext
%-

The background of the rendered text is always white, independent of the
backgroundcolor parameter. The font color is however OK (blue).
All other samples I have tried from "details.pdf"
behaves similarly - no background color and no frame/frame color.

I am using the latest complete standalone Windows version of Context.

Has anybody encountered a similar behaviour?

Tommy Jensen

well, white is not the best test example

\unprotected\definetextext[parbox]
{\framed
  [ width=2cm,
   height=.85cm,
    autowidth=no,
align={middle,middle},
  background=color,
  backgroundcolor=white]}

\startMPpage[background=color,backgroundcolor=red]
draw (0,0) -- (3cm,3cm) ;
label(\sometxt[parbox]{ABC}, (1.5cm,1.5cm)) ;
\stopMPpage

works ok here

after this fix you need to do

ctxtools --touch
context --make

otherwise the mplib format will not be regenerated; normally this
happens automatically when a new version is installed

Re: [NTG-context] Background color spaning columns.

Thanks for the insight.  I'll give it a try with columnsets.

I have encountered this problem in the past. This is a limitations of the 
simple column mechanism.

Use columnsets. They are not as easy and simple as columns, but they 
provide a lot more features. See the columnset manual for details about 
using them.

[NTG-context] Background color spaning columns.

[Bart Wise]

I am trying change the background color of some text.  It works fine if I am 
using one column.  It also works fine if I am using multiple columns, but 
restricting my background color changes to only a single line of text in a 
column.  

However, if I have a section that I want to I change, and that section spans 
more than one line in a given column it does not work.  What happens is that 
the background starts to change where you have indicated; however, instead of 
stopping at the end of the column, the background color changes for the 
entire text.  See the subject entitled "Problem 1" below for an example.  Is 
there a fix for this (and no, using a single column is not a solution.)

Problem #2 is the same thing only the background change starts in the first 
column and extends to the second.  In this case the output is even worse.  
It's difficult to describe, so run the code.

Solutions?

Thanks,
Bart

The problem is that it defines things, and you can't do that inside
an argument. Solution: rewrite the macro to define a new macro
(like \def\currentStateDependentColor{green}) instead of expanding
on the fly. Then you have to do something like this:

   \StateDependentColor[stateA=green,stateC=blue,whatever=yellow,...]
   \ color[\currentStateDependentColor]

And that should work.

Best wishes,
Taco

this is what color palets are for .. grep a bit on the base path; it's 
even in some manuals

if you use colorpalets, then you can change the state of many colors at 
once with one command

It is hard to give a better solution because I don't what do you want to achive
and how your interface should look to change the states and colors ...
