Re: [NTG-context] colors in pgf within context
Hi Aditya,
Thanks for the help -- I think I now see why there is such trouble with
colors in pgf and context. It looks like one can systematically
transform LaTeX-like PGF examples of \color into ConTeXt examples.
The reason why this came up is that I'm trying to go through Till
Tantau's "Example for Karl's Students" tutorial in the PGF/TikZ manual.
Has anyone managed to ConTeXt-ify that example? The closest that I've come is
\usemodule[tikz]
\setupcolors[state=start]
\starttext
\starttikzpicture
[scale=3,
line cap=thin,
%Styles
axes/.style=,
important line/.style={very thick},
information text/.style={rounded corners,fill=red!10,inner sep=1ex}]
% Local definitions
\def\costhirty{0.8660256}
% The graphic
\draw[help lines,step=0.5cm] (-1.4,-1.4) grid (1.4,1.4);
\draw (0,0) circle (1cm);
\startscope[axes]
\draw[->] (-1.5,0) -- (1.5,0) node[right] {$x$} coordinate(x axis);
\draw[->] (0,-1.5) -- (0,1.5) node[above] {$y$} coordinate(y axis);
\foreach \x/\xtext in {-1, -.5/-\frac{1}{2}, 1}
\draw[xshift=\x cm] (0pt,1pt) -- (0pt,-1pt) node[below,fill=white]
{$\xtext$};
\foreach \y/\ytext in {-1, -.5/-\frac{1}{2}, .5/\frac{1}{2}, 1}
\draw[yshift=\y cm] (1pt,0pt) -- (-1pt,0pt) node[left,fill=white] {$\ytext$};
\stopscope
\filldraw[fill=green!20,draw=green!50!black] (0,0) -- (3mm,0pt)
arc(0:30:3mm);
\draw (15:2mm) node[green!50!black] {$\alpha$};
\draw[important line,red]
(30:1cm) -- node[left=1pt,fill=white] {$\sin \alpha$} (30:1cm |- x axis);
\draw[important line,orange!80!black] (1,0) -- node[right=1pt,fill=white] {
$\displaystyle \tan \alpha \color[black]{=}
\frac{\color[red]{\sin \alpha}}{\color[blue]{\cos \alpha}}$}
(intersection of 0,0--30:1cm and 1,0--1,1) coordinate (t);
\draw (0,0) -- (t);
\draw[xshift=1.85cm]
node[right,text width=6cm,information text]
{
The \color[green!50!black]{angle $\alpha$} is $30^\circ$ in the
example ($\pi/6$ in radians). The \color[red]{sine of
$\alpha$}, which is the height of the red line, is
\startformula
\color[red]{\sin \alpha} = 1/2.
\stopformula
By the Theorem of Pythagoras ...
};
\stoptikzpicture
\stoptext
The example features some \definecolor's which I just did away with
(sadly) by simply substituting their defining values for their
occurences. (This is unfortunate, but perhaps necessary until some
other mechanism is produced.) The problem is that the text box to the
right of the picture is supposed to be colored, and with rounded
corners. But the box is missing. Look at p. 20 of
http://altermundus.com/downloads/pgfmanual_cvs.pdf
to see what I mean. Also, the phrase "angle $\alpha$" is supposed to be
in a kind of green, but that's not working either. What might be
happening?
Thanks,
Jesse

I did that some time back while testing tikz. I will send that file as a
reply to this email, since I am not sure if it will go through the mailing
list because of its size.

The TikZ manual make a lot of uses of the xcolor syntax (e.g.
\color{red!20}). There is no equivalent ConTeXt syntax. You need to define
a color, say lightred, as follows
\definecolor[lightred][r=0.2]
For tikz key-value options, pgf works behind the scene to define
appropriate colors, so xcolor syntax works for them. So
\fill[fillcolor=red!20] will work as expected. However, when using \color
inside any box, you need to follow ConTeXt syntax. So \color[red!20] will
not work, you need to define a context color and then use that.
Hope that this clarifies some things.
Aditya

No, the reason for the error is more subtle. PGF does try its best to work
with ConTeXt colors. However, there is a difference between latex and
context color usage, that gives rise to the error. The culprit in this
case is:
{$\displaystyle \tan \alpha \color{black}=
\frac{{\color[red]\sin \alpha}}{{\color[blue]\cos \alpha}}$}
Try this in a standalong context file (no pgf) and you will get an error.
First you need to change \color{black} to \color[black]. Even then you
will get an error. You need to use
{$\displaystyle \tan \alpha {\color[black]=
\frac{{\color[red]\sin \alpha}}{{\color[blue]\cos \alpha}}}$}
(Notice the {...} around \color[black]). Then everything works fine. Here
is a working example (latest pgf from cvs, but should also work with
1.18).

\setupcolors[state=start]

\clip (-2,-0.2) rectangle (2,0.8);

\draw[very thick,red]
(30:1cm) -- node[left=1pt,fill=white] {$\sin \alpha$} (30:1cm |- x
axis);
\draw[very thick,blue]
(30:1cm |- x axis) -- node[below=2pt,fill=white] {$\cos \alpha$}

\draw[very thick,orange] (1,0) -- node [right=1pt,fill=white]

no, just a side effect ... if you reshuffle the pages, you will get
different flushing of multipass data
(so, in fact you need to do normal runs, and then a final arrange run
with --once)
normally, you'll do:
texexec yourdoc --arrange
which will do normal runs followed by an extra run that arranges

[NTG-context] Bug? Cross referencing and \setuparranging
Hi,
There seems to be a bug with the current ConTeXt (2008.01.28).
When using \setuparranging (I've tried more than one setup),
cross-referencing doesn't work. You get ?? instead of whatever number
you should get. It happens to me with this simple dummy document:
\setuppapersize[A5][A3]
\setuparranging[2UP,doublesided]
\starttext
\chapter[chap1]{Chapter One}
\dorecurse{4}{\input knuth \par}
\chapter[chap2]{Chapter Two}
\dorecurse{4}{\input knuth \par}
\chapter[chap3]{Chapter Three}
In chapter \in[chap1] of this document, there was something to read.
\stoptext
If you comment out the \setuparranging command, the \in command will
work. If you don't, the log shows the following:
chapter : 3 Chapter Three
references : unknown reference [][chap1]
This looks like a bug?
