TikZ bug in ConTeXt

Hi,

Anyone could help me with this bug: http://www.ntg.nl/pipermail/ntg-context/2014/077374.html
It seems that ConTeXt does not change the TikZ color. I don't know it it's context or tikz bug.

Can anyone test it?
I use context minimals.

Thanks in advance,
Xavier

pgf 3.0 manual nonlineartransformations example

Dear all,

today I installed MacTeX2014 on my computer, mainly because of pgf 3.0.
I want to explore this cool new nonlineartransformation feature and
started by testing the examples from the manual (starting p. 1057).
By surrounding the \def\polartransformation with a pair of \makeatletter
\makeatother I was able to get the polar transformation working.

Now I am stuck with the examples regarding the curvilinear library...
I am getting an error
"! Undefined control sequence.
<argument> \pgf
l.14	\draw (0,-30pt) grid [step=10pt] (80pt,30pt);
?"
with the following code:

\documentclass[tikz]{standalone}
\usepgfmodule{nonlineartransformations}
\usetikzlibrary{curvilinear}
\begin{document}
\begin{tikzpicture}
\draw [help lines] (0,0) grid (3,2);
{
\pgfsetcurvilinearbeziercurve
{\pgfpoint{0mm}{20mm}}
{\pgfpoint{11mm}{20mm}}
{\pgfpoint{20mm}{11mm}}
{\pgfpoint{20mm}{0mm}}
\pgftransformnonlinear{\pgfpointcurvilinearbezierpolar\pgf <at> x\pgf <at> y}%
\draw (0,-30pt) grid [step=10pt] (80pt,30pt);
% Add a "barb":
\draw [blue, very thick] (20pt,10pt) -- (0,0) -- (20pt,-10pt);
}
\draw[red, very thick]
(0mm,20mm) .. controls (11mm,20mm) and (20mm,11mm) .. (20mm,0mm);
\end{tikzpicture}
\end{document}

This is working, however, with the \polartransformation in effect (and
eliminated \pgfsetcurvilinearbeziercurve{}{}{}{} and curvilinear library).

Reading the manual, I would expect the \pgfpointcurvilinearbezierpolar
to have two arguments {}{}, missing in the code. But just putting \pgf <at> x
and \pgf <at> y there doesn't do the trick. (Don't laugh at me, I don't know
anything about this low level commands and was just trying...)

Do you have any suggestions?

Thanks and all the best,
Anuschka

document class change causes tikz errors

I have a flowchart that works in the article document class, but when I
change document class to mnthesis, it does not recognize tikZ.  Any ideas? 
Does the document class file (mnthesis.cls) have to inside the Latex program
file to be activated, or does it just need to be in the same folder as the
test1.tex file?  Here is a file of my flow chart (test1.tex).  Next is a
file of the 'mnthesis.cls' file.  Any help is appreciated.

pgfpages: reordering of pages

Hi folks,

I use pgfpages a lot, but there's one feature I would like to use which I don't 
know how to access (or whether it's possible at all): Is there a way to place a 
shipout command between the created logical pages? I would like to use this for 
example for the creation of booklets.

Here's a short non-working example. It creates two logical pages (A4), which I 
would like pgfpages to output unchanged, but with their order reversed:

\documentclass[a4paper]{scrartcl}
\usepackage[a4paper,margin=5mm]{geometry}
\usepackage{pgfpages}
\pgfpagesdeclarelayout{switch 2}
{
     \edef\pgfpageoptionheight{\the\paperwidth}
     \edef\pgfpageoptionwidth{\the\paperheight}
     \def\pgfpageoptionborder{0pt}
}
{
     \pgfpagesphysicalpageoptions
     {%
         logical pages=2,%
         physical height=\pgfpageoptionheight,%
         physical width=\pgfpageoptionwidth,%
     }
     \pgfpageslogicalpageoptions{2}
     {%
         resized width=\pgfpageoptionwidth,%
         resized height=\pgfpageoptionheight,%
         center=\pgfpoint{.5\pgfphysicalwidth}{.5\pgfphysicalheight},%
         %%% execute shipout after placing this page! %%%
     }%
     \pgfpageslogicalpageoptions{1}
     {%
         resized width=\pgfpageoptionwidth,%
         resized height=\pgfpageoptionheight,%
         center=\pgfpoint{.5\pgfphysicalwidth}{.5\pgfphysicalheight},%
     }%
}
\pgfpagesuselayout{switch 2}[a4paper]
\begin{document}
page one
\newpage
page two
\end{document}

Thanks for any help,

	Susan

PS: I know that pdfpages could be an alternative, but for several reasons I 
would love to stick to pgfpages for this project.

TikZ 3.0 & preview

Hello,

I have a problem with the new TikZ 3.0, it produces the same "error" by
using MikTeX or an updated TeXLive.

The following document:

\documentclass{article}

\usepackage{tikz}
\usepackage[delayed,tightpage]{preview}

\listfiles
\begin{document}
\begin{preview}
XXX
\end{preview}
\end{document}

Produces the following error:
! Undefined control sequence.
\ <at> EveryShipout <at> Output ...EveryShipout <at> Org <at> Shipout
                                                  \box \ <at> cclv
l.11 \end{document}

If the preview package is active, then there will be no error.

There is a hack of handling the preview package in the file
pgfutil-latex.def (in line 136):
\AtBeginDocument{
  \ <at> ifpackageloaded{preview}{%
    \let\pgf <at> temp\pr <at> shipout%
    \let\pr <at> shipout\ <at> EveryShipout <at> Shipout%
    \let\ <at> EveryShipout <at> Org <at> Shipout\pgf <at> temp%
  }{}%
}

if I change this into:
\AtBeginDocument{
  \ <at> ifpackageloaded{preview}{%
    \let\pgf <at> temp\pr <at> shipout%
    \let\pr <at> shipout\ <at> EveryShipout <at> Shipout%
    \ifPreview%
      \let\ <at> EveryShipout <at> Org <at> Shipout\pgf <at> temp%
    \fi%
  }{}%
}

everything works like expected. But I'm unsure if than something else is
broken, since I'm really unsure if this is really a solution for the
problem above.

Best regards
Christoph

Incompatible library "graphs" and "shapes"? -> Compilation error.

Hello,

I need to use the TikZ libraries "graphs" and "shapes" in the same document. But they seem to be incompatible. Here is a minimal example that makes active use of the "graphs" library, but does not need the "shapes" library. Anyway, the compilation fails as soon as the "shapes" library is loaded.

This is the minimal example:

\documentclass{minimal}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\usepackage{tikz}

% If the TikZ library 'shapes' is loaded, compilation fails
\usetikzlibrary{shapes,matrix,graphs}
%\usetikzlibrary{matrix,graphs}

\begin{document}
\begin{tikzpicture}
\matrix { \node(foo) {foo}; \\ \node(bar) {bar}; \\ };
\graph[use existing nodes] { foo -> bar; };
\end{tikzpicture}
\end{document}

The error message is

! Missing \endcsname inserted
<to be read again>
\tikz <at> lg1
l.17 \graph[use existing nodes] { foo -> bar; };

I use the package versions that are bundled with my LaTeX distribution. This is to say:

- MikTex 2.9
- pgf 2008/01/15 v2.10 (rcs-revision 1.12)
- tikzlibraryshapes.code.tex 2008/01/09 v2.10 (rcs-revision 1.1)
- tikzlibrarymatrix.code.tex 2008/06/18 v2.10 (rcs-revision 1.2)
- tikzlibrarygraphs.code.tex 2010/10/23 v2.10 (rcs-revision 1.1)

Any ideas?

Best regards, Matthias Nagel

\pgfmath<operation> works -- but \tikzmath does not


%% Plain TeX file
\input tikz.tex
\usetikzlibrary{mindmap,intersections,arrows,angles}
\usetikzlibrary{quotes,calc,decorations.pathmorphing}
\usetikzlibrary{backgrounds,positioning,fit,petri}
\usetikzlibrary{math}

The following calculates the angle PFQ.  Use of pgfmath<operation> 
results in the expected answer of 60 degrees.  However, use of 
tikzmath{} results in error message: Runaway argument?  ! Paragraph

Circular arcs defined by an 'X' -- plain TeX (and TikZ)


%% Plain TeX file
\input tikz.tex
\usetikzlibrary{mindmap,intersections,arrows,angles}
\usetikzlibrary{quotes,calc,decorations.pathmorphing}
\usetikzlibrary{backgrounds,positioning,fit,petri}
\baselineskip=12pt
\hsize=6.5truein
\vsize=9.0truein
\parskip 6pt

% Here's the question on
% "Circular arcs defined by an 'X' -- plain TeX (and TikZ)":

Consider three points P, Q, and F, with F being below the line
joining P and Q.  So the two lines PF and QF would form a distorted
`V', and extending these two lines would result in a distorted `X'.
Introduce 5 points into the shorter of the two segments PF and QF,
so that this shorter segment is divided into six equal sub-segments.

Need to use these 5 points to draw circular arcs in {\bf TikZ} and
{\bf plain \TeX} ({\bf not} latex).

I can illustrate what needs to be done for the special case of P, Q
and F being (-3,  0), (3,  0), and (0, -3*sqrt(3)).

Would like pointers to extending this to the general case.

Problem with a path between pgf 2.1 and pgf 3.0

Hello

I asked this question on the site tex.stackexchange :
With the next code and pgf 2.1 I get identical pictures but
with pgf 3.0 the pictures are different. It seems it is a bug
with external gnuplot function plot but I would like to find some explanations

\documentclass{standalone}
\usepackage{tikz}
\begin{document}

  \begin{tikzpicture}[domain=0:2]
    \path[fill=blue]  (0,0) -- plot function{x+1} -- (2,0);   
 \end{tikzpicture}

\begin{tikzpicture}[domain=0:2] 
\path[fill=blue]  plot function{x+1} -- (2,0) -- (0,0);    
\end{tikzpicture}

\end{document}

Best regards

How to rebuild the manual pgfmanual.pdf?


Hello,

On Windows 7, 64 bit with MikTeX, the installed pgfmanual.pdf  (Manual 
for version 3.0.0 dated December 20, 2013) has a page size of 8.27 x 
11.69 and 1165 pages.

I tried to build the manual from sources as follows:

      cp -iar /c/opt/miktex_2.9/doc/generic/pgf  .
      cd  pgf/version-for-pdftex/en/
      make

The preceding command compiled the sources twice and ended with success. 
  However, the resulting pgfmanual.pdf has less than 1000 pages and is 
still of size 8.27 x 11.69.

How do I get all the content of the deployed manual but with page size 
of 8.5 x 11?

Thanks,

--Suresh
