	*===========================================*
		The Tkzinc widget version 3.6
	*===========================================*


WHAT IS THIS?

  Tkzinc is a canvas like widget extension to Tcl/Tk. It adds
support for ATC displays, provides structured assembly of
items, transformations, clipping, and openGL based rendering
features such as gradients and alpha blending.

  It is currently available on Unices (tested on Linux),
Windows and Mac OSX (with X11 and fink).


WHERE DOES IT COME FROM?

  The newest version is found at: https://bitbucket.org/plecoanet/tkzinc
  It should be at least available in source form in a file
  named Tkzinc<version>.tgz.
  Distribution specific packages may also be available for
  Debian/Mandrake/Red Hat distributions, most likely for stable
  versions.

  For Tcl/Tk users, Tkzinc is also available as a multi-plateforme
  (linux/windows) starkit on https://bitbucket.org/plecoanet/tkzinc
  For Perl/Tk users, Tkzinc is available on the CPAN, see for example
  on http://search.cpan.org/search?query=TkZinc&mode=all

  As a convenience the documentation (pdf+html) is made available
  on the web site as a separate package.


BUILDING AND INSTALLATION FOR TCL/TK


0. You need a working Tcl/Tk distribution (version >= 8.4). You can either grab
   it using your regular package manager, or build it and install it from scratch.

   On a Linux system, you need tcl tcl-dev tk tk-dev packages.

   On MacOSX you need:
	- fink with tcltk and tcltk-dev package (http://fink.sf.net)
	- tcl/tk sources, though you are _not_ required to compile and install them.
	tcl/tk sources are needed  because some required files are missing in the packages (tclInt.h and tkInt.h,
	if you know how to get those files with fink, submit a suggestion to the maintainers).
	I couldn't install them using fink, d/l them instead:
		http://prdownloads.sourceforge.net/fink/direct_download/source
	- X11 et X11 sdk from Apple (http://www.apple.com/macosx/x11/)

   From sources or on Windows, get, build and _install_ the Tcl/Tk distribution.
   On Windows there is currently an incompatibility when using a Tkzinc compiled under mingw32 with
   a core Tcl/Tk compiled with visual C++. You need to grab a Tcl/Tk
   compiled with the same environment as Tkzinc.


1. Unpack the distribution

   On Unix/Linux/MacOSX:

	tar zxf Tkzinc<version>.tgz

   On Windows:

	Use WinZip or something similar to unpack

   This creates a directory Tkzinc<version> with all the
   needed files. This directory should be in the same
   directory as the Tcl/Tk sources.


2. Configure

   On Unix/Linux:

	cd Tkzinc<version>
	./configure  <option>*

   This will configure the package for your platform. It
   will install it in /usr/local. If you want it elsewhere
   you can use the --prefix and --exec-prefix options of
   configure to assign another location.

   On MacOSX:

   say we have unpacked tlc/tk sources in $HOME/src. The configure
   line is as follows: 
             env "CPPFLAGS=-I/sw/include -I$HOME/src/tcl8.4.1/generic -I$HOME/src/tk8.4.1/generic" ./configure --with-tcl=/sw/lib --with-tk=/sw/lib --enable-gl

   On Windows:

   Tkzinc has been built using the msys/mingw32 environment.
   It is known to work with Tcl/Tk 8.4.2 compiled using the
   same environment. CAUTION: It doesn't work with Tcl/Tk 8.4.1
   using mingw32.
   The steps for building under mingw32 are the same as on Unices.
   Currently there is no support for building with visual C++.

   On all platforms:

   It is possible to customize Tkzinc through configure options:

	--enable-gl=[yes|no|damage]
	--disable-gl

	This is turned off by default. Building with --enable-gl
	is the recommanded way for openGL support.

	--enable-om=[yes|no]
	--disable-om

	This is turned on by default. It controls the inclusion of
	code for avoid overlap between track labels in radar images.

	--enable-shape=[yes|no]
	--disable-shape

	This is turned on by default except on Windows where support
	code is not currently available (it may become available).
	It allows for non rectangular Tkzinc windows optionally including 
	the top level window.

   And the Tcl standards:

	--enable-threads=[yes|no]
	--disable-threads

	Compile a thread aware/thread safe version (not tested in multi
	threaded environment). Needed if Tcl/Tk has been compiled with
	the same configure option.

	--enable-symbols=[yes|no|mem|all]
	--disable-symbols

	Turn on debugging symbols. If the form --enable-symbols=mem is 
	used, turn on memory debugging as well.


3. Make and Install

   For use with Tcl on Unix/Linux and Windows using mingw32:

	make
	make install-tcl

   It is recommended to do a make distclean before actual building if you
   have done a previous build.

   The warnings while compiling libtess are harmless (or so I believe ;-).
   libtess is a tesselation library extracted from GLU/Mesa. I trust it as
   robust unless proven wrong. I do not want to modify the code just to
   shut up some warnings.


   For use with Tcl on Windows using Visual C++:

	nmake /F win/makefile.vc

   There is no install target. You are left with the dlls and the start of
   pkgIndex.tcl (it lacks the entries for the Tcl modules in library).
   It is needed to compile with Visual C++ if Tkzinc is to be used with a
   Tcl/Tk compiled with Visual C++.

   P.S: If a pkgIndex.tcl for Tkzinc exists in the autoload path before
   installing, it will interfere with the generation of the new pkgIndex.tcl.
   It should be removed or renamed. echo 'puts $auto_path' | tclsh will
   tell the current load path.
   
   WATCH OUT! On Linux it is quite frequent to have both Mesa and proprietary
              openGL libraries installed. This may lead to big problems at
	      runtime if the linker picks the wrong library. It is often the
	      case between the static (libGL.a) Mesa library and the dynamic
	      (libGL.so) NVidia library. It is very important to assert that
	      the link is done with the library matching the openGL driver
	      loaded in the X server.

4. Run the demos

   In the Tkzinc<version> directory run:

	wish8.4 demos/zinc-widget

   Under windows do:

	wish84 demos/zinc-widget

   It should start a Tk like 'widget' demo showing Tkzinc
   features. You can also run the demo with: demos/zinc-widget
   if you have in the PATH a wish that is greater or equal to
   8.4.2.


BUILDING AND INSTALLATION FOR PERL/TK

TkZinc for Perl/Tk is available for Linux, Windows (Perl/Tk 804)
and MacOSX. Also remember that the easiest way could be to use
the CPAN. However new releases are usually first available on
https://bitbucket.org/plecoanet/tkzinc


0. You need a working Perl (>= 5.6) and Perl/Tk distribution (800 or 804). You can either grab
   it using your regular package manager, or build it and install it from scratch. To build it
   from scratch you need:

   On a Linux system, you need perl, perl-tk and perl-tk-devel packages 

   On MacOSX you need:
      - fink with tk-pm package and its dependencies (http://fink.sf.net)
        tk-pm is available in unstable. You can add this binary unstable tree to you /sw/etc/apt/sources.list:
        deb http://fink.opendarwin.org/bbraun 10.3/unstable main crypto
        deb http://fink.opendarwin.org/bbraun 10.3/stable main crypto
     - X11 et X11 sdk from Apple (http://www.apple.com/macosx/x11/)

   On WinXP you need:
      - perl and perl-tk 804, 
      - Visual C++ or the Free Visual C++ Command Line Tools

1. Unpack the distribution

        tar zxf Tkzinc<version>.tgz
        cd Tkzinc<version>/Perl
        ./export2cpan
        cd ../export2cpan/tk-zinc<version>

2. Make and install

    This done is the usual way

        perl Makefile.PL
        make
        make test

        # to run the demo without/before installing:
        perl -Mblib demos/zinc-demos

        make install

   WATCH OUT! On Linux it is quite frequent to have both Mesa and proprietary
              openGL libraries installed. This may lead to big problems at
	      runtime if the linker picks the wrong library. It is often the
	      case between the static (libGL.a) Mesa library and the dynamic
	      (libGL.so) NVidia library. It is very important to assert that
	      the link is done with the library matching the openGL driver
	      loaded in the X server.

3. Run the demo

    You can choose in the 35 available demos with the
    following perl script:

        zinc-demos


MAKE AND READ THE DOCUMENTATION


   It is available in pdf and html forms.
   To make the pdf doc you need pdflatex installed. Then do:

	cd Tkzinc<version>
        ./configure
	make pdf

   This should create a refman.pdf in the doc directory.

	cd Tkzinc<version>
        ./configure
	make html

   This should create the html documentation in the doc directory
   with all the html pages and images. The entry point is index.html.
   You need tex4ht for doing this. It may be packaged separately from
   tetex on Linux, it is so on Debian distributions.
