[Plplot-general] tcl and [incr tcl]

[Cavendish M. <cm...@mo...>]

I'm a little confused about tcl and [incr tcl] dependencies for
plplot.  Plplot doesn't want to compile with tcl 8.0, but the latest
version of [incr tcl] I have found seems to require tcl 8.0.x.  Am I
missing something somewhere?

[Plplot-general] plplot-5.0.1 has been released.

[Alan W. I. <ir...@be...>]

Get this new stable version as a tarball file release at
http://sourceforge.net/projects/plplot.  It was created from the current
CVS head which has benefited quite a lot from steady bug fixing over the
last few months.  Version 5.0.1 supersedes all previous versions.
(Please note that for stability you should use the tarball release and
not the CVS HEAD.  We ordinarily make no guarantees about the stability of
the HEAD since we want to be free to try things on the HEAD which might
break plplot from time to time.)

Note we also have some innovation in the new release as well as bug fixing.

(1) The documentation building process has been changed completely over to
DocBook 4.1 XML.  To see the nice html, postscript, pdf, dvi, info, and man
results of this effort, please look at
http://www.plplot.org/resources/docbook-manual/

(2) The content of the documentation source has been greatly improved from
previous versions.  However, more work is always needed on documentation
content, and if you have an interest in helping out with this aspect of
plplot, please contact yours truly (Alan W. Irwin).

(3) The header file style has been changed to be similar to that of X.  That
is every header file reference in source should have the prefix plplot, e.g.,

#include "plplot/plConfig.h"

This gives much less potential for nameclashes, if the headers are stored in,
e.g., /usr/include/plplot.  It also means that the -I parameter stays the
same as it was before on the compile line.

(4) The library names have been changed so they are in a more consistent style
now that gives more protection against nameclashes.  All library tags 
(suffixes to the core name of libplplot, libplmatrix, etc.) are
now gone except for d for double precision and nothing for single precision
or the libplmatrix library (which is always single precision even if
you have configured double precision).  To indicate what the library names
that were used to build plrender, execute the installed
$prefix/bin/plplot_linkage.  On my current system this emits the following
line:
-L/usr/local/plplot/lib -lplplotd -lplmatrix -litk3.1 -ltk8.2 -litcl3.1
-ltcl8.2 -L/usr/X11R6/lib -lX11 -lvga -ldl -lm -lg2c -Wl,-rpath
-Wl,/usr/local/plplot/lib

Your system (if it isn't Debian potato) will have a different link line
emitted by $prefix/bin/plplot_linkage.  That is the one to use!

(5) Python now works! (at least in widgetless mode).  Configure python (which
happens by default), and try out the new widgetless examples, xw??.py.
You will like them!  These examples all require double precision.  Eventually,
we plan to add Tk widget capabilities to these examples.  Any help
would be appreciated.

(6) Fortran now works with double precision and Linux!  (It always worked
well with single precision before, but it is nice to have this generality.)

Tests:

Release version 5.0.1 has been extensively tested on Debian potato with double
precision configured. The cdemos, cxxdemos (c++), fdemos (fortran),
tcldemos, tkdemos, and the new standalone xw??.py python demos all now work
well on potato. Similar tests show good results on RedHat 6.2 except for
Tcl/Tk whose 8.0 version on RH 6.2 is too old for us to support. We have not
yet upgraded our test box to RedHat 7.0, and until we do, we would
appreciate any RedHat 7.0 reports our users could give us. We have also been
able to configure, build, and install the software on a solaris system, but
so far only minimalist testing has been done on that system.  

Putting on my yplot (http://sourceforge.net/projects/yplot) hat momentarily,
I have recently rebuilt yplot, the convenient yorick front end to plplot.
The new yplot version (to be released soon) is based on plplot-5.0.1
libraries, and I have just confirmed it gives excellent results for a wide
variety of 36 different scientific plots from my present research.

Please send bug reports, comments, and questions to this list, and
have fun (and profit) with the new 5.0.1 release of plplot!

[Plplot-general] 3 important changes in the cvs HEAD version of PLplot

[Alan W. I. <ir...@be...>]

In the last couple of weeks I have completed 3 important changes to plplot
that will affect all users using the current cvs HEAD.

(1) Because of name clash concerns the header naming style has now been
changed to the same style used by X.  The installed headers now are in
their own subdirectory called plplot:

irwin@starling> ls -l /usr/local/plplot/include/plplot
total 184
-rw-rw-r--    1 software software    10372 Dec 27 17:39 drivers.h
-rw-rw-r--    1 software software     4132 Dec 27 17:39 pdf.h
-rw-rw-r--    1 software software     3157 Dec 27 17:39 plConfig.h
-rw-rw-r--    1 software software     1771 Dec 27 17:39 plDevs.h
-rw-rw-r--    1 software software     1382 Dec 27 17:39 plcdemos.h
-rw-rw-r--    1 software software     2567 Dec 27 17:39 pldebug.h
-rw-rw-r--    1 software software     7321 Dec 27 17:39 plevent.h
-rw-rw-r--    1 software software    46264 Dec 27 17:39 plplot.h
-rw-rw-r--    1 software software    17170 Dec 27 17:39 plplotP.h
-rw-rw-r--    1 software software    22275 Dec 27 17:39 plstream.h
-rw-rw-r--    1 software software    20290 Dec 27 17:39 plstrm.h
-rw-rw-r--    1 software software     2052 Dec 27 17:39 pltcl.h
-rw-rw-r--    1 software software      979 Dec 27 17:39 pltk.h
-rw-rw-r--    1 software software     5115 Dec 27 17:39 plxwd.h
-rw-rw-r--    1 software software    11945 Dec 27 17:39 tclMatrix.h

When compiling, the -I directory should remain the same (pointing to
$prefix/include), but your source code should change all occurrences of
#include "*.h" --> #include "plplot/*.h" where * is any of the PLplot header
file names (without .h suffix) above.  This massive source code change has
now been completed for all plplot routines and header files.

(2) The double-precision fortran examples work for the first time with
Linux. The way this was done was to abandon the old method of changing the
fortran precision (the -r8 compiler option) which did not work for all
compilers including g77. The new method uses m4 to create the fortran
example source (suffix of .f) from m4 source (suffix of .fm4), and should
work for all operating systems where m4 is available.  (And that should mean
most of them since m4 is part of the GNU tools which can be downloaded
and installed on most systems.)

(3) The libraries have been renamed in a consistent fashion.  The
complicated library name tagging system that was dependent on configure
options has largely been dropped.  The only part of this that is left is the
"d" suffix on core library names if double precision was configured.  (The
matrix library is an exception; no suffix is used in that case since the
library is single precision in all cases.) For Linux, all shared libraries
now have a 3-part version number, and the standard symbolic links (linker
name, and soname) are also created.  To help users get the library and other
linker options correct, I have made a script that echos the linker options
used when linking plrender.  For example, on my Linux system with
double-precision configured here is the result of running the script.

irwin@starling> /usr/local/plplot/bin/plplot_linkage 
 -L/usr/local/plplot/lib -lplplotd -lplmat -litk3.1 -ltk8.2 -litcl3.1 -ltcl8.2 -L/usr/X11R6/lib -lX11 -lvga -ldl -lm -lg2c -Wl,-rpath -Wl,/usr/local/plplot/lib

Results of this script on your system will vary of course depending on what
versions of all system libraries that you have and your configuration
options.

Here is a list of the current plplot libraries:

ls -l /usr/local/plplot/lib/ |grep -v '\.map' |grep -v '\.fnt'
total 1288
-rw-rw-r--    1 software software    34310 Dec 27 17:39 libplcxxd.a

-rwxrwxr-x    1 software software    89968 Dec 27 17:37 libplcxxd.so.5.0.1*
-rw-rw-r--    1 software software    11762 Dec 27 17:39 libplmat.a
lrwxrwxrwx    1 software software       13 Dec 27 17:39 libplmat.so -> libplmat.so.5*
lrwxrwxrwx    1 software software       19 Dec 27 17:39 libplmat.so.5 -> ./libplmat.so.5.0.1*
-rwxrwxr-x    1 software software    16565 Dec 27 17:37 libplmat.so.5.0.1*
-rw-rw-r--    1 software software   459048 Dec 27 17:39 libplplotd.a
lrwxrwxrwx    1 software software       15 Dec 27 17:39 libplplotd.so -> libplplotd.so.5*
lrwxrwxrwx    1 software software       21 Dec 27 17:39 libplplotd.so.5 -> ./libplplotd.so.5.0.1*
-rwxrwxr-x    1 software software   384395 Dec 27 17:37 libplplotd.so.5.0.1*

To avoid name clash problems all core names start with pl.  Also both static
and shared versions of the library are tagged identically, "d" for double
precision and no "d" if single precision or the matrix library.  I have also
taken this opportunity to move to lower case names.  These new library names
are still not chiselled in stone, and may change again within the week.  For
example, I am considering moving from plmat to plmatrix.  But in any case if
you look in the appropriate lib directory or pay attention to the results of
plplot_linkage, you should be okay.

These three changes have been thoroughly tested on my Linux (Debian potato)
system.  In fact, I would claim from the results of these Linux tests that
cvs HEAD is more stable than our 5.0.0 release.  (For access to the plplot
cvs HEAD follow the directions in www.sourceforge.net/projects/plplot.)
However, these changes are untested on non-Linux systems.  If these changes
generate a problem for any system, don't hesitate to get in touch with me,
but be prepared to do some of the work yourself to get things straightened
out since I don't have access to systems other than Linux.

[Plplot-general] yPlot has moved to SourceForge

[Alan W. I. <ir...@be...>]

As many of you know, yPlot is maintained by Conrad Steenberg and myself as
an extremely convenient front end to plplot which is easy to learn.  We
have just decided to move the yplot project from Conrad's old place of work
to SourceForge.  The new web site is http://yplot.sourceforge.net, and the
SourceForge project page is http://sourceforge.net/projects/yplot/.  Thanks
to Conrad's recent efforts all our old rpm's are now official file releases
of the project (see our project page to get access).

The yplot and plplot projects are closely connected so for now we will use
this plplot mailing list for any yplot announcements or discussion to keep
everything together in one convenient location.

Although the current yplot API is quite extensive it still does not yet give
access to the full plplot API, and my current goal for the yplot project is
to address this issue.  For example, I am currently working on debugging the
yplot interface with plshade, allowing excluded areas for that function, and
also implementing a yplot call to plplot's plscmap1l. The latter should make
it be possible to have a grey-scale shaded plot from yplot just as for
plplot.  If there is some other plplot API you would especially like to see
implemented in yplot, please let me know on this list.

When I get my current yplot changes done, I will package the improved yplot
as a tarball.  Watch here for an announcement.  rpm and deb packages of the
new stuff will have to wait until some other issues are settled.

When the image is rotated to an upright "0.0" position, the fonts
drastically
improve to my mind.  Mike claims Imagetick does an even better job.
I browsed the net and it seemed like Imagetick was not freeware.  Does it
cost anything or not?

I found on linux you have to just add gif and png here and there and it
works (see my
latest version of attach notes).  However, there is a bug or two that might
be fixed in an
autoconf program.  Right now I have to fix by altering both libpng and
plplot.

The origianl author of the code is Randy Phillips, who has helped out
with various things over the years, including these drivers, and also
kick starting the www.plplot.org web site (which I think was in turn
based on previous work by Noel Gorelick).

I have these files somewhere around here, but I don't know exactly
where right now.  Randy made this contribution somewhat before the
"Great PLplot Rehosting", (which shall forever be noted as a time of
great tumult and tribulation in the PLplot community), and I have
never really gotten back around to working on that and getting them
fully checked in.  I think the main outstanding issue for me, isn't
the drivers themselves, but the work that will be needed on the
autoconf system to automate their configuration, as we do for the Tcl
and other similar such driver support.

Someday I will, but I really cannot make promises about dates here, as
I am quite busy at work.  If anyone can't wait, they are free to do a
cvs checkout, make the mods, and submit a patch.

Re: [Plplot-general] Where is the PNG driver ? (wrong attachment)

[Michael <Mic...@ms...>]

Let me be clear.  I am not the developer of this code.  The fellow that 
developed the code post the information to the old plplot mail list and I 
get it from him and tried it out.  I just happened to still have a copy of 
the plplot library that included that code when Dan asked.
The fonts were not good enough for the data analysts I write code for and I 
no longer use it.

Geoff seems to know about this code and may recall the author,  I've had 
this stupid laptop crash so many times I have lost all the email and links 
that I had to him.  I just looked and I have not yet deleted the October 
11, 96 version of code that includes the required mods to include the png 
image format.  I can tar it and upload it again (TPTB clean that site 
regularly), but I do not support this code and do not want to include it in 
the CVS until the author can be found and credited.

Re: [Plplot-general] Where is the PNG driver ?

[Dan L. <dle...@ip...>]

      Greta plplot installation (with optional png and gif)
          and linking to greta "One way that works"-ldl 11-16-2000
-------------------------------------------------------------------------

(1) (PNG only) Need libpng.a(so) and libz.a(so). If don't have in /usr/lib,
      These usually come together and are closely synced in versions.  One place to get is:
       http://www.libpng.org/pub/png/libpng.html and get source libpng-1.0.8.tar.gz
       http://www.info-zip.org/pub/infozip/zlib/   and get source zlib-1.1.3.tar.gz
     If you have recent versions of zlib and libpng, you could skip to plplot install.
      Only problem is libpng needs to be patched for png to not core dump on a png file
      write.  zlib actually is probabably fine at /usr/lib/libz.so and need not
      be installed. 
(2) (PNG only) in home directory, gzip -cd libpng-1.0.8.tar.gz | tar -xvf -
                 and              gzip -cd zlib-1.1.3.tar.gz | tar -xvf -
(3) (PNG only) png only.  mv libpng-1.0.8 libpng, and zlib-1.1.3 to zlib
(4) (PNG ONLY)
  To avoid core dumps with png,  I also must change in libpng, file pngwio.c,
    function png_default_write_data, line 51:

   check = fwrite(data, 1, length, (png_FILE_p)(png_ptr->io_ptr));

    change to:
     if (png_ptr->io_ptr)
         check = fwrite(data, 1, length, (png_FILE_p)(png_ptr->io_ptr));

     This change is done is conjucntion with 18 below.
(5) (PNG only) make these libraries.  They are easy, just do ./configure; make
      and you should now have a libpng.a, libpng.so, libz.so, and libz.a
(6) mv $HOME/libpng /usr/lib and mv $HOME/zlib /usr/lib in order to clean things up a bit.
(7) Because of problem with default libpng, need to put it in LD_LIBRARY_PATH path,
     otherwise it finds the one in /usr/lib/libpng.so

-------------------End of libpng and libz (if needed-----------------------
------------------Start of plplot------------------------------------------

I can't mess with changing the /usr area yet.  Also, modifications
to plplot need to be made to add the png and gif drivers.

(1) Obtain the latest version of plplot-990122.gz (os at least the one
    which has code for drivers.  I got it through ftp.msfc.nasa.gov
     via Michael <Mic...@ms...>.  I don't see 
     file plplotlib.tar.Z anymore.
(2) from home directory, gzip -cd plplotlib.tar.Z | tar -xvf - 
(3) cd plplot-990122, 
      ./configure
    (would be ./configure --prefix=/usr/lib/plplot if done for good install)
    ( as root, mkdir /usr/lib/plplot with  rw-rw-rw- on plplot -- again,
       would be for a true install, which I am not yet able to do )
(4) plplot has a typedef PLFLT which can be a DOULBE or FLOAT.  The 
    greta makefile has CFLAGS= -DDOUBLE ..., meaning it has defined
    PLFLT to be a DOUBLE.  Left alone, PLFLT will be a float. Thus, 
    let's be sure its a DOUBLE in all plplot libs:

       edit line 196  of tmp/plplot.h, adding  "#define DOUBLE 1".
    This will insure that the following macro 
           #if defined(PL_DOUBLE) || defined(DOUBLE)
           typedef double PLFLT;
           #else
           typedef float PLFLT;
           #endif
    will always evaluate to typedef double PLFLT;, so no greta/plplot lib
     conflicts arise.
(5) tmp/plDevs.h has many drivers that are not needed. Most can be commented out
     except 
        #define PLD_null 1 (might not need)
        #define PLD_xterm 1 (might not need)
        #define PLD_ps 1
        #define PLD_psc 1
        #define PLD_lj_hpgl 1
        #define PLD_xwin 1
        #define PLD_tk 1 (this is very much needed I believe)
        #define PLD_gif  (add for gif only)
        #define PLD_png  (add for png only)
     note png and gif need to be added.
(6) (GIF and PNG only) 
       cd tmp; cp ../Cver2/gd* .  This picks up gdgif.{c,h} and gdpng.{c,h}
     This with bring in gdgif.c and gdpng.c and headers and backups
(7) (GIF and PNG only) edit tmp/Makefile, add to the "DRIVERS_C" macro
           gdgif.c \
           gdpng.c
(8) (GIF and PNG only) edit tmp/Makefile, add to the "DRIVERS_OBJ" macro
           gdgif$O \
           gdpng$O
(9) (GIF and PNG only).  Make sure you have libgd.so in /usr/lib or /lib
(10) (GIF and PNG only) edit tmp/Makefile, copy the line 
xwin$O: xwin.c plDevs.h plplotP.h plConfig.h plplot.h plstrm.h pdf.h pldebug.h \
  plxwd.h drivers.h plevent.h
paste it twice below, then edit xwin twice in each line to be gdgif$0: gdgif.c ..
and gdpng$O: gdpng.c
(11) (GIF and PNG only) edit tmp/Makefile again, find the macro LDC_LIBS and edit until 
    it looks like:
   LDC_LIBS=-litk3.0 -ltk8.0 -litcl3.0 -litcl8.0 -L/usr/X11R6/lib -lX11 \
       -lgd -lpng -lz -ldl -lm
     It seems that -litk3.0 -litcl3.0 are not needed, not even installed on some systems --
         might try leaving off.
(12) png has a tendency to core dump, as do gifs.  Only solution I found to date in is in
     tmp/gdpng.c check for to see if File handle ?->Outfile is not null before closing it.
     This is done in conjunction with 13 above.  It is unfortunate that I have to change
      libpng.  Because of this, I also have to put it in LD_LIBRARY_PATH path, otherwise
      it finds the one in /usr/lib/libpng.so
(13) Now we are ready to make all plplot libs.  cd $HOME/plplot-990122; make
     should not get any warnings.
(14) Finally we would want to install, with a "make install".  This would populate
    /usr/lib/plplot/ with lib, include, examples, doc directories.  But I
    currently use /home/dleonard/plplot-990122/tmp as the include and lib directory.

--------------------------End of plplot compile/install--------------------------------
--------------------------Start of application compile/install-------------------------

Now in our application, linking and compile statements are not aimed at /usr/lib/plplot yet
but at /home/dleonard/plplot-990122/tmp:

(1)  greta COMPILE Flags:
     OSCFLAGS=-I/home/dleonard/plplot-990122/tmp -DINTEL -DLINUX
     CFLAGS= -DDOUBLE $(OSCFLAGS) -I$(AXAFPROG)/include -I../ututils
    with
     .c.o:
        cc $(CFLAGS) -c $<     
(2) greta LINKING:
     OSLFLAGS=-ldl -L/usr/X11R6/lib -lX11 -ltk -ltcl -lncurses \
      -L/home/dleonard/plplot-990122/tmp -lplplotftk -lMatrix -lgd -lpng -lz
     LFLAGS= $(OSLFLAGS) -L$(AXAFPROG)/lib/$(OSTYPE) -lut -lgzip -lm
   and type is
     cc -o decom98 decom98.o plargs.o libgreta.so $(LFLAGS)

   also have
      ld -o libgreta.so decom98.o decrelay.o (other deleted) -shared

(3) (GIF and PNG) zlib and gzip have two terrible namespace conflicts: they both use "inflate"
    and "deflate".  Best solution I came up with was to rename in gzip.h inflate to inflate_gzip
    and deflate to deflate_gzip.  Then also in src/libgzip-2.4/inflate.c rename function
    inflate to inflate_gzip, and finally src/libgzip-2.4/deflate.c rename function
    deflate to deflate_gzip.
(4) We must also change in greta src/AX/axtlm.c and axtlm.h functions inflate and deflate to inflate_gzip
     and deflate_gzip to insure that they link to the gzip library and not libz
(5) now we can make greta, cd src/AX; rm *.o; make; make install
(6) we are now actually through with plplot-990122, we can hide it with mv plplot-990122 plplot-990122.hide
     I notice that if I do this libMatrix.so is actually found at /usr/lib/libMatrix.so.  libplplotftk
      I believe is statically linked.
(7) (GIF and PNG )  decgui needs to be able to command the new drivers. add lines:
     
           $beDevice->insert( 3, "gif" );
           $beDevice->insert( 4, "png" );

and change $outfile = $vPSFile.$decname.".ps";
    to $outfile = $vPSFile.$decname.".$vDest";

After thoughts:

Worst thing here is the need to modify libpng and not be able to use just the default version in /usr/lib
Modifying plplot has to be done in this version, would be nice if could handle from here.

[Plplot-general] tarball versions of plplot

[Alan W. I. <ir...@be...>]

This is just to remind the list that tarball versions of plplot may be found
at ftp://plplot.sourceforge.net/pub/plplot/. Currently in that directory we
have version 5.0 of plplot (plplot-5.0.0.tar.gz) as our best stable release.
(It supersedes any ancient 4.99 version and also the 1999 January 22 CVS
snapshot, plplot-990122.tar.gz, that a lot of you may still be using.)

As well as the stable release, we have a (very) recent snapshot of the CVS
head, plplot-20001114.tar.gz, at the above ftp site.  This snapshot is of
course experimental and may break, but it may also fix some bugs so it is
worth trying if you are having trouble with the stable version.  I plan to
supply this CVS snapshot as a convenience every month or so, but if you want
the absolutely latest results simply check out the plplot module from the
CVS repository as per the directions at http://sourceforge.net/projects/plplot/.

[Plplot-general] Where is the PNG driver ?

[Andrew R. <ar...@ge...>]

Hi,
   I was just wondering where the source code for the PNG driver lives ? I
have looked through the CVS repository, but can't find it there. If it is
somewhere there, I am missing something. If anyone can point me to where it
is, I would appreciate it.

Re: [Plplot-general] shaded countours

[Alan W. I. <ir...@be...>]

I really like yplot so I have helped Conrad Steenberg with packaging it in
rpm format in the past.  I will probably update the yplot package in the
future, but for now my judgement is yplot itself is okay, but the plplot
package upon which it is based is dated in those old rpm packages.

So for now, I would advise you build a whole new version of yplot for
yourself based on the latest plplot, and that may well take care of the
errors you have encountered.

Download http://www.srl.caltech.edu/personnel/conrad/yplot-1.0.3.tar.gz,
unpack that tarball and follow the general directions there.

But instead of using the plplot version recommended there, I would first try
the latest cvs version of plplot.  If that doesn't work, get back to me.  I
do have yplot working well here based on a slightly older cvs version of
plplot.

yplot also depends on yorick, but on my current Debian system I built yplot
with the normal potato version of yorick without any problems.

Hope this helps.

[Alan W. I. <ir...@be...>]

The list has been quiet because plplot is almost perfect.... ;-)

Seriously, your posting reminded me to announce a new development.

The format of the documentation (and some of the contents) has been greatly
improved thanks to work by Rafael Laboissiere and yours truly.  Please check
out www.plplot.org in the resources section for a link to the new DocBook
form of our documentation.

Currently, I am working on improving the contents of the documentation which
is very easy to do with DocBook source.  If anybody wants to help with this
project or give constructive criticisms of the current effort please get in
touch.

[Plplot-general] shaded countours

[Valery P. <vp...@ai...>]

Dear Plplot fans,

Could you please give me an example of code that drawing the shaded
contours.
I use yplot interpreter which call functions from plplot. But seems to
me there is
a mistake there with function that drawing the shaded contours.

Thanks in advance, Valerij

We want a seemless interface to our greta code which uses plplot for all
output.  Ghostscript and Imagetick introduce whole new software programs.

What we can do along these lines is take a postscript file generated by plplot,
and then use xv to make it a gif.  So again no need for Ghostscript and
Imagetick.

Thanks for the info though I'lll keep it in mind

RE: [Fwd: [Plplot-general] PLplot drivers, is JPEG or PNG or GIF coming soon (along withPostscript)]

[Michael <Mic...@ms...>]

Geoff and Dan,

I have pretty much abandoned the direct PNG code.  I finally got 
ghostscript to output a PNG image and it looks wonderful.  The only problem 
is rotating the landscape image to a landscape view.  I have been using 
ImageMagick to do this.  It takes a noticable, but not dreadful amount of 
time.

I have also finally figured out where in the postscript file to put some 
invisible (background color) text to get acrobat and ghostscript to orient 
the PDF page to a landscape view automatically during the PDF creation.

I use the metafile format only now and render the images as needed.  This 
allows me to include shell scripts and shell commands in my code to get it 
all working.

I can provide more information and some examples if you guys are interested.

Michael

Thanks for your interesting attachment.  I noticed some things in
there that have been on my list of pet peeves for a while.  Eventually
most of that should get resolved, but I am very busy, so patches
against cvs-head are always welcome, and will probably result in
things getting fixed faster than just waiting for me to get around to
it.

I did do some initial work on integrating Randy Phillips png driver
some time ago, but got seriously bogged down with the whole rehosting
to sourceforge thing, and have never gotten back to it.  A key part of
the job is to futz with the autoconf support so it can autodetec
libpng and all that.  One of these days...

I doubt we'll make effort to support GIF with PLplot.  I have enough
troubles in life without inviting attacks from Compuserve lawyers.

Poscript is already well supported, I believe.  Are you have some
particular problem?

Re: [Plplot-general] plplot tcl integration

[Alan W. I. <ir...@be...>]

Vince Darley and I are working on an *experimental* branch of plplot to
allow TEA-based dynamic loading of plplot under tclsh and/or wish.  We are
just in the midst of loading this stuff into the cvs under a separate
branch.  If you want to be a guinea pig for this experimental stuff, it
should be ready for testing shortly.

Watch this space for an announcement.

[Plplot-general] plplot tcl integration

[Kristoffer L. <se...@fi...>]

(Could you reply to this address aswell as I'm not on the mailing list)

I've been looking for a good plotting and graphing package and plplot
would seem to cover those areas. What I want to do is integrate it with
existing Tcl code via a dynamically loadable package. I've installed all
the related systems but have not worked out any way of dynamically loading
the system into Tcl and the online documentation didn't seem to
answer my question. I have tried the following experiment:

bugger:~/download/impress-1.1-beta> itkwish 
% load /usr/lib/libplplotdtk.so 
couldn't load file "/usr/lib/libplplotdtk.so":
/usr/lib/libplplotdtk.so: undefined symbol: Tcl_MatrixCmd

Am I going about this the wrong way? Is it even possible to dynamically
load the system into Tcl (I very much hope so...)?

[Plplot-general] PLplot drivers, is JPEG or PNG or GIF coming soon (along with Postscript)

[Dan L. <dle...@he...>]

Hello plplot people,

We are interested in producing PNG format files.  We currently have a
program that uses PLplot, which has 18
driver/file output options including postscript and postscript color.
However, I don't see any new drivers in the
"developers snapshot" (http://emma.la.asu.edu/plplot/source/) gzip file
to indicate any work towards this very
desirable PNG format file/driver.  I was wondering if anyone knew
whether any such plans are in the works or not, and,
if not, who to contact?

Appreciate the help.

Dan

[Plplot-general] Fetching the code

[Geoffrey F. <fu...@ac...>]

A lot of people are asking me this via email, so let me just put it up 
here on the users-list.

The way to get the code right now, is via anonymous cvs:

zork[30] setenv CVSROOT :pserver:ano...@cv...:/cvsroot/plplot
zork[31] ls
zork[32] cvs login
(Logging in to ano...@cv...)
CVS password: 
zork[33] cvs co plplot
cvs server: Updating plplot
U plplot/.cvsignore
U plplot/CHANGES
...

There is no password for the anonymous account, just hit return.

We will improve www.plplot.org to be more accurate and provide more
conveniences as we are able.  For now, anoncvs is what we have
working.
