Free postscript. software for linux

pdnMesh is an automatic mesh generator and solver for Finite Element problems. It will also do post-processing to generate contour plots and Postscript printouts. GUI support using GTK or MFC (Win32) is available.

The problem definition can be done in any form and given to pdnMesh as an input data file. Drawing Exchange Format (DXF) files can be directly imported to pdnmesh. The quality and the coarseness of the mesh can be controlled by giving input parameters.

- Inputformats BMP, TGA, PNM, PPM, PGM, PBM and those supported by ImageMagick.
- Exportformat Postscript, svg, xfig, swf, pstoedit, emf, dxf, cgm, mif, p2e and sk

A free IDL (Interactive Data Language) compatible incremental compiler (ie. runs IDL programs). IDL is a registered trademark of Research Systems Inc.
Full syntax compatibility with IDL 6.0
ALL IDL language elements are supported, including:
- Objects,
- Pointers,
- Structs,
- Arrays,
- System variables,
- Common blocks,
- Assoc variables,
- All operators,
- All datatypes,
- _EXTRA, _STRICT_EXTRA and _REF_EXTRA keywords...
The file input output system is fully implemented
(Exception: For formatted I/O the C() sub-codes are not supported yet)
netCDF files are fully supported.
HDF files are partially supported.
Basic support for HDF5 files.
Overall more than 240 library routines are implemented. For a sorted list enter HELP,/LIB at the command prompt and look for library routines written in GDL in the src/pro subdirectory.
The WRITEFITS procedure and the READFITS function from the IDL Astronomy Users Library compile and run under GDL.
Graphical output is partially implemented. The PLOT, OPLOT, PLOTS, XYOUTS and TV commands (along with WINDOW, WDELETE, SET_PLOT, WSET, TVLCT) work (important keywords, some !P system variable tags and multi-plots are supported) for X windows and postscript output.
GDL has an interface to python.
No GUI support (widgets) is implemented so far.
GDL is free software licensed under the GPL

Antiword is a free MS-Word reader for Linux, RISC OS, and DOS. Antiword converts the documents from Word 2, 6, 7, 97, 2000, 2002, and 2003 to text, Postscript, and XML/DocBook.
Antiword tries to keep the layout of the document intact.
The programmers version is released under GNU General Public License. Check out the pages of the Free Software Foundation for a more detailed description about this license.
The programmers version does not contain any binaries, but the sources can be used to compile a Linux version. The sources can also be used to compile a version for most variations of the Unix operating system as well.
Users have reported successful compilations on FreeBSD, Solaris, IRIX, Digital Unix (OSF/1), AIX, SCO and HP-UX.
Currently Antiword is able to convert Word documents to plain text, to PostScript, to PDF and to XML/DocBook.
Version restrictions:
- The conversion to XML/DocBook is still experimental,
- The support for the Cyrillic alphabet is still experimental.
Enhancements:
- Displaying of page headers and footers was implemented for PostScript and PDF output.
- "footnote" tags were added to XML/DocBook output.
- Support for text removed by the revisioning system was added.
- The KDE helper script kantiword was improved.

GPlot provides a convenient front-end for gnuplot. GPlot GUI accepts a large set of options to generate a single plot of one or more sets of data (overlaid as necessary). This adds no new functionality to gnuplot, but rather makes it easier to generate gnuplot input.
Sometimes the simplest things can be remarkably difficult to get done. That was my reaction when I first tried to make a few simple plots. I knew about gnuplot, but it took way too long to make my first useful plot.
Perhaps the most frustrating task was trying to do something as simple (to me) as "plot this data with a blue line" or maybe the dauntingly (:-) complex "plot this data with a blue line using triangles for the data points". Eventually, I figured out one answer was this fragment:
set linestyle 10 lt 3 lw 1 pt 8 ps 0.55 plot my.data with linespoints linestyle 10
Alright, Im fed up! No more trying to figure out lt 3 versus lt 5 and pt 3 versus pt 22!
I just want a simple command I can understand that does what I want:
gplot.pl -color red -point triangle my.data
Sure gplot.pl cant handle five or ten million complexities that gnuplot can -- but I dont care. All I want is a way to plot some simple columnar data and get a graphic or
Postscript file of it and I dont want to spend very many seconds figuring it out. If this is what you want too, gplot.pl is for you too.
Examples:
# plot data in 1a.data. Show as X window
gplot.pl 1a.data
# plot 2 sets of data. Show as X window
gplot.pl 1a.data 2a.data
# plot data in 1a.data. Create a Postscript file /tmp/gplot.ps
gplot.pl -type ps 1a.data
# plot data in 1a.data. Create a Postscript file
gplot.pl -type ps -outfile 1a.ps 1a.data
# plot data in 1a.data. Annotate it a little
gplot.pl -title "This is my data" -ylabel "Vertical Axis"
-xlabel "Horizontal Axis" 1a.data
# plot 3 sets of data, specify colors and points
gplot.pl -color green -point uptriangle 1a.data
-color blue -point box 2a.data
-color green -point circle 3a.data
Enhancements:
- This release adds support for gnuplot 4.0.
- It adds support for JPEG output files.
- There is no need to upgrade unless you are on gnuplot 4.0.
- Stay on release 1.1 if you are using gnuplot 3.x.
