The following is obsoleted and left for reference only. The latest version of GrWin is available here.

GrWin Graphics Library is a free graphics routine library for Fortran and C/C++ available under many compiler systems on Windows Xp/2000/NT/Me/9x (x86) platforms. Using this library you can enjoy free graphics programming on Windows even if you have no experience on Windows programming.

As a set of interactive drivers for the PGPLOT library on Windows is implemented using GrWin, you can use routines for high level graphics, such as graphs with hidden lines and contour diagrams, etc., in your application.

A bug in the pgplot driver gwdriv.c of GrWin, by which binaries made using resent versions of the Visual Studo do not work, was fixed. Prebuilt binaries for MinGW and Intel Viusual Fortran are available for down load. Users of other systems can make binary files themselves using the latest GrWin toolkit. The development of Ver. 0.99.99 is still :-) in a final stage, and Development Snapshot is available here as a toolkit, which enables you to make library files for GrWin and pgplot from source using your using compiler system. Indivisual files in the toolkit can be accessed from here, and you can check them out to know if each of your downloaded files is the newest.

• Good news for TeXicians
  The next release Ver. 0.99.99 of GrWin will supports the EPS (Encapsulated PostScript) as one of output file formats among others. EPS files generated by GrWin can readily be included in TeX documents. The development of Ver. 0.99.99 is in a final stage, and Development Snapshot is available here as a toolkit, which enables you to make library files for GrWin and pgplot from source using your using compiler system. Indivisual files in the toolkit can be accessed from here, and you can check them out to know if each of your downloaded files is the newest.
  
  Prebuild binaries for GrWin, pgplot and cpgplot libralies and executables of demos are abvailable now only for
  
  • MinGW (gcc + g77),
    
  • Cygwin (gcc + g77),
    
  • Intel (icl + ifort for IA-32),
    
  • Intel (icl + ifort for Intel 64 / EM64T).
    
  Binary files for each compiler system can be rebuilt simply by a make command in a corresponding directory, provided a patched pgplot directory is in the same level of the directories. The msys environment with a gnu make is recommended to be used. Solution/Project files for IDEs of VisualStudio 2003 and VisualStudio 2005 are also availabble, but they only have partially been tested. If you use Fortan, or if you make pgplot library files from source using those files for IDEs, Intel Visual Fortran (ifort) shoud have been installed in your system. Good luck!
  
  Bug reports are very appreciated. I however would make an apology in advance for not replying to every of your reports. Thanks.

News on Apr 4, 2006:

• GrWin is 64-bit ready! A test release for Intel EM64T / AMD64 is available for download here. Bug reports would be very appreciated.

News on Dec 27, 2005:

• The GrWin graphics on g95, a free Fortran 95 compiler, is now available under MinGW and Cygwin. Thanks are due to Mr. D.Cox who gave me this information.
• Makefile.Jp and Makefile.En in the CURRENT release of the GrWinTk have been replaced, because those included in the previous CURRENT release, with the same file name, have bugs.

News on Apr 19, 2005:

• Prebuilt binary of the latest CURRENT Version 0.99.9d (build # 1163052893) for Intel Visual Fortra 8.1 is available for down load here.

News on Jul 4, 2003:

• The latest Version 0.99.9b (build # 1116265826) released:
  • Routines for the tortoise graphics, a.k.a. the turtle graphics, are added to the Library.
  • Easy installations using installer packages each of which is prepared for a specific compiler system. Using a installer package PGPLOT can also be installed.
  • More supported compiler systems; Intel(R) C++/Fortran and OpenWatcom C/C++/Fortran77 newly added.
  • f2c (a Fortran77 to C translator) is available under Intel(R) C++, Borland C/C++, Microsoft Visual C++ and Digital Mars C/C++ for users who do not have a Fortran compiler.
  • GrWinTk-0.99.9b toolkit (source code for the library to drive the grwnd.exe graphics engine) is available.

News:

• With a slightly modified version dp-anm.f of the dp.f, source code for double penduram animations in the distributed sample programs, you can make animated GIF files using IrfanView (to convert each frame of EMF to GIF) + Animation GIF Maker (to save animated GIF), for example.
