Which package exactly are you installing? Unless you are a cygwin user
already, stick with the superpak.

Yes, they should not work unless you are working from a cygwin shell; these
wrappers are written in perl, for windows I've rewritten them in visual
basic (see scripts above Contents/.) If you are not a cygwin user, you need
not worry about these details. Just install the Windows superpak, let it
automatically add the "grads" bin directory to your path and you should be
good to go, either from the [start] menu, from a icon on your desktop or
from the windows command line (cmd.exe).

Hi,

it is the closest point. When you set an arbitrary (lon,lat) point of your choice on the command line, for example, 
a message says what point is going to be used.

Greetings,
Ricardo

If I plot a variable at a particular point that falls somewhere in between the grid points of the file I am ingesting, does my output reflect the nearest neighbor model grid point data or is it interpolated between the four surrounding grid points?

Thanks for the reply.

I have the following problems on running OpenGrads 2.0.1 on my Windows machine. After installation a directory is (OpenGracs\Classic)

Which package exactly are you installing? Unless you are a cygwin user already, stick with the superpak.
>> I have used the superpack-installation file (grads-2.0.1.oga.1-win32_superpack.exe)

is created with 4 directories who are linking to certain directories in the Contents directory. Am I correct that these links do not function? Well, at least these links are not working on my machine.

Yes, they should not work unless you are working from a cygwin shell; these wrappers are written in perl, for windows I've rewritten them in visual basic (see scripts above Contents/.) If you are not a cygwin user, you need not worry about these details. Just install the Windows superpak, let it automatically add the "grads" bin directory to your path and you should be good to go, either from the [start] menu, from a icon on your desktop or from the windows command line (cmd.exe).

>> Just to make sure... the links that I am referring to are the bin, data, scripts and test_data directories. I opened them all in a text editor and they all start with !<symlink>.  When I double-click on one of these (e.g. bin)  then Windows ask me which program I want to use to open the file. If these symbolic links don't function anymore, then that is okay for me but I thought that these symbolic links are a nice addition :-)

Kind regards,
Herbert

Dear GrADS users,

If some of you is interested in saving your images with
the large FILLED POLYGONS from the shape files
using the GrADS printim command or other GrADS utilities
that parse the metafile content, it could be fixed.

You have to modify source code to get it working.
Problem is that the filled polygon size
is saved in the metafile/buffer as C short int  (<32765).
The real filled polygon sizes in the shape files like Japan outline
(JPN_adm0.shp) are much larger. The solution I used was to save/write
the filled polygon size in the metafile buffer using two short numbers
instead of one at the write/save stage and restore it on the read/parse
stage.

Have to modify code in:
gxmeta.c
gxsubs.c
gxhpng.c

and the code of related utilities:
gxeps.c
gxps.c
gxgif.c
gxtran.c (this one has one more problem that the buffer
size is statically fixed and could be small in some cases...)

For me now printim works without problem.
Who is interested to get modified code please e-mail me
and I'll send you the modified files.

Sincerely yours,
Sergey Varlamov
