This works fine in my Cygwin/grass6.2.2 installation, although the
GRASS_PNG_READ variable does not seem to be available in grass6.2
http://grass.ibiblio.org/gdp/html_grass62/pngdriver.html so the
overlay thing suggested by Paul wouldn't work.
In that case you might be able to use the g.pnmcomp module to compose
the different PNG files together into one image.
Yes, thanks for the tip -- I didn't think about that option.
Trying the same with native winGRSSS 6.3.0 RC5 is less of a success:
(1) no way to set environment variables via the GUI Output - GIS.m
window; (2) not able to start GRASS via cmd.exe as suggested at
http://grass.gdf-hannover.de/wiki/WinGRASS_Current_Status
by typing the following at the cmd.exe prompt:
C:\grass63RC5\bin\grass63.bat -text
I get the output below:
Welcome to GRASS 6.3.0RC5 (2008)
GRASS homepage: http://grass.itc.it/
This version running thru: Windows Command Shell
(cmd.exe)
When ready to quit enter: exit
Help is available with the command: g.manual -i
See the licence terms with: g.version -c
"cmd.exe" non รจ riconosciuto come comando interno o esterno,
un programma eseguibile o un file batch.
(the Italian error message would sound more or less like: "cmd.exe"
is not recognized as an internal or external command, an executable
program or a batch file.)
That's very strange. Is it possible you have accidentally modified
your PATH environment variable so that it no longer contains the path
to cmd.exe? What does
echo %PATH%
say? (Run straight after you get the error message above).
Also, in case its useful information, did you compile yourself or
which binary version did you use (download location?)

Paul:
echo %PATH% says:
C:\msys\1.0\bin;C:\Perl\bin;
which I have set in the grass63.bat file. When I type cmd.exe at the
command prompt or just put only 'cmd.exe' inside a cmd.bat file, the
Windows Shell starts fine. Even adding '%windir%\system32\cmd.exe' to
PATH environmental variable leaves the error message unchanged.

Glynn:
I am using Windows XP [Version 5.1.2600]. Changing the only reference to
cmd.exe in init.bat to %COMSPEC% eliminates the error message. However,
when I try to render a raster via Paul's command sequence, the PNG
driver works fine but it complains about unknown png file type and no
output.png file is written:
GRASS 6.3.0RC5 (UTM32):C:\cygwin\home\luigi >d.rast sample_raster
PNG: GRASS_TRUECOLOR status: TRUE
PNG: collecting to file: c:\output.png ,

ERROR: write_image: unknown file type: png
Thanks and regards,
Luigi
