[winGRASS] Re: [GRASS-user] Re: Cygwin winGRASS 6.2 (Working!) and Slide Show (not working)

Hi,

Sorry for the late reply, I am working on the animation aspect, still could 
not get d.slide.show to work.

For the previous cygwin winGRASS installation problem, I have used the 
cygcheck for g.region and the DLL error is cygpg dll cannot be found.  
Searching that on cygwin site gave the libpd4 and postgresql, all the 
mentioned packages are missing on the initial setup.ini.

As for the d.slide.show, I have used the following commands provided because 
I do not have a raster file:

d.mon x0
d.slide.show prefix=G_Newmap

The xmon window only displayed a number of specified monitors but with 
blanks, i.e. no vector graphics or any graphics displayed. My question are:

1)  Do I need to create a raster file for the slide show to work.
2) What is the usual (correct) behaviour of the d.slide.show function, i.e. 
does it shows the specified vector files each at one time on each of the 
specified monitors?

Many thanks in advance for your help.

Best Regards
Casey
