DESCRIPTION

d.slide.show is a UNIX Bourne shell macro which clears the entire screen, creates a series of display frames on the graphics monitor, and displays in slideshow format each of the raster/vector map layers listed in the user-specified mapsets. This is a shell script example which makes extensive use of GRASS and UNIX commands. Users are encouraged to examine this macro and develop similar on-line demos using their own data files.

EXAMPLE

The following command sequence shows the available raster maps, saves the view to a PNG file and then converts it into a PDF file: 
# reset region:
g.region -dp

# open GRASS monitor with defined size:
GRASS_WIDTH=800 GRASS_HEIGHT=1000 d.mon x0

# we have around 40 maps in the Spearfish PERMANENT mapset:
d.slide.show across=5 down=8 mapsets=PERMANENT

# From Monitor to PNG to PDF:
d.out.png out=spearfish_maps.png res=2

convert spearfish_maps.png spearfish_maps.pdf
xpdf spearfish_maps.pdf
