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
