## 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
