Example 4a: Using a different path for overlay files

Here we have moved the overlay images to a different directory than the "base" images, and included the overlay_base parameter to specify the path.

The config file is this:

image_base=http://www.ssec.wisc.edu/hanis/examples/ overlay_base=http://www.ssec.wisc.edu/hanis/examples/images4/ file_of_filenames=./fof4.txt background_static=f controls = startstop, zoom, refresh, show, overlay overlay_labels=map, temperature, streamlines controls_style = padding:5px;background-color:green; overlay_labels_style=font-family:arial;color:white;font-size:14px;padding:2px;background-color:green; overlay_tooltip = Show map, Show temperature values, Capture image, Draw streamlines

And the 'file_of_filenames' now contains these lines:

TIR1.GIF overlay=b4tmap.gif, b4tsfc1.gif, b4tstr1.gif TIR2.GIF overlay=b4tmap.gif, b4tsfc2.gif, b4tstr1.gif TIR3.GIF overlay=b4tmap.gif, b4tsfc3.gif, b4tstr1.gif TIR4.GIF overlay=b4tmap.gif, b4tsfc4.gif, b4tstr1.gif
