Example 3: Overlays and the 'file_of_filenames'
In this example, we provide simple overlays and introduce the use of the
'file_of_filenames' parameter, where the image filenames are specified
in a separate (from the config) file.
Note also that we enable the "debug" window -- this contains (sometimes)
useful information when you are setting up your site. You probably do not
want to use it otherwise.
The config file looks like this:
<![CDATA[
debug=true
file_of_filenames=fof3.txt
controls = overlay
controls_style = padding:5px;background-color:green;
overlay_labels=Map, Temperature, Streamlines
overlay_labels_color=white, cyan, black
overlay_labels_style=font-family:arial;color:white;font-size:14px;padding:2px;background-color:green;
overlay_tooltip = Show map, Show temperature values, Draw streamlines
]]>
And the file_of_filenames file contains just one line:
<![CDATA[
TIR1.GIF overlay=TMAP.GIF, TSFC1.GIF, TSTR1.GIF
]]>
