[OpenLayers-Users] [work] Re: icons in Layer.Text

[Robert J Becraft]

See my example at http://www.metaphaze.com/Avalon/AMII_world_map.htm

You will need to use Excell to create the txt file.  Type each column in 
the spreadsheet, then export as a .txt file.  It puts tabs between the 
columns, and makes it readable to OpenLayers.  Using notepad won't 
work.  The column headers are keywords that specify what type of data is 
in that column.  I don't have the link to the help page I found this on, 
it is on the OpenLayer's site though.

I positioned the icon's over the first letter of the layer with the 
country names on it.  You can see this when zooming in.  I did this by 
hand with the spreadsheet open and adjusted the LAT/LON values, 
exporting and reloading the web-page until they were close. 

The icon's themselves are 25x25 pels, I don't adjust the size.  It 
seemed simpler to have them the actual size I wanted them to appear on 
the map.  They are transparent gifs.

Eventually the text detail will come in from a dynamic piece of code I 
haven't finished writing.  One idea I'm toying with is to build a menu 
in the popup that zooms to a variety of features for each of the 
countries.  The final product will depend on my time and how well it 
works when I get to it.
