Editing Module:MapClip/doc (section)

===Optional parameters===
* ''mapfile'' - specifies a custom set of map files to use.  Map files are in <nowiki>[[ ]]</nowiki> listed from left to right.  If multiple rows are present they should be separated by "|" (I think this can be passed in with {{tlf|!}}).
* ''grid'' - this important parameter specifies the color for a grid of latitude and longitude meridians used to annotate the map.  Omitting it omits the grid.  The spacing of the grid is presently only automatic.
* ''mapwestedge'',''mapeastedge''',''mapsouthedge'',''mapnorthedge'' - optional parameters set the edges in degrees of the entire set of map image files.  Default to -180,180,-90,90.  If mapfile is not specified the default is provided for these and overrides this parameter value (you don't need it).
* ''mapwidthpx'',''mapheightpx'' - tell the program how many pixel an individual map image file has.  I've actually had it work with the wrong figure.
* ''float''- right or left to allow the image to "float" in the html sense (like a normal image)
* ''nowiki'' - returns the html text (a mass of divs and a file link) for display of the map, rather than the map itself.  This is ''not'' the same as simply enclosing the #invoke in nowiki tags.
