map* getCorrespondance ( )

Get a list of configuration keys having a corresponding mandatory ows_*.

Map composed by a main.cfg maps name as key and the corresponding MapServer Mafile Metadata name to use see doc from here :

Returns: a new map containing a table linking a name of a configuration key to a corresponding mandatory ows_* keyword (ie. "fees" => "ows_fees").

void outputMapfile	(	maps *	conf,
		maps *	outputs
	)

Create a MapFile for WMS, WFS or WCS Service output.

Parameters

conf	the conf maps containing the main.cfg settings
outputs	a specific output maps

First store the value on disk

Set a ows_rootlayer_title,

Enable all the WXS requests using ows_enable_request see http://mapserver.org/trunk/development/rfc/ms-rfc-67.html

Set metadata extracted from main.cfg file maps

void saveMapNames	(	maps *	conf,
		maps *	output,
		char *	mapfile
	)

Save the map fullpath in a text file (.maps)

Parameters

conf	the main configuration map pointer
output	the current output for which a mapfile has been generated
mapfile	the mapfile saved to store in the text file

void setMapSize	(	maps *	output,
		double	minx,
		double	miny,
		double	maxx,
		double	maxy
	)

Add width and height keys to an output maps containing the maximum width and height for displaying the full data extent.

Restriction to an image having a size of 640x480 (width * height)

Parameters

output
minx	the lower left x coordinate
miny	the lower left y coordinate
maxx	the upper right x coordinate
maxy	the upper right y coordinate

void setMsExtent	(	maps *	output,
		mapObj *	m,
		layerObj *	myLayer,
		double	minX,
		double	minY,
		double	maxX,
		double	maxY
	)

Set the MAPFILE extent, the the ows_extent for the layer, add wms_extent and wfs_extent to the output maps and call setMapSize.

Parameters

output	the specific output
m	the mapObj
myLayer	the layerObj
minX	the lower left x coordinate
minY	the lower left y coordinate
maxX	the upper right x coordinate
maxY	the upper right y coordinate

Parameters

m	the conf maps containing the main.cfg settings
tmpI	the specific output maps to add the Reference key

void setSrsInformations	(	maps *	output,
		mapObj *	m,
		layerObj *	myLayer,
		char *	pszProjection
	)
