Member Function Documentation

TdkImageFormatted * WMSGetMap::getMap	(	std::string	srs,
		std::vector< long > *	themeIds,
		int	width,
		int	height,
		double	xmin,
		double	ymin,
		double	xmax,
		double	ymax,
		long	viewId
	)

Builds an image based on map themes. Get the themeIds related data from the database (if they're found there) and builds a GIF image from the data, projected by srs.

Parameters:

	SRC	data.
	Vector	of all theme id's that the user wants to be in the generated image.
	Desired	width of the image.
	Desired	height of the image.
	Minimum	x coordinate to clip the world.
	Minimum	y coordinate to clip the world.
	Maximum	x coordinate to clip the world.
	Maximum	y coordinate to clip the world.
	Id	of the selected TDK view.

Returns:

Buffer with the generated image data.

void WMSGetMap::safeRelease	(	cdCanvas *&	cv_native,
		cdImage *&	img,
		cdCanvas *&	cv_image,
		TdkCDCanvas *&	canvas,
		TeProjection *&	projection
	)			[private]

Internal helper function to release the allocated resources. Releases the resources allocated by the getMap method (it's called by it).

Parameters:

	Reference	to the CD native (system, Server Image) canvas pointer.
	Reference	to the CD image data pointer of the map.
	Reference	to the CD map image canvas pointer.
	Reference	to the TDK Canvas pointer.
