Constructor & Destructor Documentation

tile_map::WmtsSource::WmtsSource	(	const QString &	name,
		const QString &	base_url,
		bool	is_custom,
		int32_t	max_zoom
	)		[explicit]

Creates a new tile source from a set of known parameters.

Parameters:

[in]	name	A user-friendly display name
[in]	base_url	The base HTTP URL of the data source; e. g.: "http://tile.stamen.com/terrain/"
[in]	is_custom	If this is a custom (i. e. not one of the default) tile source; custom sources are saved and loaded from our settings
[in]	max_zoom	The maximum zoom level

Member Function Documentation

size_t tile_map::WmtsSource::GenerateTileHash	(	int32_t	level,
		int64_t	x,
		int64_t	y
	)		[virtual]

Generates a hash that uniquely identifies the tile from this source at the specified level and coordinates.

Parameters:

level	The zoom level
x	The X coordinate
y	The Y coordinate

Returns:

A hash identifying the tile

Implements tile_map::TileSource.

Definition at line 56 of file wmts_source.cpp.

QString tile_map::WmtsSource::GenerateTileUrl	(	int32_t	level,
		int64_t	x,
		int64_t	y
	)		[virtual]

Given a zoom level and x and y coordinates appropriate for the tile source's projection, this will generate a URL that points to an image tile for that location.

This expects the URL to have three strings in it, "{level}", "{x}", and "{y}", which will be replaced with the passed values. See tile_map_plugin.cpp for example URLs.

Parameters:

[in]	level	The zoom level
[in]	x	The X coordinate of the tile
[in]	y	The Y coordinate of the tile

Returns:

A URL that references that tile

Implements tile_map::TileSource.

QString tile_map::WmtsSource::GetType

(

)

const [virtual]

Returns a string identifying the type of map source ("wmts", "bing", etc.)

Returns:

Implements tile_map::TileSource.
