Detailed Description

3 The class encapsulates tiling scheme (just like with WMTS / TMS / XYZ layers).

The origin (tile [0,0]) is in bottom-left corner.

Constructor & Destructor Documentation

QgsTilingScheme::QgsTilingScheme ( )

default

Creates invalid tiling scheme.

QgsTilingScheme::QgsTilingScheme	(	const QgsRectangle &	fullExtent,
		const QgsCoordinateReferenceSystem &	crs
	)

Creates tiling scheme where level 0 tile is centered at the full extent and the full extent completely fits into the level 0 tile.

Definition at line 20 of file qgstilingscheme.cpp.

QgsCoordinateReferenceSystem QgsTilingScheme::crs ( ) const

inline

Returns CRS of the tiling scheme.

void QgsTilingScheme::extentToTile	(	const QgsRectangle &	extent,
		int &	x,
		int &	y,
		int &	z
	)		const

Returns coordinates of a tile that most tightly fits the whole extent.

void QgsTilingScheme::mapToTile	(	const QgsPointXY &	pt,
		int	z,
		float &	x,
		float &	y
	)		const

Returns tile coordinates for given map coordinates and Z level.

Definition at line 35 of file qgstilingscheme.cpp.

QgsRectangle QgsTilingScheme::tileToExtent	(	int	x,
		int	y,
		int	z
	)		const

Returns map coordinates of the extent of a tile.
