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.

Note: Not available in Python bindings

Constructor & Destructor Documentation

◆ QgsTilingScheme() [1/2]

QgsTilingScheme::QgsTilingScheme ( )

default

Creates invalid tiling scheme.

◆ QgsTilingScheme() [2/2]

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

Member Function Documentation

◆ crs()

QgsCoordinateReferenceSystem QgsTilingScheme::crs ( ) const

inline

Returns CRS of the tiling scheme.

Definition at line 60 of file qgstilingscheme.h.

◆ extentToTile()

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.

Definition at line 56 of file qgstilingscheme.cpp.

◆ fullExtent()

QgsRectangle QgsTilingScheme::fullExtent ( ) const

inline

Returns the full extent used in the constructor, which might not be square.

Level 0 tile is centered at the full extent and the full extent completely fits into the level 0 tile
