Member Function Documentation

crs()

QgsCoordinateReferenceSystem QgsVtpkTiles::crs

(

)

const

Returns the coordinate reference system of the tiles.

Definition at line 397 of file qgsvtpktiles.cpp.

extent()

QgsRectangle QgsVtpkTiles::extent

(

const QgsCoordinateTransformContext &

context

)

const

Returns bounding box from metadata, given in the tiles crs().

Definition at line 402 of file qgsvtpktiles.cpp.

isOpen()

bool QgsVtpkTiles::isOpen

(

)

const

Returns whether the VTPK file is currently opened.

Definition at line 83 of file qgsvtpktiles.cpp.

layerMetadata()

QgsLayerMetadata QgsVtpkTiles::layerMetadata

(

)

const

Reads layer metadata from the VTPK file.

Definition at line 250 of file qgsvtpktiles.cpp.

matrixSet()

QgsVectorTileMatrixSet QgsVtpkTiles::matrixSet

(

)

const

Returns the vector tile matrix set representing the tiles.

Definition at line 388 of file qgsvtpktiles.cpp.

metadata()

QVariantMap QgsVtpkTiles::metadata

(

)

const

Returns the VTPK metadata.

This method returns the contents of the "root.json" file.

Definition at line 88 of file qgsvtpktiles.cpp.

open()

bool QgsVtpkTiles::open

(

)

Tries to open the file, returns true on success.

Definition at line 48 of file qgsvtpktiles.cpp.

operator=()

QgsVtpkTiles & QgsVtpkTiles::operator= ( const QgsVtpkTiles &  other )

delete

rootTileMap()

QVariantMap QgsVtpkTiles::rootTileMap

(

)

const

Returns the root tilemap content, if it exists.

This method returns the contents of the "tilemap/root.json" file.

Since

QGIS 3.32

Definition at line 340 of file qgsvtpktiles.cpp.

spriteDefinition()

QVariantMap QgsVtpkTiles::spriteDefinition

(

)

const

Returns the VTPK sprites definitions.

Definition at line 161 of file qgsvtpktiles.cpp.

spriteImage()

QImage QgsVtpkTiles::spriteImage

(

)

const

Returns the VTPK sprite image, if it exists.

Definition at line 205 of file qgsvtpktiles.cpp.

styleDefinition()

QVariantMap QgsVtpkTiles::styleDefinition

(

)

const

Returns the VTPK style definition.

Definition at line 127 of file qgsvtpktiles.cpp.

tileData()

QByteArray QgsVtpkTiles::tileData	(	int	z,
		int	x,
		int	y
	)

Returns the raw tile data for the matching tile.

Returns a null byte array if the requested tile does not exist.

Will return an empty byte array (as opposed to a null byte array) if the tile exists but has a zero size.

Definition at line 431 of file qgsvtpktiles.cpp.
