Constructor & Destructor Documentation

◆ MercatorImageRequest()

MercatorImageRequest::MercatorImageRequest	(	const ConstPointer< WebMercatorTileService > &	service,
		Bounds< 2, fltp08 >	bounds,
		Vector< 2, uint04 >	size,
		WebMercatorTile::DPI	dpi = WebMercatorTile::DPI::e_auto )

Constructs a request from a tile service, geographic bounds, image size, and DPI.

Parameters

[in]	service	The tile service to use for generating URLs.
[in]	bounds	The WGS-84 geographic bounding box for the request.
[in]	size	The desired output image dimensions in pixels.
[in]	dpi	The DPI setting (defaults to automatic selection).

References dpi, WebMercatorTile::e_auto, service, and size.

Member Function Documentation

◆ getDPI()

WebMercatorTile::DPI MercatorImageRequest::getDPI ( ) const

Returns the effective DPI setting for this request.

Returns: The DPI value, resolving e_auto if necessary.

◆ getResolution()

WebMercatorTile::Resolution MercatorImageRequest::getResolution ( ) const

Returns the tile resolution appropriate for this request.

Returns: The Resolution value to use.

◆ getScaleFactor()

fltp08 MercatorImageRequest::getScaleFactor ( ) const

Returns a scale factor derived from the DPI and resolution settings.

Returns: The scale factor as a floating-point value.

Note: Purpose is unclear; may relate to converting between tile pixels and output pixels.

◆ getUUID()

UUID MercatorImageRequest::getUUID ( ) const

Computes a UUID that uniquely identifies this request based on its parameters.

Returns: The computed UUID.
