Constructor & Destructor Documentation

te::map::MapDisplay::MapDisplay ( )

It initializes a new MapDisplay.

virtual te::map::MapDisplay::~MapDisplay ( )

virtual

Virtual destructor.

Reimplemented in te::qt::widgets::MapDisplay.

Member Function Documentation

virtual const te::gm::Envelope& te::map::MapDisplay::getExtent ( ) const

virtual

It returns the world extent showned by the MapDisplay.

Returns: The world extent showned by the MapDisplay or NULL if none is set.

Note: The extent coordinates are in the Map Display SRS.

Implements te::map::AbstractMapDisplay.

virtual te::map::AlignType te::map::MapDisplay::getHAlign ( ) const

virtual

It returns the MapDisplay current horizontal align.

Returns: The MapDisplay current horizontal align.

Implements te::map::AbstractMapDisplay.

virtual unsigned int te::map::AbstractMapDisplay::getHeight ( ) const

pure virtualinherited

It returns the MapDisplay current height in pixels.

Returns: The MapDisplay current height in pixels.

Implemented in te::qt::widgets::MapDisplay.

virtual double te::map::AbstractMapDisplay::getHeightMM ( ) const

pure virtualinherited

It returns the MapDisplay current height in millimeters.

Returns: The MapDisplay current height in millimeters.

Implemented in te::qt::widgets::MapDisplay.

virtual std::list<AbstractLayerPtr> te::map::MapDisplay::getLayerList ( ) const

virtual

virtual int te::map::MapDisplay::getSRID ( ) const

virtual

It return the Spatial Reference System used by the Map Display.

Returns: The Spatial Reference System used by the Map Display.

Implements te::map::AbstractMapDisplay.

virtual te::map::AlignType te::map::MapDisplay::getVAlign ( ) const

virtual

It returns the MapDisplay current vertical align.

Returns: The MapDisplay current vertical align.

Implements te::map::AbstractMapDisplay.

virtual unsigned int te::map::AbstractMapDisplay::getWidth ( ) const

pure virtualinherited

It returns the MapDisplay current width in pixels.

Returns: The MapDisplay current width in pixels.

Implemented in te::qt::widgets::MapDisplay.

virtual double te::map::AbstractMapDisplay::getWidthMM ( ) const

pure virtualinherited

It returns the MapDisplay current width in millimeters.

Returns: The MapDisplay current width in millimeters.

Implemented in te::qt::widgets::MapDisplay.

virtual void te::map::AbstractMapDisplay::refresh ( bool redraw = false )

pure virtualinherited

It updates the contents in the map display.

Implemented in te::qt::widgets::MapDisplay, and te::qt::widgets::MultiThreadMapDisplay.

virtual void te::map::MapDisplay::setAlign	(	te::map::AlignType	h,
		te::map::AlignType	v
	)

virtual

It will set the align rendering of objects into the map display. Just successive drawings will be affected by this modification.

Parameters

h	The new horizontal align.
v	The new vertical align.

Note: It will not automatically redraw the objects, you must explicit call the setExtent method.

Implements te::map::AbstractMapDisplay.

virtual void te::map::MapDisplay::setExtent	(	te::gm::Envelope &	e,
		bool	doRefresh = `true`
	)

virtual

It sets the world visible area and refreshes the contents in the map display.

If the given area is not proportional to the device width and height, the MapDisplay will change it in order to preserve the aspect ratio.

Parameters

e	The world visible area.
doRefresh	If true the display will refresh its contents.

Precondition: The world coordinates must be in the map display SRS.

Implements te::map::AbstractMapDisplay.

Reimplemented in te::qt::widgets::MapDisplay, and te::qt::widgets::MultiThreadMapDisplay.

virtual void te::map::MapDisplay::setLayerList ( const std::list< te::map::AbstractLayerPtr > & layers )

virtual

It sets the layer list to be showed in the Map Display.

Parameters

layers The layer list.

Implements te::map::AbstractMapDisplay.

virtual void te::map::MapDisplay::setSRID	(	const int &	srid,
		bool	doRefresh = `true`
	)

virtual

It sets a new Spatial Reference System to be used by the Map Display.

It will also convert the current envelope coordinates to the new SRS. This may cause changes to the world visible area. In this case, the extent will be updated and new internal transformation function will be calculated.

Parameters

srid	The new Spatial Reference System to be used by the Map Display.
doRefresh	If true the display will refresh its contents.

Implements te::map::AbstractMapDisplay.

Reimplemented in te::qt::widgets::MapDisplay.
