Detailed Description

This is a singleton for managing all mark renderers instances available in the system.

If you want to render a mark, use commands like: te::color::RBGA** image = te::map::MarkRendererManager::getInstance().render(mark, size);

Constructor & Destructor Documentation

te::map::MarkRendererManager::MarkRendererManager ( )

protected

It initializes the singleton instance of the mark renderer manager.

te::map::MarkRendererManager::~MarkRendererManager ( )

protected

Singleton destructor.

Member Function Documentation

void te::map::MarkRendererManager::add	(	const std::string &	key,
		AbstractMarkRenderer *	renderer
	)

It adds a new mark renderer to the manager.

Parameters

key	The key of the new renderer.
renderer	The new mark renderer that will be added on the manager.

Note

The manager will take the owership of the given mark renderer.

Exceptions

Exception

It will throws an exception if there is already a mark renderer registered with the given key.

void te::map::MarkRendererManager::clear

(

)

It clears the marks renderers of the manager.

void te::map::MarkRendererManager::getAllSupportedMarks

(

std::vector< std::string > &

marks

)

const

It informs the set of all supported marks available in the system.

Parameters

marks

A pre-created vector of string that will be filled with the supported marks names.

Note

All registered mark renderers will be consulted.

static MarkRendererManager & te::common::Singleton< MarkRendererManager >::getInstance ( )

staticinherited

It returns a reference to the singleton instance.

Returns

A reference to the singleton instance.

te::color::RGBAColor** te::map::MarkRendererManager::render	(	const te::se::Mark *	mark,
		std::size_t	size
	)

It generates the image pattern from the given Symbology Enconding Mark element.

Parameters

mark	The Symbology Enconding Mark element that will be used as base to build the image pattern.
size	The size of image pattern that will be generated.

Returns

The RGBA image that represents the mark.

Note

This method will look the name of the mark and try extract the associated rendererKey. The pattern used is "rendererKey://markName". Case empty will be used the default mark renderer.

The caller will take the ownership of the returned pointer.

Exceptions

Exception

It will throws an exception if the image pattern can not be generated.
