virtual

It draws the layer geographic objects in the given canvas using the SRS informed.

The informed bounding box (bbox) is used to constraint the Layer objects to be drawn. The bbox coordinates must be in the Spatial Reference System given by srid.

Parameters

layer	The layer that will be drawn.
canvas	The canvas were the layer objects will be drawn.
bbox	The interest area to render the map.
srid	The SRS to be used to draw the layer objects.
scale	The current scale to draw the layer.

Implements te::map::AbstractRenderer.

		Chart *	chart,
		te::common::TaskProgress *	task = `0`
	)

private

It draws the data set geometries in the given canvas using the informed SRS.

Parameters

dataset	The data set that will be drawn.
gpos	The geometry property position that will be drawn.
canvas	The canvas were the data set geometries will be drawn.
fromSRID	The SRID of data set geometries.
srid	The SRID to be used to draw the data set geometries.
chart	Chart informations that can be used.
task	An optional task that can be used cancel the draw process.

void te::map::QueryLayerRenderer::drawLayerGeometries	(	AbstractLayer *	layer,
		const std::string &	geomPropertyName,
		te::se::FeatureTypeStyle *	style,
		Canvas *	canvas,
		const te::gm::Envelope &	bbox,
		int	srid
	)

private

It draws the abstract layer in the given canvas using the SRS informed.

The informed bounding box (bbox) is used to constraint the layer objects to be drawn. Here, we assume that the given bbox was pre-processed. i.e. the bbox was clipped and contains the same projection of abstract layer.

Parameters

layer	The abstract layer that will be drawn.
geomPropertyName	The geometry property name that will be drawn.
style	The style that will be used.
canvas	The canvas were the layer objects will be drawn.
bbox	The interest area to render the map.
srid	The SRS to be used to draw the layer objects.

Note: This method consider that the given layer contains vetorial data.

void te::map::QueryLayerRenderer::drawLayerGrouping	(	AbstractLayer *	layer,
		const std::string &	geomPropertyName,
		Canvas *	canvas,
		const te::gm::Envelope &	bbox,
		int	srid
	)

private

It draws the grouping of the abstract layer in the given canvas using the SRS informed.

The informed bounding box (bbox) is used to constraint the layer objects to be drawn. Here, we assume that the given bbox was pre-processed. i.e. the bbox was clipped and contains the same projection of abstract layer.

Parameters

layer	The abstract layer that will be drawn.
geomPropertyName	The geometry property name that will be drawn.
canvas	The canvas were the layer objects will be drawn.
bbox	The interest area to render the map.
srid	The SRS to be used to draw the layer objects.

Note: This method consider that the given layer contains vetorial data.

void te::map::QueryLayerRenderer::drawLayerGroupingMem	(	AbstractLayer *	layer,
		const std::string &	geomPropertyName,
		Canvas *	canvas,
		const te::gm::Envelope &	bbox,
		int	srid
	)

private

It draws the grouping of the abstract layer in the given canvas using the SRS informed.

The informed bounding box (bbox) is used to constraint the layer objects to be drawn. Here, we assume that the given bbox was pre-processed. i.e. the bbox was clipped and contains the same projection of abstract layer.

Parameters

layer	The abstract layer that will be drawn.
geomPropertyName	The geometry property name that will be drawn.
canvas	The canvas were the layer objects will be drawn.
bbox	The interest area to render the map.
srid	The SRS to be used to draw the layer objects.

Note: This method consider that the given layer contains vetorial data.; This method retrieves the layer data using only spatial extent restriction and performs the grouping in memory.
