Member Function Documentation

void te::wms::WMSLayerRenderer::draw ( te::map::AbstractLayer *  layer, te::map::Canvas *  canvas, const te::gm::Envelope &  bbox, int  srid, const double &  scale, bool *  cancel  )

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.
