Member Function Documentation

void te::map::QueryLayerRenderer::draw ( AbstractLayer *  layer,
Canvas *  canvas,
const te::gm::Envelope &  bbox,
int  srid 
)
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
layerThe layer that will be drawn.
canvasThe canvas were the layer objects will be drawn.
bboxThe interest area to render the map.
sridThe SRS to be used to draw the layer objects.

Implements te::map::AbstractRenderer.
